Problems solved by technology

The inventor found in the research that when the rare earth europium-DPPD-o-phenanthroline ternary complex is used in polylactic acid composite materials, the rare earth europium-DPPD-o-phenanthroline ternary complex does not work well. Dispersed in polylactic acid and ABS materials, due to the poor dispersion of the complex, it also causes poor compatibility between the components. The most direct reaction is that the glass transition temperature of polylactic acid cannot be effectively controlled. improve
In order to solve the dispersion problem of the rare earth europium-DPPD-o-phenanthroline ternary complex in polylactic acid and ABS materials, the inventor also added a compatibilizer and a dispersant in common sense. Although there is a certain effect, the effect is not good
The reason is that the rare earth europium-DPPD-o-phenanthroline ternary complex is a newly synthesized component, and the current conventional dispersants cannot disperse it well in polylactic acid and ABS materials.
