摘　　要：首次采用静电纺丝技术,在电场作用下,原位合成了超稳定钙钛矿(CH3NH3PbBr3)/聚苯乙烯(PS)纤维薄膜,尽管钙钛矿CH3NH3PbBr3在PS中的掺杂量只有2%(质量分数),但在薄膜中确切检测到了其明显且均匀的荧光信号.由于PS纤维强疏水性及对钙钛矿的包覆作用,极大提高了复合薄膜的耐水性能,同时通过光谱学和形貌学等表征手段,研究了静电纺丝方法及高聚物在提高钙钛矿晶体水稳定性的内在机理,为高稳定钙钛矿复合薄膜的制备及应用提供了一种行之有效的技术方案.For the first time,electrospinning technology was used to synthesize ultra-stable perovskite(CH3NH3PbBr3)/polystyrene(PS)fiber film in situ under the action of electric field,although the doping amount of perovskite CH3NH3PbBr3in PS was only 2%.However,its distinct and uniform fluorescence signal was detected exactly in the film.Due to the strong hydrophobicity of PS fiber and the coating effect on perovskite,the water resistance of the composite film is greatly improved.At the same time,the electrospinning method and high polymer are studied in detail through characterization methods such as spectroscopy and morphology.The internal mechanism of improving the water stability of perovskite crystals provides an effective technical solution for the preparation and application of high-stability perovskite composite films.
