NH3 플라즈마 처리한 폴리스티렌 막에서 CO2의 수착과 투과특성

Abstract

The applicable possibility of dual-mode sorption/mobility model and the change of mean permeation coefficient as the change of the plasma input power were investigated from the sorption and permeation experiments of CO2 in polystyrene membrane treated with NH3 plasma. The sorption experiment carried out using a pressure decay method and the permeation experiment carried out using a variable-volume method. The sorption and permeation behavior of CO2 were simulated well in terms of the dual-mode sorption and mobility model. The mean permeation coefficient was decreased under 80 W of the plasma input power but increased above 80 W of the plasma input power.
