Abstract: 초록: 순수 PMMA와 methacryl-polyhedral oligomeric silsesquioxane(Ma-POSS)를 5 wt% 첨가한 PMMA를 박막 (~650 nm)과 초박막(~50 nm)으로 제조하였으며, 유리전이온도(T g )와 등온 물리적 시효에 미치는 박막의 두께에 미치 는 POSS의 첨가 효과를 시차주사열량계(DSC)를 이용하여 조사하였다.Abstract: Thin (~650 nm) and ultrathin (~50 nm) films of neat PMMA and PMMA containing 5 wt% of methacryl-polyhedral oligomeric silsesquioxane were prepared in this work. The effects of film thickness and POSS on glass transition temperature (T g ) and isothermal physical aging were investigated by means of dif…
