Abstract
본 연구에서는 대기압 플라즈마를 이용하여 polylactic acid(PLA) 필름의 표면 특성 변화를 알아보았다. 극성 용매인 물과 비극성 용매인 Diiodomethane을 사용하여 표면의 접촉각을 측정하고, 이 값을 이용해 표면자유에너지 값을 계산하였다. 또한 대기압 플라즈마의 처리 조건에 따른 PLA 필름의 접촉각과 표면자유에너지 값을 최적화하였다. 그 결과 대기압 플라즈마 처리 시간 30 sec, RF-power 70W, Ar 가스 유량은 6 lpm, 공기 중의 노출 시간은 5 min이었을때가 가장 낮은 물 접촉각을 나타내었고, 표면자유에너지는 가장 높은 값을 나타내었다. XPS 분석을 통해서 대기압 플라즈마 처리 전 후 PLA 필름의 화학적 관능기의 변화를 분석하였으며, PLA 표면에 -C=O, -CO, -COO 등의 변화를 관찰하였다.
This study investigated the surface characteristics of polylactic acid (PLA) film after one atmospheric pressure plasma treatment. We used de-ionized water and diiodomethane as polar and non-polar solvents, respectively, for measuring contact angles, and subsequently calculated the surface free energy of PLA film. The contact angle and free energy of PLA surface were optimized at the treatment time of 30 sec, RF-power of 70 W, Ar gas flow rate of 6 lpm and air exposure time of 5 min. We analyzed the change of chemical functional groups on the surface of PLA film through XPS and were able to observe the change of polar functional groups such as _x000D_
-C=O, -CO, -COO on the surface of PLA film after one atmospheric pressure plasma treatment.
