Effects of silane surface treatment of cellulose nanocrystals on the tensile properties of cellulose-polyvinyl chloride nanocomposite

Cellulose nanocrystals (CNC) from mengkuang leaves (Pandanus tectorius) were investigated as potential reinforcement in poly(vinyl chloride) (PVC) matrix. The surface of CNC was modified with silane coupling agent to improve filler-matrix adhesion. Solution casting method was used to prepare PVC nan...
