Silica core nanoparticles were surface-modified with MPS(3-(trimethoxysilyl)propyl methacrylate), and polymerized with thermosensitive poly(NIPAAm), foamable poly(methacryloyl toluenesulfonyl hydrazide)[poly(MATSH)] and crosslinkable MBAA(methylene bisacrylamide). Thermoreversible nanoporous hollow nanospheres were prepared by foaming poly(MATSH) followed by selective removal of SiO₂ cores using hydrofluoric acid etching. Silica nanoparticles modified with polymers and hollow polymer nanoparticles were characterized by DLS, NMR, FT-IR spectroscopies, SEM and TEM image. |
