A novel strategy to synthesize the monodisperse superficially porous core-shell silica microspheres (CSSMs) with enlarged mesopore channels perpendicular to the particles surface using a dual-templating approach was presented for the first time. With hexadecyl trimethyl ammonium bromide (CTAB) as the template and trioctylmethylammonium bromide (TOMAB) as an auxiliary chemical to enlarge the size of...
In this study, the monodisperse large-porous silica microspheres were successfully synthesized with polymer microspheres as the templates and characterized. The functionalization of the PGMA-EDMA microspheres was carried out with TEPA to generate amino groups. Subsequently, TEOS was readily hydrolyzed to form Si-containing low molecular weight species with ammonia as a catalyst. The low molecular...
