▎ 摘　　要

NOVELTY - A functionalized graphene sensing film preparing method involves providing three-dimensional network skeleton by electrospinning a polymer material, and preparing a functionalized graphene material by a chemical method. The functionalized graphene material is uniformly supported on the surface of three-dimensional network skeleton and dried to obtain the finished product. USE - Method for preparing functionalized graphene sensing film for use in gas wireless sensing (claimed). ADVANTAGE - The method enables preparing functionalized graphene sensing film with high gas sensitivity and selectivity, and in eco-friendly manner.
