The lack of degradation of plastic products have imposed problems in the preservation of natural environments and their ecosystems through plastic accumulation. This collection of plastics promotes toxin exposure to wildlife, finding its way into the food chain, affecting both land and marine ecosystems. The project goal is to understand the degradation mechanisms of biodegradable materials and other comparable materials through UV radiation testing. Polylactide (PLA) films and polycarbonate (PC) films will be compared for their relative deterioration from constant UV radiation in a Q-U-V accelerated weather tester for 28 days. Five 3” by 5” samples of 14 mil thick ...
