我们报道了一种通过在多巴胺的水溶液中简单地浸涂物体来形成多功能聚合物涂层的方法。受贻贝中粘附蛋白质组成的启发，我们使用多巴胺自聚合在各种无机和有机材料上形成薄的表面粘附聚多巴胺膜，包括贵金属，氧化物，聚合物，半导体和陶瓷。二次反应可用于产生各种ad层，包括通过沉积长链分子结构单元的自组装单层，通过无电金属化的金属膜，以及通过接枝大分子的生物惰性和生物活性表面。
We report a method to form multifunctional polymer coatings through simple dip-coating of objects in an aqueous solution of dopamine. Inspired by the composition of adhesive proteins in mussels, we used dopamine self-polymerization to form thin, surface-adherent polydopamine films onto a wide range of inorganic and organic materials, including noble metals, oxides, polymers, semiconductors, and ceramics. Secondary reactions can be used to create a variety of ad-layers, including self-assembled monolayers through deposition of long-chain molecular building blocks, metal films by electroless metallization, and bioinert and bioactive surfaces via grafting of macromolecules.
