▎ 摘　　要

NOVELTY - An electrode membrane comprises graphene paper and slurry coated on graphene paper. The slurry comprises 1-10 %mass polyvinylidene fluoride, 60-89 %mass N,N-dimethylacetamide and 10-30 %mass activated carbon. USE - Electrode polar membrane for electrical desalination. ADVANTAGE - The electrode polar membrane has excellent conductive desalination effect, and uses polyvinylidene fluoride to reduce the impedance caused by organic matter, and enhances the current utilization rate, and absorbs more ions, thereby improving the desalination rate and time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for device for preparing electrode polar membrane.
