“…1 It has been used to study the degradation of polymers, 2,3 brought about by radiation in a vacuum, 4,5 photooxidation, 6 simulated low earth orbit environments, 7,8 degradation in solution 9,10 , ageing after plasma treatment 11 and in natural weathering situations. 12,13 The aim of this study was to determine if XPS is a useful technique for detecting the early stages of powder coating deterioration, specifically polyester coatings, which can lead to a lack of corrosion protection.…”
