| Summary: | The idea of using a hybrid nanofiller comprised of two or more filler materials with different dimensionality can lead to a strong synergistic effect, surpass the performance of the individual filler and achieve its highest potential for improving the performance of nanocomposites. In this research, CNT/CNC hybrid filler was prepared by mixing the 6 w.t% of CNC with 0.2 g, 1.2 g, 2.2 g, 3.2 g, and 4.2 g of carbon nanotubes, respectively. The hybrid nanofiller produced was labeled as 0.2 CNT/CNC, 1.2 CNT/CNC, 2.2 CNT/CNC, 3.2 CNT/CNC, and 4.2 CNT/CNC. Subsequently, the CNT/CNC hybrid nanofiller was added as the reinforcement in 5 w.t% of polyvinyl alcohol (PVA) matrix to produce the CNT/CNC/PVA nanocomposite films using the solvent casting method. The CNC/CNC hybrid filler was characterized using viscometer and stability test while the CNT/CNC/PVA nanocomposite films were characterized using optical microscope (OM) and field emission scanning electron microscope (FESEM). The result showed that the stability of the hybrid filler could be sustained in one phase for up to 5 months. The highest viscosity of hybrid filler was at 4.2 g CNT/CNC hybrid nanofiller with 193.0 centipoises, cP. The morphology of CNT/CNC/PVA nanocomposite films from optical microscope and field emission scanning electron microscope (FESEM) revealed homogenous dispersion of hybrid nanofiller within the PVA matrix, and demonstrated the viscosity became higher due to high amounts of CNT. In conclusion, CNT/CNC can be an effective hybrid nanofiller for PVA matrix reinforcement for flexible, robust, high-performance nanocomposite. |
