This work aimed to obtain an optically transparent electrode based on the oriented nanonetworks of nickel in poly(3,4-ethylenedioxythiophene) polystyrene sulfonate matrix. Optically transparent electrodes are used in many modern devices. Therefore, the search for new inexpensive and environmentally friendly materials for them remains an urgent task. We have previously developed a material for optically transparent electrodes based on oriented platinum nanonetworks. This technique was upgraded to obtain a cheaper option from oriented nickel networks. The study was carried out to find the optimal electrical conductivity and optical transparency values of the developed coating, and the dependence of these values on the amount of nickel used was investigated. The figure of merit (FoM) was used as a criterion for the quality of the material in terms of finding the optimal characteristics. It was shown that doping PEDOT: PSS with p-toluenesulfonic acid in the design of an optically transparent electroconductive composite coating based on oriented nickel networks in a polymer matrix is expedient. It was found that the addition of p-toluenesulfonic acid to an aqueous dispersion of PEDOT: PSS with a concentration of 0.5% led to an eight-fold decrease in the surface resistance of the resulting coating.
这项工作旨在获得一种基于聚（3,4-乙撑二氧噻吩）聚苯乙烯磺酸盐基质中镍的定向纳米网络的光学透明电极。光学透明电极被用于许多现代设备中。因此，寻找新型廉价且环保的电极材料仍然是一项紧迫的任务。我们之前已经开发出一种基于定向铂纳米网络的光学透明电极材料。这项技术经过改进，以从定向镍网络中获得更便宜的选择。开展该研究是为了找到所开发涂层的最佳电导率和光学透明度值，并研究这些值与所用镍量的关系。品质因数（FoM）被用作在寻找最佳特性方面评估材料质量的标准。结果表明，在基于聚合物基质中定向镍网络设计光学透明导电复合涂层时，用对甲苯磺酸掺杂聚（3,4-乙撑二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）是合适的。研究发现，向浓度为0.5%的PEDOT：PSS水分散体中添加对甲苯磺酸，会使所得涂层的表面电阻降低八倍。
