Research Progress of Silicone Supramolecular Materials

Due to their unique organic-inorganic structures, silicone materials with excellent thennostability, , biocompatibility, electrical insulation and gas permeability have been widely used in various fields. However, traditional silicone materials are mainly based on irreversible covalent cross-linking, thus lacking the ability of damage repair, reprocessing and recycling. In this context, silicone supramolecular materials have attracted extensive attention, and a variety of functional materials have been developed. This review outlines the recent research progress of silicone supramolecular materials with regard to their molecular design , superior properties and prospective applications. By combination with the research results of our group in this field, we summarized various types of silicone supramolecular materials, including the hydrogen bond type, metal coordination bond type, Lewis acid-base pair type, ionic bond type, and pi-pi stacking type silicone supramolecular materials. The future directions of this field are also commented.
