초록
본 연구에서는 고분자 소재 중 하나인 폴리(에틸렌 테레프탈레이트)(poly(ethylene terephthalate), PET) 필름의 표면을 친수성으로 개질하기 위하여 기상 불소화 및 초음파 수세를 실시하였다. 표면 처리된 PET 필름의 표면 특성은 접촉각, 표면 자유에너지, 주사전자 현미경(FE-SEM), 원자간력 현미경(AFM), X선 광전자분석법(XPS)을 통하여 분석하였다. 직접 불소화 및 초음파 수세 처리된 PET 필름의 물 접촉각은 10.8°으로 미처리된 PET에 비하여 85% 감소하였고, 총 표면 자유에너지는 42.25 mNm^(- 1)으로 미처리된 PET에 비하여 650% 증가하였다. 또한 RMS(root mean square) 거칠기는 1.965 nm로 미처리된 PET 필름에 비하여 348% 증가하였으며, 친수성 관능기인 C-OH 결합의 농도는 약 3배 가까이 증가하였다. 이는 직접 불소화 및 초음파 수세 처리된 PET 필름 표면에 형성된 친수성 관능기와 공동화 현상에 의한 화학적 식각 반응에서 기인한 것으로 생각된다. 이 결과로부터, 기상 불소화 및 초음파 수세 처리법은 PET 필름 표면을 친수성으로 쉽게 개질할 수 있는 효과적인 방법으로 기대된다.
In this study, poly(ethylene terephthalate) (PET) was treated with fluorination and ultrasonic washing treatment for hydrophilic modification of PET film. We measured the change of surface modified PET film surface characteristics using contact angle, surface free energy, FE-SEM, AFM and XPS. After direct fluorination and ultrasonic washing treatment, the water contact angle was measured to be 10.81°, 85% reduction compared to the untreated PET film. Total surface free energy has been measured to be 42.25 mNm^(-1), 650% increase compared to the untreated PET film. Also RMS roughness has been measured to be 1.965 nm, 348% increase compared to the untreated PET film. Hydrophilic functional group C-OH bond concentration has increased approximately 3 times. These results are attributed to the hydrophilic functional group and cavitation due to chemical etching. From this result, it was suggested that the fluorination-ultrasonic washing treatment method could be useful to make PET film surface hydrophilic.
