Abstract

Coloration of polyethylene terephthalate (PET) films by using 3 MeV proton beams was studied by means of absorption spectroscopy, electron spin resonance (ESR) spectroscopy and Fourier transform infrared absorption (FT-IR) spectroscopy. Absorbance of the films increased with the dose and faded in time. Absorbance changes are caused by formation of color centers. The color centers had three components: permanent, long-lived and short-lived. Long-lived and short-lived color centers were formed by reactive species such as radicals. Annealing of color center is well explained by a proposed sequential process.
