Polymer/metal-oxide hybrid dielectric materials are considered to be a key element for use in OFETs owing to the unique properties of organic dielectrics with those of the inorganic counterparts. Because, the high-k filler lends a high capacitance, and the flexible matric endows the dielectric with good dispersability and film-forming feasibility. The most widely used metal oxides as high-h filler as TiO₂, ZrO₂ which have high dielectric constant (k) and large band gap. However, because of their metal alkoxide’s high reactivity, it is extremely tough to prepare colloidally stable nanoparticles via sol-gel process. In this study, we presented a novel sol-gel-based process for preparation of colloidally stable TiO₂, ZrO₂ polymer hybrid nanoparticles using amphiphilic crosslinked polymers.
