The copolymer (PAAN-SiO 2 ) of acrylamide (AM), 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS), N -vinylpyrrolidone (NVP) and modified nano-silica (M-SiO 2 ) was synthesized by free radical polymerization in a water solution. The composition, micro-morphology and thermal stability properties of PAAN-SiO 2 were characterized by Fourier transform infrared spectroscopy, thermal gravity analysis and transmission electron microscopy (TEM). The results showed that AM, AMPS and NVP were successfully grafted onto the surface of M-SiO 2 and formed a spherical core–shell structure copolymer. A significant reduction in the filtration volume was achieved after PAAN-SiO 2 added, and this phenomenon was even more pronounced after aging at the high temperature. The filtration volume of base slurry containing 2 wt% of calcium chloride after aging at 180 °C was reduced from 186 to 6 ml after adding 2 wt% of PAAN-SiO 2 , which exhibited a special property of anti-calcium contamination at high temperature. The interaction mechanism between PAAN-SiO 2 and bentonite and calcium ions was analyzed by particle size analysis, scanning electron microscopy, TEM and X-ray diffraction. Because of the stretching of polymer chain under 180 °C that more amide, sulfonic acid groups and cyclic rigid groups were exposed and the strengthening of the connection between PAAN-SiO 2 and clay prevents a large amount of ion exchange between Ca 2+ and clay layers, reducing the agglomeration of clay. Meantime, the distribution of clay particles was more extensive and some particles with a size of 1–10 μm plugged the micro-nano-pores on the filter cake, and eventually the thin and compact filter cake was formed.

The low water permeability of reduced graphene oxide (RGO) membranes limit their wide applications in water treatment. Herein, a new route to fabricate a lignin nanoparticles-intercalated RGO composite membrane with high flux is reported. The addition of alkali lignin (AL) not only contributed to the reduction of graphene oxide (GO) in the hydrothermal reduction process, but also intercalated between RGO nanosheets . The AL/RGO nanosheets were further cross-linked with polydopamine (PDA) to stabilize the interlayer structure and finally assembled onto a glass fiber (GF) membrane by a vacuum filtration process. The AL/RGO@PDA membrane shows a large pure water flux up to 2410.3 L/m 2 h, which increased by 297.3% than that of the RGO composite membrane (810.7 L/m 2 h) without nanoparticles intercalated. Even after 10 cycles, the AL/RGO@PDA membrane remained high separation efficiency (above 99.10%) for n-hexadecane emulsion. In addition, such a membrane maintained the original performance at high temperature (98 °C) and in highly corrosive environments (pH=1, pH=14). Overall, this study provides a facile and eco-friendly method to fabricate high flux RGO composite membrane, showing promising application for water purification and separation.

Deep and ultra-deep drilling operations face significant challenges such as high temperatures and salinity levels. Drilling fluids are prone to failure under these conditions, causing increased filtration loss and frequent downhole accidents. To address these critical issues, this study utilised the high-temperature-stable adsorption properties of siloxanes to synthesise a multi-target adsorption-type fluid filtrate reducer, PFS-1. The molecular structure and thermal stability of PFS-1 were characterised using 1 H NMR, Fourier transform infrared spectroscopy and thermogravimetric analysis. Its effects on the microstructure of drilling fluid were investigated using scanning electron microscopy, X-ray diffraction and zeta potential analysis, thereby elucidating the interaction mechanism between PFS-1 and clay particles. Experimental results demonstrate that PFS-1 possesses excellent thermal stability, with a decomposition onset temperature exceeding 318°C. After thermal ageing at 240°C for 16 h and 72 h, the filtration loss of drilling fluid containing 2 wt% PFS-1 was 9.1 mL and 9.7 mL, respectively. Additionally, in a 15 wt% NaCl brine-based drilling fluid system, the API filtration loss was just 5.6 mL after ageing at 220°C with 2 wt% PFS-1. Results confirm the superior high-temperature resistance and salt tolerance of the novel filtration reducer. Through the synergistic effect of Si–O–Si chemical adsorption and ionic bonding, PFS-1 forms a stable multi-point adsorption on the surface of the clay particles, inhibiting their hydration and aggregation and thereby reducing the fluid filtration loss. Furthermore, the performance of PFS-1 was improved by 18.75 % compared to that of commercial products, indicating its strong potential for application in demanding drilling environments characterised by ultra-high temperatures and high salinity.

