NOVELTY - An enhanced type polyethylene hollow fiber film comprises 20-45 mass% polyethylene, 1-5 mass% graphene oxide, 0.02-0.5 mass% composite coupling agent, 1-25 mass% hydrophilic agent, 30-70 mass% diluent and 2-20 mass% pore-forming agent. USE - Enhanced type polyethylene hollow fiber film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing enhanced type polyethylene hollow fiber film, which involves mixing polyethylene with graphene oxide, iron powder and composite coupling agent, after the high-speed mixing, adding the hydrophilic agent, pore-forming agent, and diluent to the ingredients, and mixing to make a film, putting the film-forming material into a slitter to cut a narrow strip of 7-50 mm, and introducing the narrow strip to a winding device and wind it on an organic fiber tube to obtain a hollow fiber tube, passing the compressed air or high boiling point non-solvent as the core liquid into the hollow fiber tube, and introducing the hollow fiber tube into the gas phase or liquid phase separation tank to separate the diluent and pore-forming agent in the film making material to obtain polyethylene hollow fiber membrane filament, introducing the polyethylene hollow fiber membrane filaments to a drying tunnel and sintering at 100-130 degrees C for 10-60 seconds to obtain the finished product.
