The structural characteristics of silicone compounds mainly include the following aspects:
Basic structural unit: The basic structural unit of silicone is composed of silicon-oxygen chain segments, and the side chains are connected to various other organic groups through silicon atoms. This special composition and molecular structure make silicone have the characteristics of both organic and inorganic substances.
Chemical bond characteristics: The Si-O bond in silicone compounds has a covalent bond with 50% ionic bond characteristics, which makes its molecular structure stable and resistant to high temperatures. The bond energy of Si-O bonds is high, making it difficult for silicone products to break or decompose chemical bonds at high temperatures.
Physical properties: Due to the non-polarity of C-H, the intermolecular interaction force is very weak, which makes silicone materials have low surface tension and low surface energy, and strong film-forming ability. In addition, the Si-O bond length is long and the bond angle is large, which further enhances its physical stability.
