PPDA-PMDA polyimide aerogels with tailored nanostructure assembly for air filtering applications

Due to their high porosity and nanoporous morphology, aerogels have presented unique properties and thus offered a very high potential capability to be used in leading applications such as super thermal insulation and nanoparticle filtering. However, controlling the aerogels’ morphology and as a result, tailoring their properties is still a challenge. In this study, polyimide aerogels are developed through imidization of highly reactive...
