Meta-aramid (PMIA) is a high-performance polymer known for its exceptional properties, however, its molecular chain arrangement and strong hydrogen bonding contribute to its rigidity and brittleness. Additionally, the lack of reactive groups in its molecular structure severely affects the dyeing properties of PMIA, and restrains its applications in various fields. To address these issues, this study introduced 4,4′-thiodianiline (4,4′-TDA) into the main chain of PMIA molecules through copolymerization modification. This approach enhanced the relative molecular weight of the copolymers, resulting in co-PMIAs with improved flexibility. The synthesized copolymers demonstrated excellent mechanical properties and thermal stability, maintaining high strength while improving toughness. Furthermore, the incorporation of this thioether-containing monomer also enhanced the dyeing properties and flame retardancy of PMIA. The modification strategy employed in this research offers valuable insights into the structural modification of aromatic polyamides, and the synthesized novel copolymers show promising applications in the field of protective clothing.

The corrosion of materials severely limits the application scenarios of triboelectric nanogenerators (TENGs), especially in laboratories, chemical plants and other fields where leakage of chemically corrosive solutions is common. Here, we demonstrate a chemical-resistant triboelectric nanogenerator (CR-TENG) based on polysulfonamide (PSA) and polytetrafluoroethylene (PTFE) non-woven fabrics. The CR-TENG can stably harvest biological motion energy and perform intelligent safety protection monitoring in a strong corrosive environment. After treatment with strong acid and alkali solution for 7 days, the fabric morphology, diameter, tensile properties and output of CR-TENG are not affected, showing high reliability. CR-TENG integrated into protective equipment can detect the working status of protective equipment in real time, monitor whether it is damaged, and provide protection for wearers working in high-risk situations. In addition, the nonwoven-based CR-TENG has better wearing comfort and is promising for self-powered sensing in harsh environments.

Silver-printed terylene is presented to fabricate anti-electromagnetic radiation Maternity Dress (AMD) with superior shielding effectiveness, but the use of noble metal as electromagnetic interference shielding materials enhances cost of raw material and restricts its application. In this study, a facile process combined with electroless deposition and hydrophobic treatment to fabricate self-cleaning radiation protection cotton for AMD was established. The active groups on the plant fiber surface could absorb Sn 2+ and Pd 2+ through coordination effect, acting as catalytic center, which can catalyze the reduction of Ni 2+ in the plating solution. Ni particle deposited on the its surface with deposited amount of 32 %. The fabricated material exhibited an shielding effectiveness of 52.5 dB and it meet AMD criteria. Owing to the cooperation of the low surface energy and rough structure of precipitation, the Ni-plated cotton modified with (3-Mercaptopropyl) trimethoxysilane exhibited remarkable hydrophobicity with water contact angle up to 112.8° and excellent self-cleaning property.

Multi-ion fabrics (especially silver ion fabrics) have special advantages as electromagnetic radiation, but the use of noble metals enhances its cost. Electroless nickel plating (EP-Ni) has great potential application in fabricating low-cost metallized material. Here, EP-Ni on pure cotton surface to fabricate radiation protection suits for pregnant woman was established to replace traditional protection suits with silver film. The active groups on the cotton/polyester blend fiber surface could absorb tin and palladium ions, acting as catalytic centers, which can catalyze the reduction of Ni2+ in the plating solution. Ni particle with (111) crystal plane preferential oriented crystal structure deposited on cotton surface with a coarse microstructure. The Ni deposited amount is about 19%. The fabricated material exhibited a shielding effectiveness of 29.5 dB. Studies also shown that bending has no negative effect on crystallinity and electrical property. But more bending times could lead to crack, which would decline electromagnetic shielding performance by 24%.

