What is Application of Slow Positrons to Coating Degradation about?
Photodegradation of a polyurethane-based topcoat induced by accelerated UV irradiation is studied using Doppler broadened energy spectra (DBES) and positron annihilation lifetime (PAL) spectroscopies coupled with slow positron technique. Signi®cant and similar variations of S-parameter and ortho-positronium intensity (I 3 ) in coatings are observed as functions of depth and of exposure time. The decrease of S is interpreted as a result of an increase of crosslink density and a reduction of free-volume and hole fraction during the degradation process.
