Abstract: The present disclosure provides a method for manufacturing a porous film, including: preparing a polymer mixture solution, wherein the polymer mixture solution includes polycaprolactone and at least one hydrophobic polymer; adding solid particles as a dispersing agent to the polymer mixture solution and mixing the solid particles with the polymer mixture solution, wherein the amount of solid particles added is enough to convert the polymer mixture solution into a solid mixture; drying the solid mixture to form a film; and washing the film with a washing fluid to remove the solid particles from the film to form the porous film, wherein the weight ratio of the polycaprolactone to the at least one hydrophobic polymer is about 1:0.1-10, and wherein the weight ratio of the polycaprolactone and the at least one hydrophobic polymer to the solid particles is about 1:0.01-250.
