Coated structured substrates and methods of making same

Abstract

The present disclosure provides a coated structured article. The article includes a substrate with a structured major surface including features, in which the structured major surface includes protruding features and/or recessed features. The article also includes a coating disposed on at least a portion of the features, the coating including a first material and a second material. The first material has a first binding group and the second material has a second binding group, and the first binding group and the second binding group have complementary interactions. A method of making the article is also provided. The method includes depositing layers using layer-by-layer self-assembly to form a coating on a structured substrate.
