Abstract
Described herein are durable coatings, i.e. for medical devices, and methods of forming the coatings.
Claims22
A coating, comprising a base coat and a top coat covalently linked to the base coat, wherein the base coat includes an alkylsilanyl moiety, and the top coat includes a polymeric moiety having an amine moiety, wherein the coating is about 100 nanometers thick or less.
A process for forming a coating, comprising a base coat and a top coat covalently linked to the base coat, wherein the base coat includes an alkylsilanyl moiety, and the top coat includes a polymeric moiety having an amine moiety,
- wherein the coating is 100 nanometers thick or less,
- wherein the process comprises contacting the alkylsilanyl moiety with the polymeric moiety having an amine moiety to form the coating, and
- wherein the alkylsilanyl moiety is a haloalkylsilanyl moiety.
A process for coating a medical device, including:
- a) contacting a halosilanyl compound with a surface of the medical device to form a base coat;
- and
- b) contacting the base coat with a hydrophilic polymeric moiety having an amine moiety to form a top coat,
- wherein the base coat is covalently linked to the surface of the medical device, and the top coat is covalently linked to the base coat, and
- wherein a combined thickness of the base coat and top coat is about 100 nanometers or less.
