摘要： This disclosure concerns a method of forming a porous material, comprising impregnating a porous polymer with a pore-forming agent in order to form an impregnated polymer, and at least partially carbonising the impregnated polymer at a temperature of about 150° C. to about 500° C. in order to form the porous material. The porous material is characterised by a crystallinity of about 10% to about 70% relative to the porous polymer. This disclosure also concerns the porous material thereof.
