Abstract
[Problem] An object of the present invention is to provide a composite of metal oxide nanoparticles and a silsesquioxane polymer, which can form a high-quality cured film wherein aggregation and the like of metal oxide do not occur during a curing process and the metal oxide is uniformly dispersed. [Means for Solution] Provided are: a method of producing a composite of metal oxide nanoparticles and a silsesquioxane polymer, the method comprising reacting a silsesquioxane polymer having a silanol group at a terminal, or a silane monomer with metal oxide nanoparticles having a hydroxyl group or an alkoxy group on the surface in an aqueous solvent in the presence of a phase transfer catalyst; and a composite produced by the method.
