II. Structure and Characteristics

The structure of bis-glycidoxy silane coupling agents primarily consists of siloxane bonds and glycidoxy groups. Siloxane bonds provide strong chemical bonding forces, ensuring firm adhesion between the coupling agent and polymers or inorganic fillers. Glycidoxy groups, meanwhile, cross-link with hydroxyl groups on the surfaces of polymers or fillers, forming stable chemical bonds. This structure offers significant advantages in enhancing the mechanical properties, heat resistance, and corrosion resistance of composite materials.

The synthesis of bis-glycidoxy silane coupling agents mainly involves condensation methods and ring-opening polymerization methods.

• Condensation Method: Under catalysis, glycidoxy groups react with silane monomers to form bis-glycidoxy silane compounds.
• Ring-Opening Polymerization Method: Functional groups (e.g., epoxy or vinyl groups) are introduced to induce ring-opening polymerization of silane monomers, producing bis-glycidoxy silane compounds. Each method has distinct advantages and disadvantages, and the choice depends on specific application requirements.
