Tensile Properties and Morphological Studies of Kenaf-filled Linear Low Density Polyethylene/Poly(Vinyl Alcohol) (LLDPE/PVA/KNF) Composites: The Effects of KNF Loading

摘要

Tensile properties and morphological studies of linear low density polyethylene (LLDPE)/Poly(vinyl alcohol) (PVA)/kenaf (KNF) composites were investigated. The composites with different KNF loading (0, 10, 20, 30, 40 phr) were prepared using a Thermo Haake Polydrive internal mixer at 150°C and 50 rpm for 10 min. The results indicated that tensile strength and elongation at break were decreased with increasing KNF loading, whereas tensile modulus showed the opposite trend. Tensile fractured surfaces observed by Scanning Electron Microscopy showed better interfacial adhesion between LLDPE/PVA and KNF at 10 phr KNF loading.
