Abstract

In this study, the hybrid TiO2/PVA nanofiber by electrospinning technique was successfully synthesized. The TiO2 particle was prepared by sol-gel method and heated at 800°C for three hours. The size of TiO2 particle was not even and bigger. Other than that, the TiO2 particle was also agglomerate. The size of TiO2 particle was approximate 818.8 nm. The solution concentrations of PVA was prepared at various solution concentrations which were 6 wt%, 7 wt%, 8 wt%, 9 wt% and 10 wt%. All the PVA solution has been electrospin to produce nanofiber and investigate the relationship between the solution concentration of PVA and the diameter of nanofiber produced by electrospinning technique. The average diameter at the lowest concentration (6 wt%) was at 147 nm whereas at the highest concentration (10 wt%) was at 253 nm. It showed that the diameter of PVA nanofiber influenced by the solution concentration of PVA. The hybrid TiO2/PVA solution was prepared by dissolving the TiO2 particle with the PVA solution at 10 wt%. The hybrid TiO2/PVA solution was prepared at several concentrations which were 1 wt%, 3 wt% and 5 wt% and has been electrospin to produce nanofiber. It showed that as the Ti02 particle loaded in the PVA nanofiber increased, the size of the nanofiber decrease from 300 nm to 279 nm from 1 wt% to 5 wt%. The characterization was carried out by XRD, FESEM, EDX and Image J in this study.
