摘要
Polylactic acid (PLA) is an eco-friendly biodegradable plastic and mainly used as food packaging materials and 3D printing filaments. In this study, the physical properties of PLA composites filled with cellulose nanocrystal (CNC), an environmentally friendly natural filler, were investigated. The PLA/CNC nanocomposites were prepared by melt mixing and compression molding. The tensile properties, impact strengths and thermal properties of the PLA/CNC nanocomposites with different CNC content were measured. As the content of CNC increased, the crystallinity, tensile strength and tensile modulus of the nanocomposites increased, but the glass transition temperature, cold crystallization beginning temperature and elongation at break decreased. Impact strength was the highest at the CNC content of 1 phr.
