In Situ Polyimide Modified Polymethylsilsesquioxane Aerogels for Thermal Insulation
The inherent brittleness of silica aerogels severely limits their practical application in thermal protection. To address this issue, polymethylsilsesquioxane (PMSQ) wet gels were fabricated via an aqueous sol–gel method, and polyimide (PI) was introduced through in situ polymerization to construct an inorganic–organic...
