  • Publication number: 20240173462
    Abstract: A method for preparing a poly(thioctic acid)-copper coating (poly(TA-Cu)) on a surface of a cardiovascular stent material includes: grinding a cardiovascular stent material with sandpaper until the surface of the cardiovascular stent material is flat and smooth, rinsing the cardiovascular stent material with deionized water and anhydrous ethanol in sequence, and drying the cardiovascular stent material to obtain a pre-treated cardiovascular stent material; dissolving thioctic acid in an alcoholic solvent, adding anhydrous copper chloride to a mixed solution of thioctic acid and the alcoholic solvent, stirring the mixed solution, to yield a precursor solution; treating the pre-treated cardiovascular stent material with the precursor solution, and drying, thus forming a poly(thioctic acid)-copper coating on the surface of the pre-treated cardiovascular stent material. The concentration of thioctic acid in the alcoholic solvent is 0.1-0.
