Water-induced high lubricating coatings are a class of functional coatings that exhibit moderate coefficients of friction (COF) and excellent stability under dry conditions, yet demonstrate significantly reduced COF and superior lubricity once contact with water. These coatings hold substantial application potential in interventional medical devices such as urinary catheters, intravascular catheters, and gastrointestinal catheters. However, current existing water-induced high lubricating coatings generally suffer from complex fabrication processes, high costs, poor adhesion, and insufficient stability. To address these challenges, this study developed a water-induced high lubricating coating on polyvinyl chloride (PVC) surfaces using a composite system comprising polyvinylpyrrolidone (PVP), pentaerythritol triacrylate (PETA), and γ-aminopropyltriethoxysilane (KH550). Experimental results showed that the water contact angle (WCA) of the coated PVC (WHL-PVC) decreased from 84.7° to 22.1°, while COF was significantly reduced from 0.58 to 0.015, indicating substantially enhanced lubricity. In biocompatibility tests, L929 cells co-cultured for 24 h with coating extracts at various concentrations exhibited cell viability exceeding 80%, confirming excellent biosafety. Furthermore, the coating demonstrated outstanding stability and durability in a simulated urine environment. This study presents a novel strategy for developing high-performance medical lubricant coatings, offering significant value for performance optimization and clinical application of single-use interventional medical devices.

A series of PVC-Li 1.6 Mn 1.6 O 4 precursor membranes were prepared by the solvent exchange method using spinel-type lithium manganese oxide powder (Li 1.6 Mn 1.6 O 4 ) as the precursor, poly(vinyl chloride) (PVC) as the binder, and N,N-dimethyl acetamide (DMAc) as solvent. The Li + of the precursor membrane was extracted by treated with HCl solution to obtain PVC-H 1.6 Mn 1.6 O 4 lithium ion-sieve membrane adsorbent. The preparation conditions were investigated by changing the concentration of PVC and Li 1.6 Mn 1.6 O 4 , and the thickness of liquid film . The structure, morphology and adsorption properties of PVC-H 1.6 Mn 1.6 O 4 lithium ion-sieve membrane were carried out by scanning electron microscope and atomic absorption spectrophotometer. The adsorption capacity depended on the preparation conditions. The membrane prepared with concentration of 10 wt% PVC and 15 wt% Li 1.6 Mn 1.6 O 4 in DMAc and liquid film thickness of 0.30 mm is optimum for the adsorption of Li + from aqueous solution. The thickness of membrane prepared under above conditions is about 0.1 mm. Repeated adsorption–desorption test indicates that the PVC-H 1.6 Mn 1.6 O 4 lithium ion-sieve membrane can be effectively regenerated with HCl solution and reused for Li + adsorption without significant loss in the adsorption capacity. Li + adsorption experiments confirm that the PVC-H 1.6 Mn 1.6 O 4 lithium ion-sieve membrane possesses high selectivity for Li + in the presence of Na + , K + , Ca 2+ and Mg 2+ . According to the coefficients, the isothermal data correlated with the Langmuir model better than the Freundlich model, and the adsorption process follows a pseudo-second-order kinetic model .

As a widely used general-purpose plastic, polyvinyl chloride (PVC) suffers from limited thermal stability, inherent brittleness, and a difficulty in balancing mechanical strength with toughness. To overcome these limitations, aramid nanomaterials (ANM)—formed through the self-assembly of poly(terephthaloylterephthalamide) (PPTA) molecules as the reinforcing phase—are directly constructed via an in situ synthesis (ISS) strategy in PVC/NMP and PVC/NMP/LiCl systems. Results demonstrate that this method achieves uniform dispersion and strong interfacial bonding of ANMs within the PVC matrix, significantly refining the composite microstructure. Compared with neat PVC, the PVC/ANM composites prepared by the ISS method showed a significant increase in both tensile strength and toughness, effectively breaking the conventional strength–toughness trade-off. In addition, these composites show enhanced thermal stability and flame retardancy, primarily due to strong interfacial interactions between the ANMs and the PVC matrix. This work not only confirms the great potential of the ISS strategy for preparing high-performance PVC composites but also provides a new technological pathway for addressing common strengthening and toughening challenges in polymer-matrix systems.

