METHOD OF MANUFACTURING A POROUS RESIN SUBSTRATE HAVING PERFORATIONS AND METHOD OF MAKING A POROUS RESIN SUBSTRATE INCLUDING PERFORATIONS HAVING ELECTRICALLY CONDUCTIVE WALL FACES

摘要

The present invention , in the porous resin base material formed of a resin material containing a fluorine-based polymer , penetrating in the thickness direction step 1 of forming at least one perforation ( ) to ; The inner wall surface of the perforation , by contacting an etching solution containing alkali metal Step 2 of etching treatment ; The deterioration caused by the etching process hwacheung , by contacting the compound or a solution having an oxidizing power , a method for manufacturing a perforated porous resin substrate 3 including the step of removing the alteration hwacheung . Is characterized by a method for producing a porous resin base material to the inside wall surface of the perforated conductive screen .
