摘要: Nanosized silica and functionalized spherical particles have typically been made by complex methods, which were then used as template materials to fabricate nanostructured materials. However, in a simple one-step hydrolytic co-condensation process, we synthesized various sizes of nano/micro hard spheres network polysilsesquioxanes, similar silica, narrow size distribution from heterogeneous mixtures organomethoxysilanes, surfactants, water, ammonium hydroxide solution. The the polysilsesquioxanes could be controlled nanometer micrometer adjusting changing organomethoxysilane composition, molar ratio, catalyst concentration. resulting monodisperse possessed surface organic functional groups having properties applications found particles. polysilsesquioxane characterized scanning electron mic...
