Flexible electronics products have attracted wide attention because of their excellent flexibility, conductivity and stability. In this study, the liquid phase reduction method was used to in situ reduce fractal-structured silver particles (FSSPs) on cellulose surface to prepare conductive paper with excellent conductivity, and good stability and flexibility. The experimental results show that when the mass ratio of silver to cellulose was 1.5:1, the sheet resistance of conductive paper is as low as 0.02 Ω·sq, and the conductivity reaches 1041.33 S cm, which shows excellent conductivity. In order to expand the application of conductive paper in the field of flexible wearable electronic products, the mechanical stability and oxidation resistance of conductive paper were tested. The results show that the conductive paper has good stability and is expected to replace the flexible electronics products made of plastic.
柔性电子产品因其优异的柔韧性、导电性和稳定性而受到广泛关注。在这项研究中，采用液相还原法在纤维素表面原位还原分形结构的银颗粒（FSSPs），制备出具有优异导电性、良好稳定性和柔韧性的导电纸。实验结果表明，当银与纤维素的质量比为 1.5:1 时，导电纸的方阻低至 0.02 Ω·sq，电导率达到 1041.33 S cm，表现出优异的导电性。为了拓展导电纸在柔性可穿戴电子产品领域的应用，对导电纸的机械稳定性和抗氧化性进行了测试。结果表明，导电纸具有良好的稳定性，有望替代由塑料制成的柔性电子产品。
