Improving the Lifetime of CsPbBr₃ Perovskite in Water Using Self-Healing and Transparent Elastic Polymer Matrix.

ABSTRACT: This study developed a simple and efficient strategy to stabilize inorganic halide perovskite CsPbX₃ at high relative humidity by embedding it into the matrix with elastic and self-healing features. The polymer matrix has a naturally hydrophobic characteristic of n-butyl acrylate segment (n-BA) and cross-linkable and healable moiety from N-(hydroxymethyl) acrylamide segment (NMA). It was chosen due to the provisions of both a surrounding protective layer for inorganic perovskite and elastic, as well as healing ability to the whole organic-inorganic composite. This fabricated CsPbBr₃/PBA-co-PNMA composite was demonstrated to stably persist against the suffering from hydrolysis of perovskites when exposed to a high moisture environment. The P
