Abstract
The invention relates to a method for preparing a nano platinum-coated gold particles film composite material, which comprises the following steps: preparing a gold-molybdenum alloy film on surface of a polyimide matrix, keeping a certain temperature for the matrix so that gold atoms can be promoted to grow for obtaining the gold particles on the surface of the alloy film, and then depositing the platinum film on the surface of the prepared gold particles film to obtain the product. The method employs a magnetron sputtering double target co-deposition technique to prepare the gold-molybdenum alloy film and a matrix in-situ heating technology , the nanogold film/gold particles composite material can be prepared without a template, the nano platinum-coated gold particles film composite material with large comparison area and high performance is sputtered and deposited on the surface of the nanogold film/gold particles composite material, compared with a pure platinum film, the specific surface area of the nano platinum-coated gold particles film is increased by more than 20%.
