▎ 摘　　要

NOVELTY - A graphene filtering sheet comprises reduced graphene oxide (10), which has carbon/oxygen (C/O) content ratio of 0.1-50 and is dispersed in a macromolecule to become a macromolecule composite sheet. USE - A graphene filtering sheet. ADVANTAGE - The graphene filtering sheet has a capacity of separating alcohol from water with an efficiency approximately 100%, and the method of producing reduced graphene and graphene filtering sheet is simple and does not cause environmental pollution. Selecting proper reduction time of graphene oxide can avoid aggregation of reduced graphene oxide and obtain macromolecule sheet complex of high surface area and surface roughness as low as nano grade. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for fabrication of graphene filtering sheet which involves adding graphene oxide in water to delaminate graphene oxide to obtain graphene oxide dispersion solution, performing hydrothermal reduction process to graphene oxide dispersion solution at 30-100 degrees C for 10 minutes to 72 hours to obtain reduced graphene oxide dispersion solutin the step of drying the reduced graphene oxide (r-GO) dispersion solution is achieved by vacuum filtration. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of reduced graphene oxide.
