Feed Gases Dependence on Surface Modification Using Electric Discharge for Polymer Film
Abstract
Liquid medicines like organic solvents are mainly used for conventional surface modification technologies. They change the characteristic of surface by removing particles or changing bonding by oxidizing and inducing functional groups. High reactivity oxidants are easily produced by atmospheric pressure non-equilibrium discharge. Oxidants produced in discharge are selected intentionally to select the feed gas, applications for various materials are expected.
Gas dependence for polyimide film treatment was estimated by using atmospheric pressure non-equilibrium discharge constituted blades to plate electrode with dielectric. It was clarified that the condition of high humidity condition of feed gas had good effect for decreasing the contact angle after treatment, depending on the experimental condition, addition of 3 % H2O had effect as same as applying about 3.5 times of electric power. And more, highly electric power discharge using N2 gas or humid gas had effect for decreasing the contact angle.- Publication:
