In this research, we used a sol-gel process to prepare UV-curable antiglare coatings. First the inorganic monomer tetraethoxylsilane was formed into colloidal silica by hydrolysis and condensation reactions. Then, added the couple agent 3- propyl methacrylate and surfactant fluoroalkylsilane (13F) to modify the colloidal silica. Finally, organic monomer dipentaerythritol hexaacrylate were added to form hybrid material.

In this thesis, monomer with unsaturated double bond was firstly synthesized byreacting acryloyl chloride with bifunctional monomer. Such synthesized monomer ormonomer with initial unsaturated double bond was used to prepare linear polymericmaterials by free radical polymerization. A series of new degradable space polymerswith acylamino bond were subsequently synthesized using diisocyanate as thecross-linker.
