| Summary: | Electroless deposition on natural fibers is one of the modification methods in improving the properties of the fibers thus increasing its specific strength, electrical and electromagnetic properties. The utilization of natural fibers in polymer composite can reduce dependency on those synthetic type. In addition, the source of natural fibers are abundant and most importantly renewable and cheap. With proper surface modification, the drawbacks of the natural fibers such as high moisture absorption and poor surface interaction with the matrix is expected to be improved. In this study, kenaf fiber was used, it was firstly undergo alkaline treatment before being activated in deep eutectic solvent (DESs). After heat treatment the surface activated kenaf will be deposited with Ni alloy in a plating bath. The coated kenaf fiber will be finally made into polymer metal composites using epoxy resin as the matrix. The flexural and impact properties has increased with the deposition of Ni. However, the prolonged soaking and higher alkaline concentration damaged the fiber structure and decreased both flexural and hardness value. The scanning electron microscopic was also done to analyze the surface morphology and Ni was observed presence into the composite. The X-ray diffraction analysis in addition, also detected the Ni presence in the crystalline region. |
