摘要
聚(3,4-乙烯二氧噻吩)∶聚(苯乙烯磺酸)(PEDOT∶PSS)是一种水溶性导电高分子体系,具有易加工、高透光率及柔韧性等优点,但其应用范围仅限于作为电子器件的柔性电极材料。为了进一步扩大PEDOT∶PSS的应用范围,将无机纳米材料引入该体系实现材料的多功能化是较为有效的方法。本文首先介绍了PEDOT∶PSS/无机纳米复合材料最常用的四种制备方法,即原位法、共混法、自组装法、插层复合法,分别介绍了每种制备方法的原理和特点,并阐述了研究人员对复合材料的结构设计思路及引入的无机相对材料性能的影响。随后,综述了PEDOT∶PSS/无机纳米复合材料在传感器、太阳能电池、超级电容器、热电发电机等领域中应用的最新进展。最后指出了目前在PEDOT∶PSS/无机纳米复合材料的研究中面临的挑战,并对该材料的研究方向和发展趋势进行了展望。
The complex of poly(3,4-ethylenedioxythiophene)∶poly(4-styrenesulfonate)(PEDOT∶PSS)is a water-soluble conducting polymer system with many advantages such as easy processability,high transmittance and flexibility.Its application,however,is only limited as flexible electrode material in some electronic devices.To solve this,introducing inorganic nanomaterials into PEDOT∶PSS complex to realize multifunctional materials is a relatively effective method to further expand its application.In this review,four most commonly used strategies to prepare PEDOT∶PSS/inorganic nanocomposites,including in-situ method,blending method,self-assembly method and intercalation method are summarized at first.Following this,each of the methods is detailed with their mechanism and experimental features,and the structural design of the nanocomposites as well as the structure-property relationships that affected by introduced inorganic nanofillers are also elucidated.Then the latest research progress of applications in sensors,solar cells,supercapacitors,thermoelectric generators of PEDOT∶PSS/inorganic nanocomposites are reviewed.Finally,the existing challenges in PEDOT∶PSS/inorganic nanocomposites studies are pointed out,and the future perspectives are provided for the research direction and potential progress and trends of these materials.
