Abstract

Printed conductive polymer composites allow for the bespoke manufacture of products with complicated geometries, which is critical for rapid prototyping and adaptability of flexible electrical devices. However, it is still challenging to prepare environmentally friendly and sustainable conductive polymer composites with aqueous solvent systems which accomplish excellent printing and electromechanical properties at the same time. In this work, the effect of composite components on performance was explored, and orthogonal tests were utilized to discover the precise formulation of new green aqueous conductive polymer composites with superior performance. The printing accuracy of the conductive polymer composites was enhanced (printed circuit burrs less than 20 μm) and the dependability of the printed circuits as well as the failure mechanism during electrochemical migration (ECM) were thoroughly investigated. As a proof of concept, ultrahigh frequency (UHF) flexible linearly polarized antennae with read range forward surpassing 10 m was designed and printed.

用于柔性电子产品的具有良好印刷性和导电性的水性导电聚合物复合材料

印刷导电聚合物复合材料允许定制制造具有复杂几何形状的产品，这对于快速原型制作和柔性电气设备的适应性至关重要。然而，利用水性溶剂体系制备环保和可持续的导电聚合物复合材料，同时实现优异的印刷和机电性能，仍然是一个挑战。本研究探讨了复合材料组分对性能的影响，并采用正交试验的方法找到了性能优异的新型绿色水性导电聚合物复合材料的精确配方。提高了导电聚合物复合材料的印刷精度（印刷电路毛刺小于20 μm），深入研究了印刷电路的可靠性以及电化学迁移（ECM）过程中的失效机理。作为概念验证，设计并打印了读取范围超过10 m的超高频柔性线极化天线。

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
