Harsh-condition protective materials are essential for resisting various types of environmental damage, such as fire, microbes, scratches, and etc. However, integrating multiple functions in one transparent flexible material without sacrificing each other remains a formidable challenge. Here, we demonstrate smart-puffing phosphite-protonated siloxane (PSiP) that simultaneously exhibits excellent fire protection, high-temperature insulation, antibacterial, antimold, self-healing properties. A facile one-step method is developed to create this microporous PSiP using (3-aminopropyl)triethoxysilane phosphite via hydrophilic–hydrophobic interaction-driven self-assembly. Notably, employs an intelligent thermal-responsive self-puffing behavior achieve effectively blocking 87.8% 1400 °C heat. The unique dynamic network with high transparency (>92% the visible region) affords ability well potent defense against bacteria (>99% efficiency). Our findings open up new avenue developing transparent, flexible, high-performance multihazard potential applications buildings, windshields, electronics, beyond.

Medical dressings, as a cover for wounds, can replace damaged skin in the wound healing process to play temporary barrier role, avoid or control infection, and provide favorable environment healing. Therefore, there is an urgent need medical antimicrobial dressings treatment of chronic wounds. Although traditional polyurethane foam has been widely used conventional foams are primarily prepared using nonbiocompatible isocyanate-based compounds, which potentially hazardous both operators applications field. Here, we propose nonisocyanate naturally derived from lignin by enzymatic alkylation, cyclic carbonation modification, polymerization with diamine addition blowing agent.

As a member of the two-dimensional materials' family, MXene sheets exhibit unique structure and outstanding functional properties, garnering extensive interest in many emerging fields. Among them, derivatives with low emissivity inorganic feature have positioned them as promising candidates for thermal camouflage fire safety. Nevertheless, present literature still lacks comprehensive comparative review focused on both radiation protection safety advanced MXene-based nanocomposite materials. This paper is dedicated to offering an overview recent advances progress empowering nanocomposites context synthesis operational principle, structural characteristics, multifunctional performance emergent applications. Special emphasis placed reviewing camouflaging (infrared stealth), flame-retardant (passive) early warning (active) understand relationships between material compositions, fabricating process, multi-scale structures multiple functionalities. Finally, future challenge direction applications are discussed analyzed.

Biomass-based aerogels offer a promising potential as alternatives to plastic-based foams for thermal insulation applications. However, their inherent flammability has hindered practical usage. In this work, we addressed issue by employing layer-by-layer assembly technique deposit two oppositely charged biobased materials, namely phytic acid and chitosan, onto fully aerogel system. These were fabricated using cellulose filaments chitosan cross-linked with citric acid, resulting in mechanically robust 3D structure. The synergistic effects of the deposited significantly enhanced fire resistance mechanical strength. developed six bilayer depositions (LBL6), showed an outstanding peak heat release rate (pHRR) 6.0 kW.m−2, total (THR) 0.4 MJ.m−2, substantially lower than previously cellulose-based foams. LBL6 also demonstrated immediate self-extinguishing behaviour, boasting impressive limiting oxygen index (LOI) value 63 %, which is highest reported aerogel. Furthermore, exhibited superior Young's modulus up 4.5 MPa, surpassing flame-retardant aerogels. Additionally, they excelled properties, conductivity less 38.2 mW·m−1·K−1, placing them same range as, or even than, commercially available insulators. Given simplicity development process well-known advantages completely system, our present sustainable environmentally friendly alternative current commercial insulators that are derived from petroleum-based materials.
