| Outline of Final Research Achievements |
The dispersion of hydrophilic fumed silica in polystyrene (PS) was much improved by polymer pre-adsorption on the silica for the composite specimens produced by solvent-cast from the suspensions. The adsorption of poly(2-vinylpyridine) incompatible with PS rather than PS made the silica well dispersed in PS matrix. The inherent microstructure of fumed silica estimated as mass fractal dimension was not changed much even in the polymer matrix. When carbon black was used as solid particle, dispersion of the carbon black in PS matrix reflects its stability in a suspension state according to the characteristics of the solvents used.
