▎ 摘　　要

NOVELTY - Preparing nanofiber/graphene oxide composite material comprises (i) using composite nanofibers and graphene oxide powder to obtain pretreated composite, (ii) performing solid phase microwave reaction on the pretreated composite to obtain nanofiber/graphene oxide composite material. USE - The method for preparing nanofiber/graphene oxide composite material is useful for preparing seawater desalination membrane (claimed). ADVANTAGE - The method avoids the existing seawater evaporation technology, and problem of low light and heat utilization efficiency. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: 1 nanofiber/graphene oxidecomposite material prepared by above mentioned method; and 2 use of nanofiber/graphene oxide composite material, comprising using the nanofiber/graphene oxidecomposite material and preparing seawater desalination membranes.
