What is Photodegradation of Biodegradable Polyesters about?

This study investigates the photodegradation of biodegradable polyesters, specifically poly(L-lactide) (PLLA) and poly(3-caprolactone) (PCL), over 200 hours using various analytical methods. The results indicate that photodegradation occurs via a bulk erosion mechanism, with PCL exhibiting higher photodegradability than PLLA, and the crystallinity of PLLA affects its degradation rates. The findings suggest that the chemical structure adjacent to the ester oxygen is more critical for photodegradability than
