Dispersion of TiO<sub>2</sub> Nanopowder in the PMMA Matrix Prepared by Sonication-Solution Casting Method

Abstract

This paper discussed on the structural properties of the PMMA/TiO2 nanocomposite films prepared using sonication-solution casting method. The structural properties of the nanocomposite films were compared by mixing the self-prepared TiO2 (~12 nm) and the commercially available TiO2 (25 nm) in the PMMA. The well dispersion of self-prepared TiO2 nanopowder was observed in the FESEM micrograph. XRD results show that the self-prepared TiO2 nanopowder decrease the crystallinity of the nanocomposite. Further, FTIR reveals that the interaction between the PMMA and TiO2 nanoparticles were detected.