In this study, a series of reversible thermochromic microencapsulated phase change materials (TC-MPCMs), exhibiting excellent latent heat storage-release performance, were designed and fabricated successfully. The characterization and microstructure regulation of TC-MPCMs were conducted systematically as well. The core of TC-MPCMs was comprised of crystal violet lactone employed as thermochromic colorant, bisphenol A employed as developer and 1-tetradecanol employed as co-solvent, respectively. These influencing factors of encapsulation process such as the amount of emulsifier, stirring rate, feeding weight of core/shell ratio, acid resistance and thermal cyclic durability were carried out to clarify the effect of various experimental conditions. The surface morphology, shell thickness and core–shell structure of TC-MPCMs were characterized via optical microscope (OM), thermal field emission scanning electronic microscope (TFE-SEM), transmission electron microscope (TEM), respectively. From different scanning calorimetry (DSC) analysis, the performance of temperature of fusion and crystallization and enthalpy of TC-MPCMs under various conditions were measured as well. The results of thermogravimetric (TG) analysis illustrated the influence on thermal stability of TC-MPCMs. In addition, Lab color space obtained by colorimeter is certainly intuitive to observe the colorimetric characteristics of TC-MPCMs as well. More importantly, the reversible thermochromic property associated with phase state of the 1-tetradecanol could also provide a visual evidence of energy storage or release performance of the TC-MPCMs. Furthermore, The TC-MPCMs exhibited excellent stability even after 100th thermal cycling test without any obvious performance degradation, including the morphology, phase change properties and thermal stability. In the end, the fire fighter protective clothing containing TC-MPCMs was designed and fabricated, which could provide adequate thermal protection in the various fire environments. Thus, TC-MPCMs developed in this work showed great potential applications in thermal protective clothing and other thermal regulation fields.

The quest for a highly breathable protective clothing with good barrier performance is rapidly rising, especially in the fight against the COVID-19 pandemic. However, commercial protective clothing usually experiences trade-off between air permeability and barrier performance. Herein, a highly breathable and durable polyimide (PI)-based protective clothing material with good barrier performance was fabricated by electrospinning. The structure of PI electrospun nanofibrous membranes (PI-ENMs) was optimized in terms of mechanical strength , filtration efficiency and air permeability. The results showed that the PI-ENM with 500 nm diameter prepared by electrospinning for 4 h had high filtration efficiency (96.13 %), low pressure drop (57.1 Pa) and high-quality factor (0.057 Pa -1 ). The optimized PI-ENM had a high bacterial filtration efficiency of 99.48 %, which meant that it would possess good microbial barrier performance in practical applications. Due to the low air resistance, the PI-ENM demonstrated a high air permeability of 265.44 mm s −1 , which was 40–160 times that of commercial protective clothing. An ultra-thin layer of polydimethylsiloxane (PDMS) was coated on the thermal stable PI-ENMs via chemical vapor deposition to obtain PI-ENM@PDMSs, of which the fire resistance was further enhanced without compromising filtration efficiency and resistance. Moreover, the PI-ENM@PDMSs exhibited strong hydrophobicity , robust mechanical strength, and excellent stability, and can be easily reused via common sterilization methods without impacting its protection performance. Therefore, PI-ENM@PDMSs is a promising candidate for reusable breathable protective clothing.

Functional textiles with enhanced moisture management can facilitate sweat transport away from the skin to improve personal comfort. However, porous materials exhibit low capability of preventing the intrusion of external liquids, becoming a bottleneck in the design of medical protective clothing. Herein, a trilayered composite fabric based on a gradient wettability structure is demonstrated for directional water transport and resistance to blood penetration. The proposed fabric shows distinct advantages, including a high water breakthrough pressure of 2.43 kPa from the external side, an outstanding positive water transport index (1522%), and an antiblood penetration resistance of 2.71 kPa. Moreover, the fabric shows improved comfort with a high moisture transmission (320 g m–2 h–1) and desired water evaporation rate (0.36 g h–1). This work addressed the concern of directional water transport and resistance to blood penetration while providing a comfortable wearing microenvironment, leading to a promising research direction for multifunctional medical textiles.

In recent years, researchers have made efforts to promote the thermal protection capabilities of firefighting suits in response to frequent fire accidents. In this paper, a novel silica/aramid nonwoven fabric (SiO 2 /AF) aerogel composite was prepared by combining AF and SiO 2 aerogel using the sol-gel method and dip coating technology . Polyimide (PI) and zeolitic imidazolate framework-L (ZIF-L) were used as insulation reinforcement materials to fabricate four types of laminated fabrics, namely, the outer layer + waterproof breathable layer + different insulation layers (AF, SiO 2 /AF, 0.8 % SiO 2 /AF/PI and 0.12 % SiO 2 /AF/ZIF-L, respectively). In addition, the fireman uniform was taken as the control group. The results showed that the insulation performance of the composite fabrics was better than that of the control group, and the outer layer + waterproof breathable layer+0.12 % SiO 2 /AF/ZIF-L laminated fabric exhibited the lowest thermal conductivity (0.038 W/(m·K)), best thermal radiation protective performance (RPP) (246.04 kW/m 2 ) and excellent wear resistance (mass loss rate 0.46 %). This significant work will open up broad prospects for the applications of SiO 2 /AF composites in the area of heat-resistant clothing.

