▎ 摘　　要

NOVELTY - A graphene oxide modified polyacrylonitrile nanofiber membrane is prepared by using 10-15 pts. wt. graphene oxide, 80-200 pts. wt. polyacrylonitrile nanofibers, and 3-5 pts. wt. nano titanium dioxide particles. The nano titanium dioxide particles are at least partially embedded in the graphene oxide interlayer structure. The polyacrylonitrile nanofibers are at least partially embedded in the graphene oxide interlayer structure. USE - Graphene oxide modified polyacrylonitrile nanofiber membrane. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene oxide modified polyacrylonitrile nanofiber membrane, which involves dispersing graphene oxide in polyacrylonitrile solution, adding titanate solution, and electrospinning long and short fibers.
