Abstract

The invention relates to a porous metal foil as well as a preparation method and an application thereof. The method comprises the following steps of introducing a metal foil into an electroplating solution, and electrifying to form an electroplating layer on the surface of the metal foil; placing the metal foil loaded with the electroplating layer in a vacuum furnace, and sequentially carrying outtwo-stage heating treatment on the metal foil loaded with the electroplating layer under the condition of vacuum to obtain the porous metal foil. The pore size structure of the prepared porous metalfoil is controllable. The preparation method is simple, feasible, low in cost and small in pollution. The pore size distribution of the porous metal foil can be adjusted conveniently. The obtained metal foil has a thickness of 5 to 200 [mu]m and an average pore size of 100 nm to 10 [mu]m.

Description

technical field [0001] The invention belongs to the technical field of porous metal material preparation, and in particular relates to a porous metal foil and its preparation method and application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Porous metal materials have high strength, low density, low modulus, high temperature oxidation resistance, carbonization resistance and corrosion resistance, and have high specific surface area, continuously adjustable pore size, regular and orderly channel structure, etc. advantage. Therefore, it is widely used in filtration, heat insulation, noise reduction, catalysis and other processes in environmental protection, medicine,...
