▎ 摘　　要

NOVELTY - Preparing composite fiber membranes comprises (i) preparing mercapto functionalized graphene oxide; (ii) preparing Polyacrylonitrile (PAN) nano fiber membrane doped with sulfhydryl functionalized graphene oxide by electrospinning technology; and (iii) soaking the PAN nano fiber film doped with sulfhydryl functionalized graphene oxide in the nano silver colloid solution. USE - The composite fiber membranes is useful for improving loading stability of silver nano particles (claimed). ADVANTAGE - The method: produces fiber membranes with scientific reasonable structure and is safe and convenient use; is simple; utilizes simple equipment and normal temperature and pressure; and produces nano fiber membrane material and the membrane material by in-situ reduction and subsequent composite methods are at different pH, temperature with the shedding rate of the film material is 60.81% lower than that of the materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nano fiber membrane stably loaded with nano silver particles, prepared as mentioned above.
