Abstract

The main purpose of incorporating Nypa Fruticans (NF) into Polylactic Acid (PLA)/Recycled Low Density Polyethylene (rLDPE) biocomposites is to decrease costs and change the properties. Polyethylene–co–acrylic acid (PEAA) was used as a compatibilizer. The effect of NF content and PEAA on the mechanical properties and morphology of the biocomposites were investigated. Results show that the effect of NF content increased Young’s modulus but decreased the tensile strength and elngation at break of PLA/rLDPE/NF biocomposites. It was found that incorporation of compatibilizer (PEAA) increased the tensile strength and Young’s modulus but decreased the elongation at break of compatibilized biocomposites. Scanning electron microscopy (SEM) study of the tensile fracture surface of the biocomposites indicated that the presence of PEAA improved the interfacial interaction between Nypa Fruticans and LDPE matrix.
