Abstract

Sponge-like porous polypropylene thin film, and a method for preparing a sponge-like porous polypropylene thin film. The method includes dissolving polypropylene in an organic solvent to form a solution under reflux condition; adding a cavity forming agent to the solution and mixing the solution until the cavity forming agent is well-dispersed therein; applying the well-dispersed solution onto the solid substrate through spin coating to form a thin film on the solid substrate; peeling the thin film off the solid substrate; extracting the cavity forming agent from the peeled thin film by washing the peeled thin film in an aqueous or nonaqueous solvent, thereby obtaining a sponge-like porous polypropylene thin film with cavities, macro-voids, and micropores. The sponge-like porous polypropylene thin film is used as an oil sorbent. The sponge-like porous polypropylene thin film has about 400 to about 700 swellable cavities per cm.
