The dispersion of silica in concentrated courtelle/DMF solution was studied(Courtelle is a copolymer of 94 mol%acrylonitrile and 6 mol%methyl acrylate). It is found that the agglomeration of silica is the combined results of surface energy and surface hydrogen bonding, The dispersibility of silica is markedly improved by the addition of 3-trimethoxysilyl propylmethacrylate(>1.2%). The improvement is believed to be caused by the chemical reaction between the silane and silanol groups on silica surface, reducing the concentration of hydrogen bonding, hence the attractive forces.
