There is an increased focus on the synthesis and examination of nanoporous materials with hierarchical nanostructures because they can exhibit the advantages of each of hierarchical pores with a synergistic effect and thus lead to fundamental breakthroughs that improve their properties in many applications. In this work, porous hollow nanoparticles were prepared using colloidal silica as a template. The nanoparticles were prepared by initially coating silica with 3-methacryloxypropyltrimethoxysilane and forming a shell by the polymerization of a mixture of styrene and methyl vinyl ketone (MVK) with divinylbenzene as cross-linking agent, followed by the removal of silica core by etching with hydrofluoric acid. The resulting polymeric shell was then formed porous structures by photodegrading poly(MVK) components with UV irradiation. The porous, polymeric shell was characterized by 13C NMR, FT-IR and TGA. The morphology and the size distribution was determined with FE-SEM, TEM, and DLS. |
