有机金属卤化物钙钛矿半导体/介孔聚乳酸基复合膜器件的压电性能—超声波振动的影响
发布时间：2021-01-28 12:47
合成是引入和推进功能材料或设备不同特性的常用方法。随后,有各种技术,结合两种或多种材料,形成一个统一的多功能/复合系统。虽然混合有机金属卤化物环丙基（OMHPs）主要被探索为照片或照片增强应用,无论是时间,位置或光有限,他们显示了多功能性,当系统地与其他材料混合。在这个工作中,采用溶胶凝胶法和垂直超声辅助基底振荡（UVPT）的工艺,来提高聚乳酸（PLA）/三碘化甲基铅胺（MAPbI3）钙钛矿复合薄膜的电活性,然后将这种薄膜应用于制备基于可弯折基底的机电和压电能量收集器中。首先,制备了半导体锡（iv）氧化物电纺纳米纤维（SnO2 NF）分散液,与聚L乳酸（PLLA）、多金丁氟化物（PVDF）的聚合物溶液适当混合,最后通过系统UVPT工艺转化为薄中孔复合薄膜结构。利用场发射扫描电子显微镜（SEM）、拉曼光谱、傅立叶传输红外光谱（FTIR）、X射线衍射（XRD）和电子分散光谱（EDS）,对所得结构进行了研究和验证。其次,MAPbI3随后通过基板的垂直超声波振动渗透到多孔复合支架中,然后添加其他功能层来完成设备结构。MAPbI<...
