Flexible Reduced Graphene Oxide/Polyacrylonitrile Dielectric Nanocomposite Films for High-Temperature Electronics Applications

Polymer dielectrics possess excellent flexibility compared with inorganic ceramic materials. However, the relatively low dielectric constant and working temperature significantly constrain their widespread application. Here, we report a low-cost facile strategy to develop flexible polymer-based composite films with high dielectric constant over a broad temperature. Polyacrylonitrile (PAN) nanofiber mats containing graphene oxide (GO) with...
