Synthesis of TiO2/Polymer Composite Microspheres Using Functional Porous Polymer Particle as Substrate
This study described a different nano-titania(TiO2)/polymer composite where TiO2 were uniformly deposited on the porous poly(styrene-divinyl benzene-co-maletic anhydride) [poly(st-DVB-co-MAH)] microspheres. The morphology of the composite microspheres was analyzed by scanning electron microscope and X-ray diffraction. Both the diameter of the pore and the MAH functional groups played a crucial role in controlling the structure of TiO2 shell. The rutile nanoparticles were incorporated evenly onto the surface of the porous microspheres when microspheres with pore diameter of about 146.8 nm and with surface 30 wt% functional groups (MAH) were used as substrate.
