    Abstract: Embodiments of the disclosure include coatings comprising an oligomerized polyphenol layer. The oligomerized polyphenol layer can be used as an intermediate coated layer on a medical device that hydrogen bonds to a synthetic or natural polymer, which in turn can be used as a top coat or further associated with another coated layer. The multilayered coatings can provide properties such as hemocompatibility or lubricity. In other embodiments, the oligomerized polyphenol layer is used on a medical device as a hemostatic layer configured to contact blood and promote coagulation. The oligomerized polyphenol layer can also be used on the inner surface (e.g., inner diameter) of a medical device to prevent bacterial adherence. The oligomerized polyphenol layer can also be used on the surface of a in vitro diagnostic article, or a cell culture device to, promote adsorption of a biological molecule.

    Abstract: Embodiments herein include coated medical devices and coatings with salt groups. In an embodiment, a coated medical device is included, the coated medical device including a substrate and a polymeric layer disposed over the substrate. The polymeric layer includes a polymer and has an exterior surface. The coated medical device further includes a plurality of salt groups bonded to the polymer of the polymeric layer and disposed on the exterior surface of the polymeric layer. The salt groups can be the reaction product of a reactive group with an acid or base. In an embodiment, a method of making a medical device is included. Other embodiments are also included herein.
