Abstract

Mechanical properties such as tensile strength, elastic modulus and elongation at break of graphite/ biopolymer composites with different particulate fractions of graphite (5 wt.%, 10 wt.%, 15 wt.%, 20 wt.%, 25 wt.%, 30 wt.% by weight percent in the composites ) were investigated. The composites showed improved elastic modulus and tensile strength with increase treated graphite weight loading by ~300% and ~200% respectively at the percolation threshold, compared with those of its neat counterpart. Meanwhile, the functional group tends to decrease in the composites with increasing filler content in which contributes to the stifness of the composites as the elongation at break of composites decline. The results implies that the mechanical properties of the composites mainly depend on dispersion condition of the treated graphite filler, crystallite structure and strong interfacial bonding between treated graphite in the biopolymer matrix.
