High Resolution XPS of Crystalline and Amorphous Poly(ethylene terephthalate): AStudy of Biaxially Oriented Film, Spin Cast Film and Polymer Melt

摘要

High resolution monochromated x-ray photoelectron spectroscopy (XPS) (core lineand valence band) was used to study poly(ethylene terephthalate) (PET) as biaxially oriented crystalline film, spin cast amorphous film and amorphous polymer melt. On going from crystalline to amorphous PET the C 1s glycol
