悬浮聚合的改革探索:钙钛矿聚苯乙烯微珠的制备及其荧光稳定性能探究
Exploration of Suspension Polymerization:Preparation and Fluorescence Stability of Perovskite Polystyrene Microbeads
摘要
Abstract
Organic-inorganic lead halide perovskites,known for their numerous outstanding optoelectronic properties,have garnered significant interest among researchers and hold promising applications across various advanced optoelectronic devices.However,perovskites suffer from poor stability and are highly susceptible to factors such as light,humidity,and polar solvents.Consequently,enhancing their fluorescence stability remains a focal point of current research.Building on the foundation of the undergraduate suspension polymerization experiment in polymer chemistry,this study introduces an undergraduate-led polymer science experiment titled"Preparation and Fluorescence Stability of Perovskite Quantum Dots Encapsulated in Polystyrene Microbeads".This strategy combines polymer and perovskite materials,encapsulating organic-inorganic perovskites within polystyrene microbeads using a swelling-shrinkage strategy to form hybrid fluorescent microbeads.This approach not only enhances the stability of the perovskite materials but also broadens the applications of products from polymer science experiments.Additionally,employing the swelling-shrinkage strategy as a vanguard for cutting-edge research in this field not only aids undergraduates in understanding experimental principles but also greatly stimulates their interest in scientific inquiry.By translating cutting-edge research into an experimental teaching reform model for undergraduate education,students'experimental design capabilities,innovation skills,and overall quality have been effectively developed.关键词
