Abstract
In this study, PTMSP[poly(1-trimethylsilyl-1-propyne)]/PDMS[poly(dimethylsioxane)]-NaY zeolite and PTMSP/PDMS-NaA zeolite composite membranes were made to incorporate zeolite into PTMSP/PDMS graft copolymer in order to improve the selectivity and thermal stability, the drop of permeability by physical aging effect during long period of time for the PTMSP membrane. To investigate the physico-chemical characteristics of composite membranes, the analytical methods such as FT-IR,
본 연구에서는 PTMSP[poly(1-trimethylsilyl-1-propyne)]의 기체투과에 대한 선택도와 열적 안정성, 시간에 따른 노화현상으로 인한 투과특성의 감소를 개선하기 위해서 PTMSP/PDMS[poly(dimethylsioxane)] graft copolymer에 zeolite를 삽입하여 PTMSP/PDMS-NaY zeolite 복합막과 PTMSP/PDMS-NaA zeolite 복합막을 제조하였다. 물리 화학적 특성을 FT-IR,
