Study on the Structure of Drawn and Low-Temperature Annealed PET Films
연신 및 저온열처리에 의한 PET 필름의 구조변화에 관한 연구
Abstract
In this study, the structure of PET films, which one is drawn after annealed and the other is annealed after drawn, were investigated. Measurements were carried out with density method for crystallinity and x-ray diffraction method for crystallite size and degree of orientation. By the use of Avrami equation, the rate of crystallization and the type of crystal formation have been studied. In this study, the annealing temperatures are 90, 100, 120, 135
