| Abstract | ||
| Comparison for the optical energy gap between pure PMMA , PMMA-TiO2 micro composites and PMMA-TiO2 nano composites have been investigated under uv – radiation , the effect of time irradiation (0,6,12,24,48,72,96 and 120) have been studied for these specimens to study the photic stability .The results show that the photostability of the PMMA-TiO2 nanocomposite is higher than that of the pure PMMA and PMMA-TiO2 micro composite under UV-light irradiation. | ||
