Bridged polysilsesquioxane (BPS) nanoparticles with organic-inorganic structure were synthesized by sol-gel process. BPS silane monomer has oligomeric bridging group which is urethane linkage synthesized through urethane reaction of isocyanate and OH group. Urethane-based organic polymers have excellent biocompatibility, thermal stability, durability, elasticity, and high biodegradability. In this work, self-polymerized dopamine that can briefly reacts onto the surface of various materials coated on BPS nanoparticles for glues. Also, the silane with epoxide group is easily functionalized with trialkoxysilyl group of BPS nanoparticles via hydrolysis reaction. Thermal properties of adhesive material coated BPS nanoparticles can be increased by self-polymerization or crosslinking reaction. Properties of adhesive coated BPS nanoparticles were characterized NMR, SEM, TGA and various instruments. |
