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 CsPbBr3−PU composites can be achieved easily by pouring molding process with rather excellent humidity and thermal stability. The tensile strength of 14 MPa and elongation of 580% at break of PU/CsPbBr3 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.
