Abstract

The invention relates to a nano porous metal/conducting polymer composite material and a preparation thereof, belonging to the technical field of conducting polymer composite materials. The nano porous metal/conducting polymer composite material is characterized by comprising nano porous metal and a conducting polymer layer with the thickness of 1 nm-100 Mum; and after the conducting polymer layer is deposited, the three-dimensional continuous pore wall surface of nano porous metal is evenly covered. The nano porous metal/conducting polymer composite material does not need an adhesive; conducting polymer is directly and electrically polymerized on the nano porous metal pore wall prepared by the dealloying method; high conductivity of nano porous metal, relatively high activity specific surface area, and performance of conducting polymer are integrated, thereby further improving the high conductivity and activity specific surface area of conducting polymer, and improving the use efficiencies of conducting polymer in aspects of chemical catalysis and preparation sensors, storers, super capacitors and the like.

Description

technical field [0001] The invention relates to a nanoporous metal / conductive polymer composite material and its preparation, belonging to the technical field of conductive polymer composite materials. Background technique [0002] Porous metal materials have always been the focus of attention, and nanoporous metals prepared by dealloying have received widespread attention. For example, Karl Sieradzki, Roger C.Newman et al. reported a method for electrochemically corroding gold-silver alloys to prepare porous gold in 1990. (Karl Sieradzki, Roger C. Newman "Micro-and Nano-porous Metallic Structures" US Patent, 4,977,038, Dec. 11, 1990). The pore size and pore wall thickness of the porous metal materials prepared by the dealloying method are all below 1000 nanometers. The nano-metal materials prepared by this method not only have an open porous structure and high electrical conductivity, but also have a clean and highly active surface. It can provide superior conditions for l...
