With the increasing development of productivity, new materials that allow for efficient use energy are slowly becoming a sought-after goal, as well challenge is currently being faced. For this reason, we have made aerogels target our research and prepared different series (CLPI (1-5)) cross-linked polyimide by mixing cross-linking heat-insulating agent 1,3,5-tris(4-aminobenzylamino)benzene (TAB) with polyamic acid solution. We created three-dimensional spatial organization using vacuum freeze-drying programmed high-temperature drying, then controlled concentration polyamidate solution to investigate TAB's influence on aerogel-related properties. Among them, shrinkage reduced from 40% in CLPI-1 28% CLPI-5, it also shows excellent mechanical characteristics, highest compression strength (CLPI-5) reaches 0.81 MPa specific modulus 41.95 KN m/Kg. In addition, adding TAB improves aerogel thermal resistance, T

Abstract Mitigating embodied emissions is becoming increasingly crucial as the energy supply shifts toward more sustainable sources. Bio‐based materials present a potentially alternative to synthetic polymers; however, it often do not yet match performance of materials. Given ongoing reliance on high‐performance, high‐environmental‐impact materials, essential ensure their complete recyclability. Aerogels, recognized by IUPAC one top ten emerging technologies, are witnessing rapid market growth in thermal insulation and protection applications. In certain applications, composite aerogels exhibit superior performance, particularly under high temperatures. Here, molecular simulation tools employed elucidate interaction forces between polymers solvents, develop recycling strategy for polyimide‐based aerogels, demonstrate application firefighter textiles runaway Li‐ion battery packs. These composites engineered disassembly, allowing recovery starting without any degradation components after multiple cycles. The recyclable can be fabricated using various manufacturing techniques produce fibers (1D), membranes (2D), complex structures (3D). This unique combination outstanding excellent recyclability facilitates utilization protective clothing, electric mobility, consumer goods, aeronautics.
