Abstract

Nanocomposites of poly(ε-caprolactone) (PCL) and tungsten trioxide (WO₃) were prepared by solvent casting using 5 and 10% of WO₃ nanoparticles. The nanocomposites were characterized using several analytical techniques such as XRD, SEM, thermal analysis (TGA and DSC), spectroscopic methods (FTIR and UV/Vis) to gather information on the modifications introduced by WO₃. Photodegradation of PCL/WO₃ nanocomposites was studied exposing the samples to a Xenon lamp, which simulates the UV spectrum of the sun. The results obtained showed that due to the incorporation of WO₃ nanoparticles, the nanocomposites exhibit higher thermal stability together with higher photodegradation efficiency.
