Abstract

Nypa Fruticans fiber (NFF) was used as filler in polylactic acid (PLA) and recycled low density polyethylene (rLDPE) biocomposites. The biocomposites were prepared by using a Brabender Plasticorder EC Plus. The effects of NFF content and Ultra-Plast TP01 (TP01) on the tensile properties and morphology were investigated. The effect of NFF content decreased the tensile strength and elongation at break of biocomposites, but increased Young’s modulus. The compatibilization of NFF and PLA/rLDPE biocomposites was improved with addition of Ultra-Plast TP01 as compatibilizer. It was found that the tensile strength and Young’s modulus of biocomposites with TP01 higher than biocomposites without TP01. The resulting FTIR spectra of biocomposites with TP01 showed the change in hydrophilic NFF to become hydrophobic. Furthermore, the morphology study of biocomposites indicated that the presence of TP01 enhanced the interfacial interaction between NFF and PLA/rLDPE matrix.
