Abstract
Highlights
-
Using electrospun high-strength carbon nanofibers as the aerogel scaffold, high loading of polyaniline in the aerogel was achieved through seed polymerization, forming the core–shell structure fibers and simultaneously connecting the fibers as a stable conductive network.
-
Combining carbon-based materials with conductive polymers like polyaniline significantly improves shielding performance, achieving electromagnetic interference shielding efficiency of up to 84.5 dB and SE d?1 values greater than 791.2 dB cm3 g?1. Flame retardancy reduces PHRR by 65.8%, and thermal insulation with low thermal conductivity of 0.104 W m?1 K?1.