The improper disposal of waste oil and industrial oil-water emulsions presents critical ecological and energy challenges, driving the development of robust separation technologies. This study introduces a stainless steel mesh-supported polyperfluorinated ethylene-propylene/carbon nanotube (SSM-FEP/CNTs) composite membrane fabricated via a one-step thermoplastic sintering method. The innovative design leverages CNTs to create a three-dimensional bridging network within the FEP matrix, enhancing mechanical stability, optimizing pore architecture (average pore size: 0.15–0.30 μm), and establishing tubular nanostructured channels for efficient oil transport. The membrane exhibits exceptional stability in harsh environments, with < 5 % performance degradation in pH 2–14, and high temperatures (up to 100°C) during the continuous filtration tests, validated by SEM, FTIR, and TGA analyses. The one-step sintering process ensures scalability and cost-effectiveness, with a maximum flux of 52 L·m⁻²·h⁻¹ for kerosene, surpassing conventional polymer membranes. By integrating mechanical robustness, chemical inertness, and structural and transport properties, this composite membrane addresses limitations of low flux, poor durability, and complex fabrication in traditional systems, offering a sustainable solution for industrial wastewater treatment, waste oil recovery (e.g., refineries, marine applications), and closed-loop resource management. Its ability to maintain ultrahigh efficiency and durability under challenging conditions positions it as a transformative technology for environmental remediation and sustainable manufacturing.

Phthalonitrile resins as a unique class of high-performance materials have attracted increasing interest in wide application fields including aerospace, electronic packaging and flame-retardant materials. In this article, the boron element was incorporated into phthalonitrile resins to improve the processibility and thermal stability. The synthetic borate and aryl borate-modified resorcinol-based phthalonitrile monomers (BPN and PBPN) showed lower melting points than traditionally employed RPN. The presence of hydroxyl groups leads to autocatalytic curing behavior of BPN and PBPN. Due to the presence of the boron-branched structures in the polymer backbone of the modified phthalonitrile resins, these resins exhibited better thermal stability than traditionally investigated RPN and their mechanical properties are stable over a wide temperature range, which is crucial in service under harsh environments. The results suggest that boron-modified phthalonitrile resins possess great potential in the field of high-temperature resistant materials.

Facing the increasingly serious problems of plastic waste pollution and food waste, edible superhydrophobic coatings have received extensive attention from researchers because of their excellent anti-adhesion performance, which can effectively prevent liquid food from adhering to the inner wall of containers. In this study, we designed a heat-resistant and edible superhydrophobic coating by leveraging the unique and robust hierarchical structure of Lycopodium spore powder (LSP) and utilizing natural low surface energy carnauba wax (CW) as the binder. The focus was to evaluate the hydrophobicity, heat resistance, and mechanical properties of the coating and to further demonstrate its application on liquid food packaging surfaces. The results confirmed that the superhydrophobic coating (LCW) prepared by the coating exhibited excellent superhydrophobic properties (WCA>150°, SA<4°) and excellent self-cleaning function. It also has excellent anti-adhesion properties to food liquids with high viscosity and complex composition, such as honey and yogurt, etc. (it only takes 5170 ms and 2930 ms to completely slip on a surface with about 10° tilt, respectively). The incorporation of Lycopodium spore power notably enhanced the thermal stability of the coating, allowing it to retain a temperature of 150 ° even after being subjected to high-temperature treatment at 120 ℃ for 2 hours. We posit that this lycopodium-coated water-repellent material offers a promising avenue for the efficient production of biodegradable superhydrophobic coatings and holds significant potential for applications in functional food packaging.

Humidity sensors play a crucial role in various sectors, including industrial applications, environmental monitoring, and human health. With the increasing adoption of self-powered humidity sensors, it is imperative to develop devices that exhibit adaptability across multiple environments. In this study, we designed a high-temperature resistant, self-powered, flexible, and highly responsive (TPC) humidity sensor based on ceramic fiber paper (CFP), intended for fire alarm systems and rapid humidity monitoring. The sensor incorporates ceramic fiber paper as the core substrate, PI tape as the thermal insulation protective layer, and employs manganese dioxide and aluminum foil as the positive and negative electrodes, respectively. Thanks to the superior moisture absorption and conductivity of the electrolyte material, the TPC sensor can spontaneously generate voltage across a broad range of 40–95 % relative humidity (RH) at 25 °C. Remarkably, a single TPC sensor can produce a voltage of 0.92 V at 95 % RH, yielding a maximum power output of 28.88 μW. The TPC sensor demonstrates excellent cycling stability in both high-temperature and room-temperature environments. By integrating the TPC sensor with a microammeter, fire alarm is realized. Furthermore, applications of the TPC respiratory rate monitoring, diaper monitoring, and non-contact switching are demonstrated.