Protective clothing should provide comfort for wearers over a wide range of temperatures and adequate protection for body in some harsh environments. In the present work, we prepare lightweight ceramic fibrous mat based on electrospun SiO 2 -TiO 2 composite fiber and a barrier between human body and extreme environments can be designed based on the fabric. The non-woven mat with a density of 0.045 g/cm 3 exhibits high flexibility and toughness, excellent compressibility with good reproducibility over 1000 cycles, and significantly low thermal conductivity of 0.044 W/m·K at room temperature. The addition of TiO 2 reduces the thermal conductivity and improves the infrared reflection ability of the ceramic hybrid fibrous mat. At the same time, the fiber morphology in the mat can maintain at a high temperature, which expands the application of thermal protective clothing in different environment.

Developing ceramic nanofibrous membranes for the thermal insulation layer of firefighting protective clothing is vital. However, previous ceramic nanofibrous membranes were brittle and easy to break during service in high-temperature environments. The lack of elastic and compressible properties has limited the high-end applications of ceramic nanofibrous membranes. In this work, elastic and compressible Al 2 O 3 /ZrO 2 /La 2 O 3 nanofibrous membranes were fabricated via sol–gel electrospinning and calcination in air at different temperatures. The as-fabricated Al 2 O 3 /ZrO 2 /La 2 O 3 nanofibrous membranes can maintain excellent elasticity and compressibility in the temperature ranging from −196 to 1400 °C. Moreover, they have low thermal conductivity and high working temperatures. These favorable characteristics make the Al 2 O 3 /ZrO 2 /La 2 O 3 nanofibrous membranes a promising candidate for the thermal insulation layer of firefighting protective clothing.

The threat posed by biological and chemical warfare agents (BCWA) to national security, the environment, and personal health underscores the need for innovative chemical protective clothing. To address the limitations of conventional activated carbon materials, which are prone to falling off and adsorption saturation, an efficient self-association approach was introduced. In this study, we proposed the immobilization of metal–organic framework (MOF) 808 and Ag nanoparticles onto a polypropylene (PP) fiber membrane using a rapid self-association method facilitated by chitosan (CS). The MOF 808/Ag-based (PP-CS/808-Ag) fiber membrane demonstrated exceptional degradation efficiency, achieving a remarkable rate of t1/2 within 2 h for the mustard simulant 2-chloroethyl ethyl sulfide (2-CEES) and a rate of t1/2 = 4.12 min for the G-series simulant dimethyl 4-nitrophenylphosphate (DMNP). A theoretical computational model was developed to determine the overall reaction mechanism, and it was verified that MOF 808 and Ag nanoparticles were mainly involved in the hydrolysis process against 2-CEES and DMNP. The PP-CS/808-Ag composite fiber film was prepared as the core layer, and the fracture strength, bending resistance, and moisture permeability were better than those specified by many countries for biochemical protective clothing, showing that it has a broad application prospect in developing a generation of broad-spectrum bioprotective clothing.

Chemical protective clothing is crucial for shielding operators from toxic and hazardous substances. However, the limited moisture permeability of these garments significantly affects worker comfort and functionality over long periods. In this study, we introduce a novel graphene oxide/polyurethane composite membrane with an innovative alternating layer structure and improved interlayer bonding, produced through a simple, scalable layer-by-layer assembly method. The outstanding L-GO/PU membrane offers robust chemical protection for up to 24 h against harmful agents like mustard gas and dichloromethane, while also showing excellent resistance to both acidic and alkaline solutions. With a moisture permeability of 3116 g m −2 d -1 , this membrane ensures optimal comfort during extended use. Additionally, it demonstrates remarkable resistance to swelling, maintaining its structural integrity for 27 days during prolonged immersion in water. The L-GO/PU composite stands out as an excellent choice for chemical protective gear, combining high toxicity resistance with superior moisture management capabilities.
