Abstract

A facile and universal approach is reported for the preparation of silica particles of various mesostructures based on the self-assembly of amphiphilic precursor polymers in water and subsequent condensation. Depending on the hydrophilization degree of hyperbranched polyethoxysiloxane, various silica morphologies including mesoporous particles, hollow nanospheres and ultrasmall particles with high application potential are fabricated.
