| Popis: | The synthesis of the bioceramics titanium dioxide on its template by polymethyl methacrylate to be a sample with forming TiO2/PMMA was made with sol-gel process, and its pore membrane characteristics has also been studied. Different calcination temperatures 500°C, 550°C, and 600°C were given to sample for 17 hours. This purpose themselves was to fill TiO2 fissures with PMMA on different concentrations of 0.0, 2.0 wt%, 3.0 wt%, 4.0 wt%. Template leaching technique was used to remove PMMA from samples, and it was then sequentially found of the pore size of the membrane in approximate ranges (1900 nm - 2000 nm), (860.5 nm – 1669 nm), (312.8 nm-382.5 nm), and (136.1 nm - 269.7 nm). SEM test using and fourth it has average thickness in about 6.7 nm with Ellipsometer measurement. The percentage values of titanium and oxygen atoms are found by SEM-EDX from 3.03 at.% up to 66.81 at.% and there is amount 99.99% of the sample in anatase phase forming at 550 0C with angle of diffraction is 25.410 and it was prepared by XRD measurement. |
