Silane Coupling

The tensile properties and morphological studies of linear low density polyethylene (LLDPE)/poly (vinyl alcohol) (PVA)/kenaf (KNF) composites with and without 3-(trimethoxysilyl) propyl methacrylate (silane coupling agent) were investigated. The composites with different KNF loading (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 composites with 3-(trimethoxysilyl) propyl methacrylate gives higher tensile strength and modulus but lower elongation at break than composites without. The presence of 3-(trimethoxysilyl) propyl methacrylate found to enhance the interfacial adhesion between LLDPE/PVA matrix and KNF fiber. Morphological studies on tensile fractured surfaces showed good adhesion between LLDPE/PVA matrix and KNF, and better dispersion of KNF for the composites with 3-(trimethoxysilyl) propyl methacrylate.

Internal Mixer

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.
