Abstract

Internal polymeric soft templates are used for the polymerization of twin monomers (TM) to achieve nanostructured hybrid materials of desired morphology. For this purpose, oligomeric groups such as oligo(ethylene glycol) (OEG) or polymerizable ethenyl-substituents were covalently linked to the silicon atom of TMs of the 4H-benzo-1,3,2-dioxasiline type. These functionalized TMs are used in simultaneous twin polymerization in combination with the ideal TM 2,2'-spirobi[4H-1,3,2-benzodioxasiline]. Nanostructure dimension can be adjusted in the range from 2 to 20 nm by the composition of the components used in hybrid material synthesis. Inorganic/organic hybrid material disks of interpenetrating networks with hierarchical nanostructures are available by polymerization in the melt which are potentially suitable as membrane devices. Physical properties such as brittleness, transparency, electrolytic stability, and barrier properties of the hybrid material could potentially be adjusted by changing both monomer composition and monomer structure.
