Modulus and thermal properties of free standing PMMA/TiO2 nanocomposite films

Abstract

TiO2 nanopowder (0-20 w%) has been introduced in the PMMA matrix using the single step of sonication method to produce the PMMA/TiO2 nanocomposite films in the free standing form. The PMMA and TiO2 solution were mixed in the sonication bath. The effects on Tg, thermal degradation and also modulus of the PMMA/TiO2 nanocomposites films were investigated. The properties of the nanocomposite films were depending on the dispersion of TiO2 nanopowder in the PMMA matrix. The results of differential scanning calorimetry (DSC), thermo gravimetric analysis (TGA), and dynamic mechanical analysis (DMTA) were discussed in this paper.