Natural polymer materials are increasingly utilized in drilling fluid additives. Starch has come to be applied extensively due to its low cost and favorable fluid loss reduction properties. However, its poor temperature resistance and high viscosity limit its application in high-temperature wells. This study innovatively introduces for the first time diatomite as an inorganic material in the modification process of starch-based fluid loss additives. Through synergistic modification with acrylamide and acrylic acid, we successfully resolved the longstanding challenge of balancing temperature resistance with viscosity control in existing modification methods. The newly developed fluid loss additive demonstrates remarkable performance: It remains effective at 160 °C when used independently. When added to a 4% sodium bentonite base mud, it achieves an 80% fluid loss reduction rate—significantly higher than the 18.95% observed in conventional starch-based products. The resultant filter cake exhibits thin and compact characteristics. Moreover, this additive shows superior contamination resistance, tolerating 30% NaCl and 0.6% calcium contamination, outperforming other starch-based treatments. With starch content exceeding 75%, the product not only demonstrates enhanced performance but also achieves significant cost reduction compared to conventional starch products (typically containing < 50% starch content).

Organosiloxane resins typically undergo significant thermal degradation , with notable mass loss between 400 °C and 800 °C, which limits its applications in wider fields. To address this problem, zirconium (Zr) was incorporated into the backbone of organosiloxane resins via the sol-gel process. The mass retention of the Zr-modified organosiloxane resins at 1000 °C increased with Zr content, reaching 95.47 wt% and 97.29 wt% in air and argon, respectively. The accretion of the mass retention can be attributed to the formation of crystalline zirconium oxide (ZrO 2 ) structures within the resin matrix. The Zr-modified organosiloxane resins showed storage stability even after 3 months. Uniform, smooth and discernible defect free coatings with thickness of approximately 1 μm were obtained through spin-coating. Compared with the pure organosiloxane coating, the Zr-modified organosiloxane coating showed better thermal stability without significant cracks after heat treatment in air at 450 °C. The results suggest potential applications of this Zr-modified ploysiloxane in thermal barrier protection technologies.

Herein, we report the synthesis of novel heat-resistant microspheres by self-stabilized precipitation copolymerization of styrene (St) and 2,2′-bis[4-(4-maleimidophenoxy)phenyl]propane (BMIP) in an mN-methyl pyrrolidone (NMP)/isopentyl acetate (IPA) mixed solvent. The effects of the solvent composition, monomer feed ratio, monomer, and initiator concentration on the size and morphology of the resultant poly(BMIP-co-St) microspheres were investigated in detail. Monodisperse, highly cross-linked poly(BMIP-co-St) microspheres with number-average diameters ranging from 2.23 to 1.28 μm were successfully obtained at a 1/2 molar ratio of [BMIP]/[St] in NMP/IPA (2/13, v/v). Due to the presence of a rigid imide ring and a highly cross-linked structure, the poly(BMIP-co-St) microspheres exhibited excellent thermal stability with an initial decomposition temperature up to 440 °C and a 30% char residue rate at 750 °C. Additionally, there were some unreacted maleimide groups on the surface of poly(BMIP-co-St) microspheres for further chemical modification, making the poly(BMIP-co-St) microspheres highly interesting as advanced functional materials.

High-temperature heat flux sensors play a pivotal role in detecting the dynamic heat exchange processes of heating and cooling, in high-temperature environments. However, the detection of surface heat flux on curved parts operating at high temperatures remains a formidable challenge. Flexible thin-film heat flux sensors, while offering benefits such as conformal adhesion and excellent portability, are typically limited by low operational temperatures and narrow measurement ranges. This work proposes a high-temperature flexible heat flux sensor based on multi-layered high-temperature resistant ceramics nanofibre membranes that one layer worked as a substrate and the other two work as thermal resistance layers, and direct ink writing platinum sensitive elements with Wheatstone Bridge configuration. The prototype sensor is capable of quantifying heat flux reaching 1330 kW/m 2 and withstands temperature as high as 1200 °C. The sensor is bendable with resistance change only about 0.5 % even when the bending radius was larger than 10 mm. These extraordinary characteristics indicate that such methodology will offer a new way for the development of high-temperature thin-film flexible heat flux sensors, demonstrating considerable potential for applications in high-temperature environments.

In this paper, a soluble polyphthalazine biphenyl ether nitrile containing carboxyl and sulfonic acid groups (SPPBEN-COOH) was synthesized, and a water-soluble sizing agent was prepared to enhance the interface performance and wear resistance of SCF/PPEK composites. SPPBEN-COOH has excellent thermal properties (T g = 244 °C) and good solubility. Compared with UCF/PPEK composites, the wear resistance of the modified composites increased by 52.8 %. In addition, molecular dynamics simulation was utilized to calculate the chemical compatibility between the sizing agent and the resin. Meanwhile, the impact of the sizing agent on the interfacial bonding strength of the composite was investigated. This study not only offers an environmentally friendly approach for enhancing the interfacial and tribological properties of SCF/PPEK composites, but also provides valuable insights for the design of high-performance thermoplastic composites. Additionally, it contributes to a scientific understanding of the microscopic mechanisms involved in interfacial enhancement.
