Embodiment Construction
[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following technical solutions in the present invention are clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0019] The nanoporous film capacitor electrode material provided by the invention is prepared by the following method:
[0020] The base material nanoporous gold (NPG) is prepared by placing a 100nm-thick gold-silver alloy film in concentrated nitric acid by a dealloying corrosion method, and freely corroding it for 20-60min at 20-50°C. NPG is used as the base material, and it is placed in the plating solution. The preparation of the plating solution: in the 1-3m...
