Surface Morphology of Nano-Sized Titanium Dioxide
The nanoscale materials have a large surface area for a given volume. The larger particle size has some disadvantages such as it can increase the sensitivity to defects. Thus, in this study, the titanium dioxide was synthesized using new method of sol gel assisted with the milling process to investigate its structural and surface morphology. FESEM results show the agglomeration of the particles produces the large particle size of TiO2. In the milling process, longer milling time of 6 h does not affects much on the size of the particles of TiO2, but more affects on its surface morphology of TiO2. The effect on the milling amount of TiO2 also were studied where 4 gram TiO2 shows the highest agglomeration of the sample and 6 gram TiO2 shows the smooth surface compared to others. Finally, the best structure of TiO2 was added into the PMMA to investigate the effects of TiO2 on the composite surface morphology.
