    Abstract: PURPOSE: A hydrophobic porous material is provided to remarkably improve hydrophobic properties of surface of macroporous material and micro porous layer and to manufacture highly hydrophobic porous material with self-washing function. CONSTITUTION: A manufacturing method of improved hydrophobic porous material comprises: a step of providing a porous material with micron-scale surface roughness; a step of forming a surface of a micron-nano double structure by forming pores with forming pores of a sink shape or nanometer-scaled protrusions by plasma etching the surface of the pores ; a step of forming a hydrophobic thin film on the surface of micron-nano double structure. The pore is a sole macroporous support or consists of laminating microporous layer on a macro porous support.
