Popis: Abstract Coloring and identification procedures for medical devices are important to reduce the risks of defective medical devices or incorrect operations and implantations. The study herein reports a novel platform of color pigment‐modified Parylene coatings to fulfill the needs of medical coatings, providing a surface modification route to alter the important property of color for an underlying material and/or device from its original color. Modification with a naphthalimide derivative is employed for the Parylene precursor. The synthesis of the final color Parylene coating is performed based on a vapor‐phase deposition polymerization process, and the coating is conformally coated on a variety of materials regardless of the shape or dimension. Furthermore, control of the color to create a series of color‐changing Parylene coatings is enabled by vapor deposition copolymerization with a second Parylene derivative source, and predictable color tuning from a primary to a secondary and/or tertiary color is achievable in the experiments and shows accordance with color theory. The reported coating platform represents a colored coating tool and is biocompatible for biotechnological applications.
