Photo‐Degradation of a Biopolyester Blend under UV‐C Rays

Abstract Biopolyesters, pure and mixed with a compatibilizer, are exposed to UV‐C radiation in the interval 4–32 h. rays act as germicides antibacterial on biomedical materials. The mechanical physical characterization tests have shown how all materials, mixed, undergo photodegradation even if different way. change structural order of polymer, embrittlement, surface wettability water/blood is lower blend than polymers. This thanks cross‐linked structure mixture, which more thermally stable, mechanically resistant, hydrophobic individual components.
