PSS organic printed electronics chemical interactions with the ink-receiving layer (IRL) of monopolar inkjet paper substrates and coating color composition were evaluated through Raman spectroscopy mapping in (depth) and () direction, Fourier transform infrared spectroscopy (FTIR) and energy dispersive X-ray spectroscopy (EDS). Other evaluated properties of the IRLs were pore size distribution (PSD), surface roughness, ink de-wetting, surface energy and the impact of such characteristics on the electronics performance of the printed layers. Resin-coated inkjet papers were compared to a multilayer coated paper substrate that also contained an IRL but did not contain the plastic polyethylene (PE) resin layer. This substrate showed better electronic performance (, lower sheet resistance), which we attributed to the inert coating composition, higher surface roughness and higher polarity of the surface which influenced the de-wetting of the ink. The novelty is that this substrate was rougher and with somewhat lower printing quality but with better electronic performance and the advantage of not having PE in their composite structure, which favors recycling.
通过拉曼光谱映射在（深度）和（）方向、傅里叶变换红外光谱（FTIR）和能量色散X射线光谱（EDS），评估了PSS有机印刷电子与单极性喷墨纸基材的墨接收层（IRL）以及涂料颜色组成之间的化学相互作用。IRL的其他评估特性包括孔径分布（PSD）、表面粗糙度、油墨去湿、表面能以及这些特性对印刷层电子性能的影响。将树脂涂层喷墨纸与多层涂层纸基材进行了比较，该多层涂层纸基材也包含一个IRL，但不含塑料聚乙烯（PE）树脂层。这种基材表现出更好的电子性能（，更低的表面电阻），我们将其归因于惰性涂料组成、更高的表面粗糙度和更高的表面极性，这些因素影响了油墨的去湿。新颖之处在于，这种基材更粗糙，印刷质量略低，但电子性能更好，并且在其复合结构中没有PE，这有利于回收利用。
