在印刷电子工业中，为了生产适当低电阻（< 0.015 Ω cm）的导电层，PEDOT：PSS溶液作为透明导体是有吸引力的。湿膜目前使用常规对流烘箱在120-140摄氏度的温度下加热几分钟。近红外（NIR）辐射固化显示出将最小干燥时间从常规烘箱中的240 s（给出0.014 Ω cm）减少到2 s（给出0.011 Ω cm）。在这里，我们表明是PEDOT：PSS本身的NIR吸收引起快速固化，这限制了所使用的NIR的能量密度。(C)2014由Elsevier B. V.出版
In the printed electronics industry, in order to produce conducting layers of suitably low resistance (< 0.015 Omega cm) PEDOT: PSS solutions are attractive as transparent conductors. The wet film is currently heated using conventional convection ovens at temperatures of 120-140 degrees C for several minutes. Near infrared (NIR) radiation curing is shown to reduce the minimum drying time from 240 s in a conventional oven (giving 0.014 Omega cm) to 2 s (giving 0.011 Omega cm). Here we show it is the NIR absorbance of the PEDOT:PSS itself that gives rise to the rapid curing and this limits the energy density of NIR used. (C) 2014 Published by Elsevier B.V.
