Sažetak
Stable dispersions of nanosilica in size between 8 and 11 nm were coated with tert-butyl acrylate polymer by in situ polymerization of monomer adsorbed on the particles in 2-propanol. The system was developed for usein the encapsulated inorganic resist technology. To achive a high coating efficiency, silica was first modified with the 3-(trimethoxysilyl)propylmethacrylate (MPS)coupling agent at two different degrees of grafting. The presence of the bound MPS agent and of the polymer at the silica surfacewas determined by the attenuated total reflection infrared spectroscopy, while the amounts bound were assessed by the thermogravimetric analysis. Under studied conditions, the encapsulation efficiency was governed by the degree of MPS grafting and by initial concentration of the monomer. Finally, the dissolution rate of these particles in aqueous base, a key parameter in photoresist application, was drastically reduced with increasing amount of grafted tert-butyl acrylate polymer at the silica surface.
