dc.description.abstractIn this paper, poly (dimethyl siloxane) (PDMS) was modified using electron beam irradiation and its property was investigated. PDMS sheets prepared using a conventional thermal curing method were irradiated by electron beams at absorbed doses between 20 and 200 kGy and their properties were characterized using swelling degree and contact angle measurements, universal testing machine (UTM). thermogravimetric analyzer (TGA), and X-ray photoelectron spectrometer (XPS). The results of the swelling degree measurements. UTM, and TGA revealed that the swelling degree of the irradiated PDMS sheets was reduced down to 24% in comparison to the control sheet, and their compression strength and thermal decomposition temperature increased up to maximum 2.5 MPa and 10 degrees C, respectively, due to the increase in crosslinking density by irradiation. In addition, on the basis of the results of contact angle measurements and XPS, the wettability of the PDMS sheets was enhanced up to 24% owing to the generation of hydrophilic functional groups on the PDMS surface by oxidation during electron beam irradiation.-
dc.description.abstract본 연구에서는 전자빔을 이용하여 poly(dimethyl siloxane)(PDMS)을 개질하였으며 그 특성 변화를 분석하였다. PDMS 시트를 기존의 열경화법을 통해 제조한 후 20에서 200 kGy의 흡수선량으로 전자빔을 조사하였고, 조사된 시트들의 특성을 팽윤도 및 접촉각 측정, 만능시험분석기(UTM), 열중량분석기(TGA), X선 광전자 분광기(XPS)들을 이용하여 분석하였다. 팽윤도 측정, UTM 및 TGA 결과, 전자빔 조사에 의해 PDMS 시트의 가교 밀도가 증가함에 따라 조사된 PDMS 시트의 팽윤도는 순수한 것에 비해 최대 24%까지 감소하였고 압축강도와 열분해온도는 순수한 것에 대비각각 최대 2.5 MPa와 10 ℃까지 증가함을 확인하였다. 또한, 접촉각 측정과 XPS 분석 결과를 토대로 전자빔 조사에의한 산화 반응에 의하여 PDMS 표면에 친수성 관능기들이 형성되기 때문에 PDMS 표면의 젖음성은 순수한 것에비해 최대 24%까지 향상됨을 확인하였다.-
