▎ 摘　　要

NOVELTY - An organic-inorganic composite ultra-filtration membrane comprises 15-20 pts. wt. polymer resin, 0.02-2% silane functionalized graphene oxide polymer resin, 75-90 pts. wt. N,N-dimethyl acetamide and 1-3 pts. wt. polyethylene pyrrolidone, where the polymer resin is polyvinylidene fluoride, polyacrylonitrile, polysulfone and polyurethane. USE - Organic-inorganic composite ultra-filtration membrane. ADVANTAGE - The membrane is prepared in a simple and easy manner with improved mechanical properties and synergistic anti-pollution properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing an organic-inorganic composite ultra-filtration membrane.
