Weathering and biodegradation of polylactic acid composite reinforced with cellulosewhiskers

This work focuses on analysis and comparison of accelerated weathering of samples of polylactic acid reinforced with cellulose whiskers (PLA-CW), conducted in QUV chamber-Panel, and their subsequent exposure to biotic soil environment. The cellulose whiskers (microfibrils) were obtained from banana...
