Abstract

Usage of plant source-based stiff fillers as reinforcement material in polymer composites has attracted significant interests of researchers during last few decades. The crystalline parts of the semicrystalline cellulose chains represent the most highly potential bio based reinforcing agents for polymers. This paper covers the extraction of cellulose nanocrystals (CNCs) from commercial microcrystalline cellulose (MCC) and their polylactic acid (PLA) nanocomposite films preparation by solvent casting. The nucleation effect of CNCs on PLA matrix crystallization was investigated. The production of biodegradable nanocomposites based on cellulosic biomass waste suggests the possibility of using these new bio-nanocomposites in industrial and environmental friendly applications..
