MANUFACTURING METHOD OF PEROVSKITE FILM, COMPOSITION FOR MANUFACTURING PEROVSKITE FILM, AND DISPLAY DEVICE

A manufacturing method of a perovskite film and a composition for preparing the perovskite film. The manufacturing method of the perovskite film comprises a step of manufacturing a first mixed solution, a step of manufacturing a second mixed solution, a low pressure distillation step, a coating step, and a drying step. The technical effect of the present disclosure is to provide the manufacturing method of the perovskite film and the composition for manufacturing the perovskite film, wherein the perovskite film comprises components of a metal halide and an organic halogen salt to adjust absorption wavelengths and emission wavelengths by modulating components and concentration of each component and makes the perovskite film have a higher transmittance in the visible light band. When ultraviolet light illuminates the perovskite film, the perovskite film can produce visible light due to photoluminescence effect of the perovskite material in the perovskite film, thereby achieving display effect.

ABATING UNWANTED EMULSION POLYMERIZATION DURING EXTRACTIVE DISTILLATION OF CONJUGATED DIENE MONOMERS

Inhibitor compositions for abating undesirable emulsion polymerization during processing of hydrocarbon stream laden with reactive vinylic monomers are provided.
