Abstract: Nanosized titanium dioxide particles were engrafted with butyltitanate coupling agent and methylmethacrylate monomer, and the obtained nanocomposite was characterized by Fourier transform infrared spectra and sedimentation test. Ultraviolet-visible light spectroscopy was used to study the differences and effectiveness of the coated and uncoated titanium dioxide, respectively. The results showed that polymethacrylate chain was engrafted on the surface of nanosized titanium dioxide and the surface grafting of polymers improved significantly absorbency of ultraviolet light of the nanoparticles.
