Self-assembled micro-nano structure cu2o particles and preparation method thereof

Abstract

The present application relates to a kind of self-assembly micro-nano structure Cu2O particle and its preparation method, self-assembly micro-nano structure Cu2O particle is the microscale sphere formed by multiple nanoscale Cu2O particle assembly, wherein, assembly utilizes the physical or chemical action force between dendritic polymer;Preparation method is: first respectively with A2 type monomer and B3 type monomer using A2+B3 method synthesis dendritic polymer, then dendritic polymer is added to polyether amine aqueous solution and forms uniform transparent reaction system, then under stirring condition, copper salt solution is added dropwise to reaction system, and continue stirring for a period of time, finally under stirring condition, ascorbic acid aqueous solution is added dropwise to reaction system, and continue stirring for a period of time, and self-assembly micro-nano structure Cu2O particle is prepared.The method of the present application is simple, and the self-assembly micro-nano structure Cu2O particle prepared has both the excellent application performance of nanoscale and the good dispersibility of microscale, and can maintain persistent stability in the use process.
