摘要
为了提高低温固化银系导电油墨的导电性,对导电机理进行了研究。通过实验研究了聚合物分子结构,银粉的含量、形貌、粒径,溶剂种类对导电性能的影响。得出:氯化聚乙酸乙烯为主体树脂,以片状与球状混合银粉(质量比为9:1)为导电填料,并以酮和酯组成混合溶剂,调制的导电油墨导电性最好,其Rs达9 mΩ/□。
In order to increase conductivity of silver ink, the conductive mechanism was studied. Effects of the polymer molecular structure, the silver powder content, morphologies, particle size and solvent kinds on conductivity were studies. The results show that using the chlorinating polyvinyl acetate as the corpus resin, mixture of flaky silever powder and spherical silever powder ζ= 9：1 as filler, with the compound solvent, can produce a best electric conductive silver ink, Rs is 9mΩ/□.
