  • Patent number: 10292276
    Abstract: The inventive concepts relate to a method of manufacturing a hybrid metal pattern and a hybrid metal pattern manufactured thereby. In the method, the hybrid metal pattern may be manufactured on a substrate (e.g., a flexible substrate), formed of various materials, at room temperature without damaging the substrate, by a wire explosion method in liquid and light-sintering. In more detail, when performing the wire explosion method in liquid according to conditions of the inventive concepts, metal particles having uniform nano-sizes and uniform micro-sizes can be formed by a simple process, and additional dispersing and collecting processes can be omitted. In addition, conductive hybrid ink is formed by adding a metal precursor and then is light-sintered. In this case, the hybrid metal pattern can be manufactured by a very simple process.
