Graphical abstractResearch highlights► The UV/ozone degradation on P3OT thin films was investigated by means of non-contact dynamic surface force microscopy and I–V transport measurements. ► A two-stage degradation process of the polymer under UV exposure has been observed, namely chemical and morphological modifications. ► In the early stages, free carrier mobility reduction as a result of the chemical modification occurred.
Followed by a strong structural modification, thickness reduction, oxygen doping and further mobility reduction.
