随着器件小型化的需要以及分子器件的发展,基于纳米及亚微米尺度的分子材料近十年来备受关注.一维纳米结构具有本征各向异性,有利于电荷传输,是研究电子传输行为的理想体系.通过静电纺丝能够快速大量地制备聚合物纳米纤维,其孔隙率高、比表面积大,是当前一条行之有效的、重要的制备光电功能聚合物一维纳米结构的路线.本文详细阐述了通过静电纺丝技术制备光电功能聚合物纳米纤维及其在有机场效应晶体管、气体传感器和电化学传感电极等方面的应用研究进展,并进一步提出了该领域的研究前景及尚待解决的问题,同时扼要介绍了模板法、自组装法和蘸笔印刷等其他常用的制备光电功能聚合物纳米纤维的方法.
With the need for miniaturization of devices and the development of molecular devices, molecular materials based on nanometer and submicron scales have drawn much attention in recent ten years.It has the intrinsic anisotropy of one-dimensional nanostructures, which is conducive to charge transport and electron transport behavior Of nanocomposites.Polymer nanofibers can be rapidly and massively prepared by electrospinning, which has high porosity and large specific surface area, and is an effective and important route for the preparation of one-dimensional nanostructures. In this paper, the progress in the application of electrospun functional polymer nanofibers by electrospinning and their applications in organic field effect transistors, gas sensors and electrochemical sensing electrodes are described in detail, and the research prospects in this area are further discussed. Solve the problem, at the same time, briefly introduced the template method, self-assembly method and dipping pen printing and other commonly used methods for the preparation of photoelectric functional polymer nanofibers.
