Polyphenol is a kind of aromatic alcoholic compound found in plants and fruits, and is characterized by having several hydroxyl groups as a functional group with multiple phenol units in a molecule. Since polyphenols have antimicrobial, antioxidant, and antiinflammatory activities, they have recently received great attentions as functional coating materials. However, interestingly, no all polyphenols can act as a coating precursor. Naringenin, which is generally extracted from citrus fruit, is an example as a poor coating precursor. To get more understanding on polyphenol chemistry, in this study, we have engineered naringenin-based nanocoating by using an amine cross-linker. All of the formed films were characterized by ellipsometry, contact angle goniometry, and X-ray photoelectron spectroscopy. The current approach can be applied to various substrates. We believe that our study can serve as a basis to understand polyphenol chemistry and to prepare functional polyphenolic coatings. |
