Molecular diversity in phenolic and polyphenolic precursors of tannin-inspired nanocoatings

The strong interfacial properties of selected plant polyphenols were recently exploited in forming functionally versatile nanocoatings via dip-coating. Here, we screened a library of similar to 20 natural and synthetic phenols and polyphenols, identifying eight catechol-, gallol- and resorcinolrich precursors capable of forming coatings. Several newly identified compounds expand the molecular diversity of tannin-inspired coatings.
