Latest Patents

Chang-Lun Lee holds a patent for a "Method for preparing wear-resistant hybrid." This method involves several key steps: first, providing nano-silica with hydroxyl groups on its surface to react with an isocyanate-based silane to form silica with silyl groups. Next, the silica with silyl groups undergoes a hydrolytic condensation reaction using sol-gel technology to create highly bifurcated Si-HB nanoparticles with hydroxyl groups. The process continues with the reaction of a diisocyanate with a polyol to form a urethane pre-polymer. Finally, the Si-HB nanoparticles with hydroxyl groups are subjected to an addition reaction with the urethane pre-polymer and a chain-extending reagent to produce a hybrid of Si-polyurethane (PU/Si-HB), resulting in a wear-resistant hybrid of Si-polyurethane.
