The invention provides a preparation method for graphene reinforced polymer porous sponge fiber. The preparation method is characterized in that: the graphene reinforced polymer porous sponge fiber is prepared by subjecting an oxidized graphene solution having a certain concentration to ultrasonic processing to obtain a uniformly dispersed oxidized graphene solution; dissolving a polymer in a solvent to obtain a polymer solution with a certain concentration; adding the dispersed graphene solution into the polymer solution under stirring to obtain a graphene-polymer blend spinning solution; spraying the graphene-polymer blend spinning solution through a spinning nozzle into a coagulating bath to form fiber by utilization of a wet-method spinning device; washing with water, reducing, and washing with water again; and quickly subjecting the wet fiber to freeze drying or supercritical drying to obtain the graphene reinforced polymer porous sponge fiber. The preparation method is simple in technology and low in cost, and is suitable for large-scale production. The fiber has advantages of high strength, good antistatic performance, good elasticity, small density, large specific surface area, and the like. The fiber can be used for preparing heat insulating fabrics in the weaving field, and can be used for water treatment in the environment protection field, and the like.
