High-Performance Polyimide/Silica Composite Aerogels via KH550-Mediated Chemical Bridging for Improved Thermal Insulation and Flame Retardancy
Aerospace thermal protection requires lightweight, thermally insulating and flame-retardant materials. However, pure polyimide aerogels suffer from high-temperature shrinkage and insufficient strength. Direct incorporation of unmodified silica leads to serious nanoparticle agglomeration and poor interfacial compatibi...
