摘　　要：How to improve the stability and processability of organic-inorganic hybrid perovskite quantum dots(OHPQD)is an important topic in recent research.In this work,the stability and machinability of OHPQD were improved by blending with PU elastomer.The CsPbBr_(3)-PU composites can be achieved easily by pouring molding process with rather excellent humidity and thermal stability.The tensile strength of 14MPa and elongation of 580%at break of PU/CsPbBr_(3) elastomer composites with self-repair properties were obtained,which was attributed to the introduction of disulfide bonds.It lays a foundation for the application of OHPQD.
