摘　　要：基于半导体高分子功能材料的新型光电器件因其兼容性好、成本低、加工处理方便等特点逐渐走入人们的视野.加工集成高性能高分子光电器件需要用到可控图案化技术,这也将成为未来物联网、光通信、智能社会的基础核心技术.近年来,许多致力于此方面的研究取得了重要的成果.本文总结了各类高分子材料图案化技术,包括光刻法、模具诱导法、印刷法、浸润性调控组装法的技术特点,然后归纳了高分子图案化技术在场效应晶体管、光电探测器、气体传感器、电致发光二极管、光伏器件等光电器件领域的研究进展,最后对未来这一领域发展的挑战与机遇进行了展望.Optoelectronic devices based on semiconductor polymers have attracted extensive attention due to their solution processability,light weight,flexibility and low cost.The fabrication of polymer optoelectronic devices with high integration and performance requires controllable patterning technology.The past decade has witnessed the rapid development of different strategies,which focus on patterning conducting polymers with high precision and resolution.Herein,we summarized processing and patterning methods including photolithography,moulding and printing,and our patterning techniques based on the superwetting interface,which introduced a capillary force to steer the dewetting dynamics and mass transport process.The asymmetric-wettability topographical surfaces were integrated onto a 3D template by a selective modification process.For a topographical template with periodically arranged micropillars,two dewetting mechanism were allowed.We then briefly summarized the recent researches and developments of these polymer patterning technologies in the fields of fieldeffect transistors,photodetectors,vapor sensors,light-emitting diodes and solar cells.Finally,an outlook is provided with regard to the concerns and challenges for the future study on the mechanism and the integrated optoelectronic devices of conducting polymer in this field.We speculate that this article could serve as a trigger for future development in the fields of polymer functional materials pattern.
