Latest Patents

Rui-Xuan Dong's latest patents include a groundbreaking invention titled "Polymeric polymer containing poly(oxyethylene)-amine and application thereof to preparing silver nanoparticle." This invention describes a polymeric polymer that is prepared from poly(oxyethylene)-amine and a linker, such as poly(styrene-co-maleic anhydride) (SMA) or dianhydride. The polymeric polymer can chelate silver ions and reduce them to silver atoms, resulting in nanoparticles that are well-dispersed without the need for additional reducing agents. The solution can achieve more than 30% solid content of nanoparticles without aggregation, and the prepared silver nanoparticles exhibit both hydrophilic and hydrophobic properties, making them compatible with various polymers.

Another notable patent is "Oil-dispersible composite of metallic nanoparticle and method for synthesizing same." This invention provides an oil-dispersible composite of metallic nanoparticles, primarily including metallic nanoparticles and an oily polymeric polymer such as polyurethane (PU). The oily polymeric polymer acts as a carrier for the metallic nanoparticles, ensuring uniform dispersion. In this method, metallic ions are first chelated by the oily polymeric polymer and then reduced into nanoparticles, resulting in a composite with particle sizes ranging from 5 to 100 nm.