This effort is to investigate three different Cu-based oxygen carriers (OCs) with polyvinyl chloride (PVC) and coal in chemical-looping combustion (CLC). The combustion process and synergetic analysis of PVC with coal were evaluated. There were four stages in the reaction of OCs with PVC, which HCl released from PVC could react with OCs at about 200–400 °C. CuO and CuO modified by limestone showed better immobilization of chlorine while CuO modified by iron ore and chrysolite inhibited the reaction of HCl with CuO. PVC char combustion temperature started at about 500 °C which were lower than that of coal char. The combustion efficiency of PVC CLC was all above 92%, except using Cu-Fe as OC which was about 88%. The presence of ZD in PVC showed positive effect on every stage. The addition of coal inhibited the reaction of HCl with CuO. The presence of PVC in ZD reduced the temperature of coal char and the addition of ZD in PVC increased the reaction rate. The synergistic effect was obvious between the PVC and coal blends which is beneficial for the complete combustion in solid fuel CLC

In this research, the ordered honeycomb-patterned polyvinyl chloride (PVC) porous films were first fabricated with hydrophilic tetrahydrofurane (THF) as a solvent by the “Breath figures” (BFs) method. The effects of polymer concentration, polymerization degree of PVC, and air humidity on the formation of PVC films were investigated. The experimental results indicate that the increase of polymer concentration leads to the decrease of the hole size of the resultant films, and even makes the porous structure disappear. Besides, the porous films can be easily fabricated with higher polymerization degree of PVC at 40 mg mL −1 . Increasing air humidity is advantageous to form well-ordered porous PVC films with larger hole size.

A series of chitosan-modified inorganic oxyacid salt flame retardants (IOS-CS) were synthesized and used as flame retardants to improve the fire resistance of poly(vinyl chloride) (PVC) composites while improving the mechanical properties of the materials. The thermal stability of the material was analyzed by TG test; the flame-retardant and smoke suppression properties were evaluated by limiting oxygen index (LOI) and cone calorimeter test, and the mechanical properties were analyzed by tensile test and impact test. The TG results showed that the addition of flame retardant can promote the early cross-linking decomposition of PVC composites, not only advance the decomposition temperature of the material but also promote the formation of char layer and increase the char residual content. LOI and cone calorimeter test results showed that stannate chitosan (Sn-CS) can improve flame retardant and smoke suppression more effectively than other samples. Compared with pure PVC, the addition of Sn-CS increased its LOI from 26.6 to 30.5% and reduced the total heat release value and total smoke release by 18.23% and 52.55%, respectively. At the same time, the addition of the flame retardants had no large deterioration effect on the mechanical properties of the material. The tensile properties of flame-retardant PVC were slightly reduced compared with pure PVC, and the impact resistance was even improved to some extent.

Poly(vinyl chloride) (PVC) is a widely used plastics in different industries. It is an intrinsically hard and brittle polymer and requires the use of plasticizers to improve the processability. Commonly used phthalate-based plasticizers have serious toxicity issues and we present alternatives based on epoxidized soybean oil (ESO) and epoxidized cardanol esters (ECEs). ECEs are synthesized from cardanol and three fatty acids (oleic, ricinoleic, and myristic) using 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) as a coupling agent. Their structure and purity are confirmed by Fourier transform infrared spectroscopy (FTIR) and Nuclear magnetic resonance. Moreover, plasticized PVC films are prepared using a solvent-free method. The replacement of 10 phr of ESO with 5 phr of ECE improves the plasticizing power due to the co-solvency effect. Mechanical properties and thermal stability of plasticized PVC films are correlated with the chain length and the number of epoxy groups in ECE. The best plasticizing effect is observed for epoxidized cardanol-myristate (ECD-MA). ECD-MA as a shorter-chain secondary plasticizer is more compatible with ESO and allows higher conformational mobility of PVC chains. PVC/30ESO/5ECD-MA polymer exhibits an exceptionally high initial thermal decomposition temperature (314.4°C) while preserving moderate ductility and tensile strength (263.4% and 23.3 MPa). Overall, this study highlights the potential applicability of ECD-MA in combination with ESO as a sustainable, bio-based plasticizer and heat stabilizer for flexible PVC products.

The development of a heat stabilizer with good thermal stability, plasticizing performance, and migration resistance for polyvinyl chloride (PVC) is still a notable challenge. In this work, two bio-based heat stabilizers, epoxidized cardanol oleate (ECD-OA) and epoxidized cardanol myristate (ECD-MA), were designed and synthesized with different lengths of their alkyl chains and different epoxy contents to provide outstanding compatibility with PVC. After confirming the chemical structures of ECD-OA and ECD-MA by proton nuclear magnetic resonance and Fourier-transform infrared spectroscopy, the thermal stabilizing effects of both epoxidized cardanol esters were compared with those of the traditional CaSt 2 /ZnSt 2 stabilizer and bio-based epoxidized soybean oil. Then, the effects of four different heat stabilizers on the mechanical, thermal, rheological, and optical properties of PVC films were fully studied. The results suggested that the ECD-MA showed the best thermal stability, and the PVC/30DOP/5ECD-MA film did not turn black after 2 h of thermal aging at 200 °C. In addition, the ECD-MA had good compatibility with PVC, and it had a synergistic plasticizing effect, which caused the film to have a high ductility and tensile strength (320.1% and 19.8 MPa, respectively).

