摘　　要：聚(3,4-乙撑二氧基噻吩):聚(苯乙烯磺酸)(PEDOT∶PSS)由于兼备优良的导电性和透光率,被广泛用于透明功能性薄膜的制备,可作为空穴传输层或直接用作电极,运用到有机光伏器件(OPV)、有机场效应晶体管(OFET)、有机发光二极管(OLED)等薄膜器件的结构中,部分实现了氧化铟锡(ITO)薄膜的替代。常见的溶液成膜工艺是旋涂法,这种工艺操作较为简便,但原料利用率低,并且难以大面积均匀制备及图案化制膜,不利于规模化生产和推广。近年来,喷墨打印制膜技术得到人们越来越多的关注。由于喷墨打印制膜技术可在多种基底上快速、高效地制备均匀大面积薄膜,并可轻易地实现各种精细图案化的制作,可溶液加工,更与卷对卷加工技术兼容,因此能够很好地节约原料,降低能耗和制作成本。目前已被广泛应用于有机电子学各个领域,特别是在制备柔性器件方面,展现出独特优势。本文对基于导电聚合物PEDOT∶PSS的喷墨打印工艺进行了系统的阐述,对其制膜、图案化及其电子器件应用等相关研究作了较为全面的总结,并展望了其应用前景,对于更为全面、深刻地理解和推动喷墨打印制膜技术在有机电子学领域的应用具有重要的指导和借鉴意义。Poly（ 3,4-ethylened ioxythiophene） ： poly（ styrene sulfonicacid）（ PEDOT ∶ PSS） has been widely investigated as transparent conductive films due to its superior conductivity and transmittance. Films made from PEDOT ∶ PSS have high optical transparency and excellent electrical conductivity; therefore they can be directly used as transparent electrodes or hole transport layers for organic photovoltaics（ OPVs）,organic field effecttransistors（ OFETs）, organic light-emitting diodes（ OLEDs）, etc. Owing to the superior optoelectronic performance and excellent flexibility,they are promising alternative candidates for indium tin oxide（ ITO）transparent electrodes. Spin coating is a ubiquitous method for film formation because of the facility and simplicity. However, wastage of rawmaterials and difficulty in large-area patterning severely restrict the extensive application of spin coating in film preparation. In contrast,inkjet printing is currently the most promising technology for the film forming due to its unique advantages,such as solution-processibility,material saving,lowcost and compatibility with roll-to-roll technique. Furthermore, it is capable of rapidly and efficiently preparing large-area thin films with various patterns on different substrates,holding great promise in organic electronics especially for flexible electronic devices. This reviewsummarizes recent advances in depositing PEDOT ∶ PSS films via inkjet printing,and discusses further the prospects and challenges posed in this research field.
