Core/shell titanium dioxide (TiO2) nanoparticle/poly(Acrylamide-2-Acrylamido-2-methylpropane sulfonic acid) [P(AM-AMPS)] nanocomposite was successfully synthesized via in situ emulsion polymerization. TiO2 nanoparticles were firstly modified by silane coupling agent, 3-(Triethoxysilyl) propyl Methacrylate (MPS), to increase the dispersibility of TiO2 nanoparticles into the polyacrylamide matrix. The core/shell TiO2/polyacrylamide nanocomposite was then synthesized by in situ emulsion polymerization. The MPS-modified TiO2 nanoparticles and the synthesized core/shell nanocomposite were characterized by Fourier transform infrared spectra (FTIR) and X-Ray Diffraction (XRD). The results showed that MPS coupling molecules was chemically bonded on the TiO2 nanoparticles surface. According to XRD patterns the copolymer composite was formed.