Dioctyl phthalate (DEHP), as the most used commercial plasticizer, has been restricted in many polymer products due to its reproductive toxicity to human body. In this study, castor oil based polyol ester(CPE) was synthesized via a simple and efficient way and used as a sustainable plasticizer in poly(vinyl chloride) (PVC) films to replace toxic DEHP. The chemical structure of the obtained bio-based plasticizer was characterized. The oral toxicity test indicated that CPE had toxic doses of over 3000 mg/kg. Tg of PVC films decreased from 87.4 to 19.1 °C, which is lower than PVC-DEHP systems. The tensile strength and elongation at break of PVC films plasticized with 50 phr CPE is 12.10 MPa and 450.15% respectively, which shows more flexible than PVC/50 prh DEHP samples.The DMA and tensile tests results indicated that the plasctizing effect of CPE was more excellent than DEHP. DEHP can be completely replaced with CPE in flexible PVC products.

Knowledge of the influence of microplastics on soil microbiome and nutrients is important for understanding the ecological consequences of microplastic pollution in terrestrial ecosystems. In this study, we investigated whether polyvinyl chloride (PVC) microplastic pollution at environmentally relevant concentrations would affect soil bacterial community and available nitrogen/phosphorus content. The results showed that although PVC microplastics at 0.1% and 1% levels did not have a significant effect on overall bacterial community diversity and composition in soil over the course of 35 days, a number of bacterial genera were significantly reduced or enriched by the presence of microplastics. Potentially due to their effect on certain functional groups, microplastics caused a significant change in soil available P content. It is noteworthy that, depending on soil type, pollution level and plasticizer presence, contrasting effects of microplastics may be observed. Further research is definitely warranted to gain a clearer picture of the threats posed by microplastic pollution in soil environments.

Abstract Poly(vinyl chloride) (PVC) is one of the most used polymers, but the mechanical and esthetic properties can deteriorate for use outdoors because of ultraviolet (UV) light or heat. The addition of stabilizers is indispensable method for improving the stability of PVC. In this work, a facile synthetic method of CeO 2 quantum dots (QDs) was used, for achieving the best dispersion and improvement of anti-UV properties, the surface of CeO 2 QDs was modified by ethyl 3,4-dihydroxybenzoate (EDHB), which was dispersed within the PVC matrix using the casting method to investigate the anti-UV and thermal properties. X-ray powder diffraction spectra (XRD), infrared spectroscopy (FT-IR), high resolution transmission electron microscopy (HRTEM), UV spectrophotometry and thermogravimetric analysis (TGA) were applied to characterize the structures, morphologies, and properties. The results highlighted that EDHB/CeO 2 can help reduce damages of PVC upon exposure to ultraviolet (UV) light and heat.

Hydrothermal carbonization (HTC) is a promising approach for dechlorination of PVC plastic wastes. However, the high dechlorination temperature is one of the key obstacles to the application of it. This work introduced Zn 2 + and urea into the hydrothermal process to lower the dechlorination temperature of PVC plastic and investigated the photocatalytic performance of the derived zinc-loaded solid products. It was revealed that Zn 2+ and urea acted synergistic effects to open up the porous structures and prevent PVC particle agglomeration, so as to facilitate the penetration of hydroxyl and Zn 2+ in to the particles, catalyzing the elimination and substitution of PVC. Particularly, it achieved a remarkable dechlorination efficiency of 99.96 % by HTC at 200 °C in 120 min. By modulating the hydrothermal parameters, the Zn 5 (OH) 6 (CO 3 ) 2 was simultaneously loaded onto the PVC-derived porous hydrochar. After that, the zinc-loaded hydrochar was pyrolyzed into a porous ZnO-C composite material. Serving as a carbon dopant source, the PVC-derived hydrochar reduced the band gap of ZnO, broadening its light absorption range. Benefiting from this bandgap narrowing and extended light absorption, the ZnO-C composite achieved 92.22 % degradation efficiency for TMX in aqueous solution under simulated natural light and maintained high activity over 5 cycles (retaining ∼70.17 % efficiency). This work pioneered a pathway for low-temperature hydrothermal dechlorination of PVC and demonstrated the potential practical application of the derived ZnO-C composites in photocatalysis.
