摘要 现代消费电子产品正在飞速发展,并向着轻量化、高集成化、柔性化发展。电子产品具有机械柔性成为电子学发展的一个重要趋势。然而,柔性电子对互连材料有严格的要求。除了提供电性能、信号传输等常规功能外,柔性电子器件的互连还需要在机械变形过程中保持良好的机械稳定性和电气互连。导电银浆作为柔性电子互联的关键材料受到广泛研究,如何得到高导电性、优异柔性的导电银浆是制备柔性电子产品必须解决的问题。基于此,本工作提出了用多官能度异氰酸酯与聚酯二元醇制备的聚氨酯作为有机载体来制备导电银浆,3D显微镜、电学性能和力学性能测试的结果表明,制得的导电银浆具有优异的印刷性能、导电性能和柔性。

Abstract: Modern consumer electronic products are developing rapidly, and towards the light weight, high integration, flexible development. Mechanical flexibility has become an important trend in the development of electronics. However, flexible electronics have strict requirements for interconnecting materials. In addition to providing conventional functions such as electrical performance and signal transmission, the interconnection of flexible electronics requires good mechanical stability and electrical interconnection during mechanical deformation. As the key material of flexible electronic interconnection, conductive silver paste has been widely studied. How to obtain the conductive silver paste with high conductivity and excellent flexibility is a problem that must be solved in the preparation of flexible electronic products. Based on this work, polyurethane prepared by multi-functional isocyanate and polyester diol was proposed as an organic carrier to prepare conductive silver paste. The results of 3D microscopy, electrical and mechanical properties test show that the prepared conductive silver paste has excellent printing properties, electrical properties and flexibility.
