The ambition of human beings to create a comfortable environment for work and life in sustainable way has triggered great need advanced thermal insulation materials past decades. Aerogels foams present prospects as insulators owing their low density, good insulation, mechanical robustness, even high fire resistance. These merits make them suitable many real-world applications, such energy-saving building materials, thermally protective aircrafts battery, warming fabrics. Despite advances, date there remains lack comprehensive yet critical review on the materials. Herein, recent progresses fire-safe thermal-insulating aerogels are summarized, pros/cons three major categories aerogels/foams (inorganic, organic hybrids) discussed. Finally, key challenges associated with existing discussed some future opportunities proposed. This is expected expedite development insulating help sustainable, safe, energy-efficient society.

Abstract To adapt to the trend of increasing miniaturization and high integration microelectronic equipments, there is a demand for multifunctional thermally conductive (TC) polymeric films combining excellent flame retardancy low dielectric constant ( ε ). date, have been few successes that achieve such performance portfolio in polymer due their different even mutually exclusive governing mechanisms. Herein, we propose trinity strategy creating rationally engineered heterostructure nanoadditive (FG@CuP@ZTC) by situ self-assembly immobilization copper-phenyl phosphonate (CuP) zinc-3, 5-diamino-1,2,4-triazole complex (ZTC) onto fluorinated graphene (FG) surface. Benefiting from synergistic effects FG, CuP, ZTC bionic lay-by-lay (LBL) strategy, as-fabricated waterborne polyurethane (WPU) nanocomposite film with 30 wt% FG@CuP@ZTC exhibits 55.6% improvement limiting oxygen index (LOI), 66.0% 40.5% reductions peak heat release rate total release, respectively, 93.3% increase tensile strength relative pure WPU between ZTC. Moreover, presents thermal conductivity λ ) 12.7 W m −1 K 2.92 at 10 6 Hz. This work provides commercially viable rational design develop high-performance films, which hold great potential as advanced dissipators high-power-density microelectronics.

The nondegradability, nonreusability, and flammability of epoxy coatings have brought serious environmental safety issues. Herein, a multifunctional, fire-retardant vitrimer coating (DCNC/45PETO) was prepared via curing bis(2,3-epoxypropyl)cyclohex-4-ene-1,2-dicarboxylate (DCNC) with well-designed phosphaphenanthrene-containing polyethylenimine (PETO) at room temperature. DCNC/45PETO exhibits excellent adhesion to different substrates, high adhesive strength 7.9 MPa on wood, outperforming previous wood coatings/adhesives. endows fire retardancy, including limiting oxygen index 34.0% vertical burning (UL-94) V-0 rating. demonstrates durable performances in harsh environments. self-catalytic transesterification within the network effectively avoids application extra toxic catalysts, this can be reused for least 5 times mild conditions without compromising its performances. This study provides an innovative design strategy creating multifunctional coatings, showing great potential construction field.

Abstract Intumescent flame‐retardant coatings offer excellent passive fire protection for flammable materials and steel. However, a key challenge is the conflict between increased melt viscosity from additive catalyst chemical foaming behavior. Herein, “interfacial autocatalytic” strategy‐guided design of double dopant‐free epoxy coating reported with 100 µm boron‐rich upper layer 300 phosphorus‐rich bottom layer. This generates BPO 4 in situ at interface during combustion, synergistically catalyzing charcoal formation expansion process. , its better lattice arrangement, able to form dense ceramic 5.5 stack 10–40 nm nanoparticles, encapsulating an underlying 1.8 cm intumescent char The demonstrates superior thermal insulation heat‐resistant time up 50 min, 271% delay ignition time, ultra‐low growth rate 58% reduction, 33% reduction total heat release. In addition high transparency, this presents easy self‐healing, good mechanical properties, water resistance. autocatalytic strategy confined space‐time introduces new method enhancing catalytic charring flame retardancy.
