Latest Patents
Junqing Wu holds a patent for a "Method for preparing silver nano-rings." This invention focuses on a unique preparation method that utilizes polyvinyl pyrrolidone of different molecular weights as a surface-protecting agent. The process involves dissolving silver nitrate in a low molecular weight polyvinyl pyrrolidone ethylene glycol solvent under frozen conditions. This method effectively slows down the reduction of silver ions to zero-valent silver, resulting in the formation of silver nanoparticles that are coated and complexed with both low and high molecular weight polyvinyl pyrrolidone. The varying molecular weights of polyvinyl pyrrolidone influence the selective absorption of silver and the stability, which in turn affects the growth rate of silver atoms along different crystal faces. This innovative approach enhances the production of silver nano-rings, yielding products with a perfect circular shape, smooth surface, oval cross-section, and excellent crystal structure.
