Rare earth complex modified polyurethane

A new round of national assessments shows that in the past five years, the State Key Laboratory of Rare Earth Materials Chemistry and Applications has made gratifying progress in the basic research and application of rare earth functional materials. One of them is the successful use of rare earth complexes. Polyurethane was modified.
According to reports, the research team of the laboratory systematically studied the interactions between rare earth complexes and nylons with different structures and properties and their effects on the physical and chemical behavior of the nylon body, and introduced the screened complexes into the nylon system. Through the complex coordination between nylon amide groups and rare earth ions, different nylon molecular chains are linked together, greatly increasing the molecular weight of nylon, and increasing the draw ratio of nylon melt from 100 in conventional spinning. More than 900, and successfully developed ultra-fine nylon filament filaments less than 1 denier.
It is reported that this kind of superfine nylon fiber filament is a new product with China's independent intellectual property rights, which provides a new way for the application of rare earth resources in China. The rare earth complex was dispersed nanometerly in a polymer medium by using inorganic chemistry principles such as coordination between rare earth complexes and macromolecules, intermolecular interaction, etc. The polyurethane was successfully modified with rare earth complexes. .
