Here, thermoplastic natural rubber (TPNR) blend filled with polyaniline (PANi) and graphene nanoplatelets (GNPs) was fabricated via melt blending and compression moulding. The synergistic influence of including 1–5 wt% GNPs with 3 wt% PANi in nanocomposites on the mechanical via tensile test, Impedance electrical test, thermal stability via thermogravimetric analysis test and morphologic observation were examined. Inclusion of 2 wt% of GNPs increased by 62.8 % on tensile strength and 151.8 % on Young's modulus of TPNR/PANi. The highest electrical conductivity and thermal stability were achieved in the same nanocomposite composition. With a low loading of GNPs, an electrical conductivity of 2.6 E−9 S/cm was achieved which potential to be a new semi-conductive material. At this optimum content, the scanning electron microscopy micrograph revealed a homogenous distribution of GNPs in the TPNR/PANi blend as well as good matrix-filler interaction. To be practical in real application, cost-effectiveness is another important aspect to be determined. In this work, researchers evaluated the cost-performance of each system (TPNR, TPNR/PANi and TPNR/PANi/GNP) based on material costs, mechanical and electrical properties. Different general trends (positive, negative and synergistic) of cost-efficiency relationship were obtained for different material system and the priority greatly depends on their intended uses. |
