Biodegradation and migration behavior of cellulose nanocrystal - nanoclay reinforced PLA composites

In this study, the synergic effects of cellulose nanocrystal and nanoclay on the biodegradation and migration behavior of composite films based on polylactic acid (PLA) were investigated. PLA and PLA-based nanocomposite ﬁlms containing different loads of cellulose nanocrystal and nanoclay (0, 3 and...
