Abstract

A method of coating a metallic substrate includes immersing a metallic substrate in a polymer composition including a conductive 3,4-ethylene dioxythiophene (EDOT) polymer, a gelatin polyelectrolyte, an antibacterial drug, an organic solvent, and an inorganic salt solute, and further coating the polymer composition onto a surface of the metallic substrate by cyclic voltammetry to form a coating on the surface of the metallic substrate. The coating on the metallic substrate is performed such that the gelatin and the antibacterial drug are uniformly distributed throughout the coating, and the coating has a thickness between 7.0 and 15.0 micrometers. The metallic substrate is a stainless steel (SS). An implantable medical device including a metallic substrate coated by the present method.
