| Abstract: | Poly （N-isopropylacrylamide） （PNIPAM） microspheres are prepared by reverse suspensmn polymerization technique. Then oxide silica particles gradually deposited on the microhydrogel via hydrolysis and condensation of tetraethoxysilane in ammonium hydroxide medium, with PNIPAM as micro-reactor. In this way, a series of PNIPAM/SiO2 composite microspheres with different surface morphology are prepared. These composite microspheres are investigated by scanning electron microscopy, Fourier transform infrared spectrometer and thermogravimetric analysis, respectively. |
