Abstract: IntroductionA translucent UV protecting poly (methyl methacrylate) (PMMA)/TiO 2 nanocomposite has been fabricated using anatase TiO 2 nanoparticles by solution method.The myristic acid capped titania nanoparticles were synthesized via a simple sol-gel method, involving hydrolysis of titanium tetra isopropoxide (TTIP).So prepared nanoparticles were characterized by ultraviolet-visible (UV-Vis), photoluminescence (PL), fourier transform infrared (FTIR) and RAMAN spectroscopy.Morphology was studied with scanning electron microscope (SEM) and transmission electron microscope (TEM).Crystal phases were analyzed by X-Ray diffraction (XRD) measurements.The BET surface area was temperature dependant.% wt.loss was found to be about less than 6%.Similarly, the TiO 2 / PMMA nanocomposites were characterized by above tools.This nanocomposite film was tested for UV-shielding application via prevention of photo-chemical reaction between silver nitrate and Pyrrole under UVC irradiation.The films used for the shielding purpose were further analyzed by UV-Vis absorption and IR spectroscopy and by scanning electron microscope (SEM) to understand the effect of Pyrrole vapors on the film.The nanocomposite with ≤ 1.0 wt % of TiO 2 showed improved thermal stability, high see through and optimum UV-shielding efficiency in the present case.
