技术领域
本发明属于材料化学技术领域，涉及一种N型导电浆料的制备方法。
背景技术
随着智能化电子技术的发展，柔性化成为电子器件的一大发展趋势。柔性导电电极材料研究在全球范围内方兴未艾。目前市场中以共轭导电高分子为基础的多种导电浆料均为P型导电特性，包括德国Clevios生产的PH200～PH1000系列共轭高分子全有机透明导电浆料和比利时Agfa公司的OrgaCon系列的PEDOT导电油墨等。这些导电油墨显示P型导电特性，涂膜后作为空穴传输层(Comparison of performance and stability ofperovskite solar cells with CuInS2 and PH1000hole transport layers fabricatedin a humid atmosphere，Yong Zhai等，Journal of Nanoparticle Research，2017年，19卷，384)。有机光电领域中，柔性N型电极多为蒸镀的小分子化合物，之对应N型高分子导电浆料基本处于空白。高分子导电浆料的丝印工艺在制造成本和稳定性上较之气相蒸镀均有显著优势，因此，高分子为基础的N型导电涂料对柔性电子产业有较大意义。
