Abstract

The fabrication of individual plastic micro-objects that follow an elaborate design and are copies of nanoporous inorganic morphotypes was investigated. The key feature of this approach was 'precision shape transfer polymerization', from individual objects of MCM-41 mesoporous silica to hybrid nanocomposites of identical shape and, plastic micrometre-sized objects. It was observed that the systematic variation of silica-precursor concentration, pH and surfactant nature, enabled the formation of controlled shapes such as gyroidal, cylindrical and tubular. It was shown using TEM images of the nanocomposite and of silica, that the original periodic structure of silica was retained and that the polymer was formed within silica mesopores.
