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

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.
