Due to the brittleness and scarcity of ITO,current ITO transparent electrodes cannot meet the requirements of flexible optoelectronics.PEDOT may exhibit high electrical conductivity and optical transmittance.It is a good candidate to replace ITO to fabricate flexible transparent electrodes at low cost.However,PEDOT is neither fusible nor soluble.It is difficult to convert virgin PEDOT to thin films.Many methods have been developed to convert EDOT monomer to PEDOT film on substrates directly.Of them,in situ synthesis of PEDOT coating by depositional polymerization of EDOT in solution has shown advantages over others.To optimize PEDOT coating synthesized by liquid phase depositional polymerization and fabricate transparent electrode from the coating,the effect of solvent on the molecular structures and optoelectronic properties of the synthesized PEDOT were investigated;also,the variation of the sheet resistance with VUV irradiation was monitored.

从早期的有机电子,分子电子到印刷电子,已经有15年的研发历史了。大家所关心的问题是印刷电子的出路在那儿,什么时候才能量产。本文将回顾总结印刷电子材料及器件在学术界的研发进展,及各种工艺的优化对器件性能的提高,从而找出印刷电子产业化需求和可能的解决方案。不论是用全印刷还是复合式生产工艺,印刷电子应该在产品中得到应正和完善。
印刷电子技术相较传统硅基微电子技术,所需工序少、能耗低,可实现大面积、柔性化,基材适应性广。而喷墨打印作为一种“非接触”印刷方式,对墨水粘度要求较低,无需制版,喷印图案可通过计算机精确控制,节约成本,是近几年文献报道较多的印刷方式[1]。导电墨水是构成喷印导电图案的重要组分,其中银导电墨水电阻率较低且具有较高的稳定性,在导电墨水中应用广泛[2,3]。
