摘要註:	本實驗使用塑譜儀Brabender將聚碳酸酯(polycarbonate, PC)和環烯烴共聚合物(cyclic olefin copolymer, COC)以不同重量百分比混合。經可見光譜儀測量發現PC/COC共混膜穿透率很低。由掃描式電子顯微鏡(Scanning Electron Microscope, SEM)觀察發現PC與COC為兩相不連續。PC/COC共混膜水氣穿透率和比重會隨著COC的增加而下降。使用紅外線光譜儀(Fourier Transform Infrared Spectroscopy, FTIR)發現PC在3039cm-1的C-H鍵會隨著COC添加而向低波數方向漂移。利用電漿輔助氣相沉積方法(Plasma Enhanced Chemical Vapor Deposition, PECVD)對PC/COC比例為70/30之共混膜進行表面氧電漿處理，再使用衰減式全反射紅外光譜儀(Attenuated Total Reflectance Fourier Spectroscopy, ATR-FTIR)測量經氧電漿處理後表面官能基的變化。再以接觸角量測系統(contact angle analyzer)量測發現經過氧電漿處理會使接觸角下降成為親水性。由原子力顯微鏡(Atomic Force Microscopy, AFM)觀察經氧電漿處理後因為氧電漿蝕刻使表面的粗糙度下降，造成附著度下降。COC添加確實改善PC水氣阻隔低的特性，再利用PECVD進行氧電漿處理更能提升共混膜水氣阻隔能力。 In this study, polycarbonate and cyclic olefin copolymer were mixed different weight radios by brabender. UV/VIS/NIR spectrometers measured PC/COC blends and found it has low optical transmission. Scanning Electron Microscope(SEM) observed PC and COC were immiscible. Water vapor transmission rate(WVTR) and specific gravity were reduced for the blending film at the COC increased. C-H group of the PC at 3039cm-1 peak shifts to lower wavenumbers direction with COC increasing. The blends surface were treated by Plasma-Enhanced Chemical Vapor Deposition. Surface function group is measured by Attenuated Total Reflectance Fourier Spectroscopy(ATR-FTIR), and then the contact angle were measured. Here we found that it will make the contact angle were lowered and the suface was became hydrophilic. The sample surface roughness was observed by Atomic Force Microscopy(AFM). We found that the surface became smoother of after oxygen plasma treating.It is really improves PC WVTR at the COC increased and oxygen plasma treated blends can have better WVTR.
