▎ 摘　　要

NOVELTY - A hollow nano-silver/graphene/polyethylene ultrafiltration membrane includes 90 pts. wt. polyethylene, 10 pts. wt. polypropylene and 0.1-1 pt. wt. hollow nano silver/graphene. USE - Hollow nano-silver/graphene/polyethylene ultrafiltration membrane used as water channel. ADVANTAGE - The hollow nano-silver/graphene/polyethylene ultrafiltration membrane has unique layered structure due to hollow nano-silver/graphene, advantages of light weight, large specific surface area, and excellent surface permeability, antibacterial and anti-pollution effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the hollow nano-silver/graphene/polyethylene ultrafiltration membrane, which involves: (a) weighing the raw materials according to proportion, performing melt blending extrusion and casting, where the extrusion temperature is 200degrees Celsius, and the thickness of the ultrafiltration membrane is 20-30 mum.
