Abstract
A rough surface was developed on films when precrystallized poly(ethylene terephthalate) films were drawn. The effects of the crystallization temperature and drawing temperature on the development of rough surface were investigated. The morphological features were examined by POM, SEM, and LS. It was found that a lump in rough surfaces consists of several spherulites which remain undeformed in the drawing process. The size of the spherulites and the degree of the crystallinity, in other words, the degree of the volume filling of the spherulites in the film specimen is an important factor in the development of a rough surface. Rough surfaces were also obtained by biaxial elongation.
