Multifunctional Polyimide/Carbon Nanofiber Composite Aerogels for Electromagnetic Interference Shielding, Thermal Insulation, and Joule Heating
The rapid development of electronic devices has increased demand for lightweight, multifunctional shielding materials. In this work, a polyimide-based composite aerogel incorporating oxygen-functionalized/acidified carbon nanofibers (CNFs) was successfully fabricated via freeze-drying followed by thermal imidization....
