▎ 摘　　要

NOVELTY - Preparing wrinkled graphene oxide/nano fiber composite film comprises combining polymer spinning solution and graphene oxide dispersion to surface of support layer to obtain a composite film, and subjecting composite film to heat treatment or chemical treatment to prepare wrinkled graphene oxide/nano fiber composite film, the polymer spinning solution is combining with support layer using an electrostatic spinning method, and the graphene oxide dispersion with support layer using an electrostatic spray method. USE - The preparing wrinkled graphene oxide/nano fiber composite film is useful for preparing separation material (claimed). ADVANTAGE - The film: dispersing as spacer material between nano fiber networks, reduces probability of dense packing of nano fibers, improves porosity of electro spun nano fiber membranes, and increases resulting composite adsorption capacity of membrane. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for wrinkled graphene oxide/nano fiber composite film.
