The aim of this study was to synthesize and characterize new types of silsesquioxane-based hybrid nanocomposites with self-assembling properties. Through radical polymerization of the polymeric matrix (3-(trimethoxysilyl)propyl methacrylate) that contains both methacrylate and silica phases in or without the presence of a surfactant (dodecylamine), new type of hybrid nanomaterials were obtained in which silica was dispersed in the form of domains with typical sizes in the nanometer range. The self-assembling properties of the synthesized composites have been ascribed to formation of polyhedral structures or a combination of linear, ladder, and cagelike fragments of silsesquioxane type. Such materials could find application in stone conservation and water-repellence, as well as drug delivery.
