abstract

  • This study deals with the fabrication and characterization of polymer matrix thin films containing high content titanium dioxide (TiO2). Poly(diallyldimethylammonium chloride) (PDADMAC) membrane incorporated with different percentages of TiO2nanoparticles were prepared by solvent casting. The morphologies of the films were characterised by scanning electron microscopy (SEM), and its thermal behavior were characterised by thermogravimetry(TG). The results indicated that dense TiO2/polymer thin films can been fabricated conveniently by solvent casting from aqueous solutions of TiO2/PDADMAC when the concentrations of TiO2were lower than 40 wt%, and the thermal stability of the TiO2/PDADMAC composites were greatly improved by the addition of TiO2moieties.
