Abstract

This study is to investigate the influence of sol volume and heating temperature on TiO2 sol-gel coating.Many research had been carried out on TiO2 but research that focuses on Brookite is rarely been done.The sol volume produced by using the sol-gel method and then the solutions deposited on the surface of microscope glass. The amount of sol volume is different.After all, microscope glass coated with TiO2,undergo heat treatment at different temperature.The result of TiO2 thin films depends on how it being prepared and a parameter that involved in the whole processes.Thin films sample analysed using XRD and SEM machine to see the phase and morphology of the sample.The thin films coated with different volume of sol and heated on different temperature shows a different morphology and phases,the more sol volume deposited on the glass,the thickness of coating are thicker while in term of temperature the structure of thin films crystallinity better at the higher temperature.At 2 spin,the grain size increased when heating temperature increased from 23.97 nm (200 ͦC) to 47.98 nm (400 ͦC).At 4 spin,thin film increasing when heating temperature increased from 3249.0 nm to 680.92 nm.At 300 ͦC,film thickness increased when number of coating increased from 467.35 nm (4 coating) to 337.10 nm (8 coating).
