▎ 摘  要

NOVELTY - Wide temperature stable isotropic high-elastic porous graphene based composite foam comprises interconnected three-dimensional network structure, and network skeleton is a graphene-carbonitride composite film, where graphene-based composite porous foam has micron-sized interconnected macro pores having a pore diameter of 1-100 mu m. USE - Used as wide temperature stable isotropic high-elastic porous graphite alkenyl composite foam. ADVANTAGE - The composite foam provides a material basis for flexible conductors, sensors, micro-mechanical electronics and flexible energy storage devices and preparing method is simple, adjusts microscopic folds and has easy large-area for preparation of foam. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing wide temperature stable isotropic high-elastic porous graphene based composite foam, comprising applying ice as a porous self-template to freeze-dry a uniformly mixed precursor solution to form a 1-100 mu m interconnected macro porous, carrying out low-temperature heat treatment to reduce the formation of carbonitride by in-situ polymerization of graphene oxide, forming wave structure of 0.01-2 mu m spontaneously on the pore walls of graphene-carbonitride, and combining randomly oriented wave structures to form composite hierarchy.
