Versatile Multifunctional Coatings
In article number 2206943, Lingyun Jia and co‐workers develop a one‐step assembly strategy to construct host‐guest polyphenol coatings using tannic acid and polycyclodextrin particles. These coatings are responsive to high‐temperature steam and pH, and can form free‐standing films under physiological conditions. Furthermore, various metal ions and functional particles can incorporate into the coatings to enhance their versatile properties for multiple application prospects.
