POROUS POLYMER MEMBRANE WHICH INCLUDES A FIRST MICROPOROUS SKIN SURFACE, A SECOND POROUS SURFACE, AND A BULK WHICH IS FORMED IN BETWEEN AND A FLUID PROCESSING METHOD USING THE SAME, A MANUFACTURING METHOD OF ASYMMETRY POROUS POLYMER MEMBRANE

摘要

PURPOSE: A porous polymer membrane, a fluid processing method using the same, and a manufacturing method of an asymmetry porous polymer membrane are provided to properly use in the inkjet application by offering a minimum smearing and gel line.;CONSTITUTION: A porous polymer membrane comprises a first microporous skin surface; a second porous surface; a body which is in between the first microporous skin surface and the second porous surface. The first microporous skin surface includes more than about 20 pores/50,000 μm^2 of the pore density. The body includes more than about 120 pores/mm^2 of the pore density.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) First (skin) side; (BB) Second sife; (X-SEC) Cross section
