Abstract
Fiber reinforced polymer composites are suitable for outdoor applications. The present study focuses on the development of polymer composite coating for composite substrate. The main aim of the study is to fabricate and characterize the polymer composite coating using single and hybrid nanofillers for oil palm empty fruit bunch (OPEFB)/recycle polyvinyl chloride (rPVC) composites. The polymer composites coating based on bio-epoxy composite was fabricated using different types of filler which are silica nanoparticles, graphene nanoparticles and carbon black nanoparticles at 0.5%,1%,1.5% and 2%.The performance of the coating was evaluated by water contact angle and water absorption test. In addition, the flexural property of epoxy composite coating on the OPEFB/rPVC was evaluated. It was found that incorporation of 2% of nanofillers can increase the water contact angle and minimize the water absorption of epoxy coating .2 % of graphene increase the water contact angle of epoxy coating from 56.7° to 73.2° and shows lower water absorption than epoxy coating. For hybrid nanofillers coating, carbon black and graphene enhance the performance of single nanofillers with ratio 1.5CB/0.5G which increase the water contact angle up to
82.2° which close to hydrophobic property. The flexural test shows that highest mechanical properties was obtained by 1.5G/0.5CB with flexural modulus 4,10177 GPa and flexural strain 3.23% meanwhile 1.5G/0.5 SiO2 has the highest flexural strength with value 56.47MPa.
