Silane coupling agents basic structure

Several modifications of commercial silane coupling agents have been evaluated to search for improved bonding at the interface. These approaches attempt to use modifiers to counteract basic faults of the individual silanes. Some of these modifications include increased hydrophobic character, increased crosslinking of the siloxane structure, increased thermal stability, and ionomer bond formation to reduce shear degradation at the interface. 

Silane coupling agents exert powerful effects on the interaction potential of glass fiber surfaces, enabling the user to design either acidic or basic functionality into these reinforcing structures for polymer composites.
