METHOD FOR IMPROVING RELEASING PROPERTY OF MOLD USING LOW TEMPERATURE PLASMA PROCESS

摘要

PURPOSE: A method for improving the releasing property of a mold using the low temperature plasma process is provided to obtain a method for coating on the mold a polymer thin film which not only is not contaminated by materials such as a releasing agent due to the excellent releasing property but also has the high durability due to the high cohesion to the mold. CONSTITUTION: In a method for improving the releasing property of a mold by coating a polymer thin film comprising pretreatment step of treating the mold with the reactive gas plasma; and plasma polymer coating step of depositing the polymer produced by plasma polymerizing a monomer gas on the mold (11), the polymer coating step comprises a binding layer (12) coating step of coating the pretreated mold by polymerizing as gradually increasing the pressure of a reaction chamber (the pressure of the monomer gas); and a functional layer (13) coating step of coating the binding layer coated mold by polymerizing as constantly maintaining the pressure of the reaction chamber.
