The invention discloses a continuous flexible conductive material preparation device and method.The device comprises a continuous flexible material, a guide roller and a conductive coating assembly, the assembly is sequentially provided with a tackifying unit, a powdering unit, a curing unit, a chemical plating unit and a post-processing unit in the material conveying direction, the center lines of conveying channels of all the units are collinear, and the interface gap is smaller than or equal to 2 mm. The micro-nano metal powder seed source is planted through the powdering device, rapid growth and closing of the micro-nano metal powder seed source are achieved through chemical plating after solidification, a compact conductive network is constructed, and a finished product is obtained.The short-process, rapid, efficient and environment-friendly preparation of the continuous flexible high-conductivity material can be achieved, the prepared material is low in cost, good in conductivity and high in durability, material transmission deviation is avoided, and the continuous flexible high-conductivity material can be obtained. The method improves the compactness of the coating and the consistency of products, recovers redundant adhesion liquid and catalyst particles, reduces the production cost, and is suitable for preparation of continuous flexible conductive materials such as conductive yarns, fabrics and films.
