Abstract: With the rapid development of modern electronic technology, a large amount of e-waste puts huge pressure on the environment. The cellulose-based flexible conductive composite material has incomparable advantages with traditional petroleum-based conductive products, such as lightweight, degradable, renewable, bio-compatible, and so on. In recent years, paper-based flexible conductive materials have gradually become a research focus in this field. This article reviews the research progress of paper-based flexible conductive materials at home and abroad in recent years, describes the working principle of flexible conductive materials, summarizes the preparation methods and related applications of paper-based flexible conductive materials in detail, and the paper-based flexible conductive materials urgently need to be solved and the future development trend is summarized and prospected.
