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.
本公开的实施方案包括包含低聚多酚层的涂层。低聚多酚层可用作医疗设备上的中间涂层,与合成或天然聚合物氢键结合,而合成或天然聚合物又可用作面层或与另一涂层进一步结合。多层涂层可提供血液相容性或润滑性等特性。在其他实施方案中,低聚多酚层被用作医疗设备的止血层,可与血液接触并促进凝血。低聚多酚层还可用于医疗设备的内表面(如内径),以防止细菌附着。低聚多酚层还可用于体外诊断物品或细胞培养装置的表面,以促进生物分子的吸附。
