Mechanical and Sorption Indices of ZnO-rGO Hybrid Filled Natural Rubber Nanocomposites: Olu Ekebafe¹; Emeka Nworie²; Hauwa Mahmud²; Stanley Omorogbe³; ¹University of Lagos; ²Auchi Polytechnic; ³Rubber Research Institute of Nigeria
    The assessment of zinc oxide – reduced graphene oxide hybrid filler in natural rubber was studied. The modified Hummers’ method was used to prepared the graphene oxide (GO) from which the reduced graphene oxide (rGO) was synthesized and hybridized with zinc oxide in a two-step process. The resulting ZnO/rGO hybrid filler was characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrophotometry (FTIR), thermogravimetric analyzer (TGA), and X-ray diffraction (XRD). The natural rubber/ZnO/rGO composites were produced by compounding based on formulations using a two-roll mill. The performance of the hybrid filler in the natural rubber composites was carried out by assessing the tensile properties, Hardness test, compression set, abrasion resistance and sorption properties in different solvents. The mechanical properties showed that NR/ZnO/rGO nanocomposite exhibited improved mechanical properties. The mole percent results of the solvents for the hybrid filled composite when compared with the control showed a critical sorption decrease attack.
