METHOD FOR FORMING A POROUS MATERIAL

Abstract

A method for forming a porous material is to mix a porous first basic material with a sacrificial material compatible with the first basic material to let the sacrificial material permeate into the pores of the first basic material to form a first finished product. Subsequently, the first finished product is mixed with a second basic material and heated over the vaporization temperature of the sacrificial material to let the ingredients of the second basic material change and increase viscous force and impossible to enter the pores of the first basic material. Simultaneously, the sacrificial material is heated and vaporized to exhaust out of the pores of the first basic material, disabling the second basic material to permeate into the pores of the first basic material and thus forming a second finished product for reserving the ingredients in the pores of the first basic material.
