摘要：

Polymer/mica nanocomposites of styrene or methyl methacrylate have been prepared by emulsion polymerization. For the polymer/mica nanocomposites, the mica was dispersed individually in water, and we found that they were adsorbed on the surface of monomer droplets. Polymer/mica nanocomposites were obtained by adding an aqueous dispersion of layered silicate into the polymer emulsion. X-ray diffraction (XRD) and FTIR spectra were used to characterize the structures of the nanocomposites. The degree of dispersion of these nanocomposites were investigated by using a transmission electron microscopy (TEM). Furthermore, the thermal and mechanical properties of polymer/mica nanocomposites were determined by using thermogravimetric analysis (TGA), differential scanning calorimeter (DSC), and dynamic mechanical analysis (BMA). The increased tan 5 of the obtained nanocomposites is ascribed to the fine dispersion of mica particles into the polymer matrix. POLYM. COMPOS., 30:351-356, 2009.
