NOVELTY - A hollow fiber membrane preparing method involves dissolving 18-22 wt.% polyvinylidene fluoride, 10-30 wt.% porogen, 0.5-5 wt.% stabilizer and 0.01-2.0 wt.% graphene in a 45-65 wt.% first solvent to obtain a casting solution, spraying the casting solution and the previously prepared core liquid through a spinneret to form an initial film, the core liquid is a mixture of a second solvent and water, passing a predetermined air gap, introducing the initial film into a gel bath containing a gel solution for curing and setting to form a curing mold, introducing the curing mold into the rinsing tank for rinsing and collecting the rinsing cured film on a spinning wheel to obtain the finished product. USE - Method for preparing hollow fiber membrane. ADVANTAGE - The method enables preparing hollow fiber membrane with improved strength and flux, and reduced pore diameter.
