Variation of Refractive Index of PMMA with temperature an d different doping % of Tio 2
Journal Title: International Journal of Scientific Research and Management - Year 2015, Vol 3, Issue 10
Abstract
A simple and reliable method of measuring the refractive index of thin film is reported in the present paper. In this work, an experimental approach of Digital Abbe Spectrometer was used for measuring refract ive indices of pur e and doped PMMA at different wavelengths in the visible region. R efractive indices measurements at wavelengths of 405 , 458, 492.2, 499, 546, 589, 632.8, 659.2, 670.2 nanometres were taken of Titanium di Oxide doped Poly (methyl metha acrylate) PMMA films. Also we explain with th e help of graph refractive indices of PMMA increases with increasing doping percentage (0.0001%,0.0005%,0.001%,0.005%,0.01%,0.05%) & we compare the refractive indices of un annealed and annealed polymer of doped PMMA at different temperature s (40°C, 60°C, 80°C, 100°C)
