▎ 摘　　要

NOVELTY - A highly anti-contaminant internally supported polyvinylidene fluoride hollow fiber film comprises casting solution composed of graphene i.e. single atom thickness composed of sp2 hybrid orbitals two-dimensional carbon nanostructures, and organic-inorganic compounding additive composed of an inorganic nano additive and an organic hydrophilic pore forming agent at a weight ratio of 3-12: 0.1-4, the inorganic nano additive is nano silica, nano titanium dioxide and nano aluminum oxide, organic hydrophilic pore-forming agent is Tween (RTM: Polysorbate), polyethylene glycol, and polyvinylpyrrolidone. USE - Highly anti-contaminant internally supported polyvinylidene fluoride hollow fiber film. ADVANTAGE - The film can repel the hydrophilic pollution during the operation of the membrane, and enhances the anti-pollution performance of the support film while maintaining a large flux by controlling the large pore structure of the inner support hollow film by the addition amount of the hydrophilic porogen. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing highly anti-contaminant internally supported polyvinylidene fluoride hollow fiber film.
