Abstract

The stretchable conductive ink is a functional material which enables the ink film to have better electrical conductivity after stretching and folding. It has broad application prospects in the field of flexible electronic devices. From the perspective of realizing the stretchability and electrical properties of ink films, this paper introduces the most research progress of nanometal-based stretchable conductive inks. The definition and characteristics of flexible electronics are introduced, and several methods for flexible electronic devices are mainly summarized. The mechanism and realization of stretchable conductive inks are reviewed. Then the applications of stretchable conductive inks based on these methods are introduced. Finally, the problems and technical shortcomings of the stretchable conductive ink in the development of flexible electronic devices are analyzed and the prospect of this new functional ink is predicted. The application of this ink can simplify and optimize the production process of stretchable conductor and make important impacts to flexible electronics.
