“…As shown in Figure f,g, both the S/Tannin-dyed fabric and S/Tannin/HA/FA/Fe fabric displayed excellent antibacterial properties: the test bacteria Escherichia coli and Staphylococcus aureus inoculated on the surface of the fabrics showed a high level of death and exhibited inhibition rates exceeding 99.9%. In general, the antibacterial mechanism of phenolic substances (including tannin, HA, and FA) was related to their strong protein-binding capacity and the resultant inactivation of the cellular proteins of microbes. , According to reports, tannins, HA, and FA not only exhibit independent antibacterial effects but also have synergistic antibacterial activity. , Therefore, the silk fabric prepared by tannin dyeing followed by HA/FA/Fe coating is a promising antibacterial fabric.…”

The facile fabrication of an eco-friendly multifunctional [flame retardant, antibacterial, and ultraviolet (UV) blocking performance] and double-sided heterochromatic silk fabric was developed. In this study, silk fabric was subjected to a dyeing process using plant tannins, followed by a one-sided coating with a colloidal suspension consisting of humic acid (HA), fulic acid (FA), and green alum, and finally underwent a 15 min steaming treatment. The results revealed that the Tannin/HA/FA/Fe system had a distinctive micromorphology toward the silk fabric, characterized by a finely layered, cracked brick-like coating on the silk yarns. The prepared fabric showed a limiting oxygen index (LOI) value of 28.5%, a UV protection factor (UPF) value of 53.1, and a bacterial inhibition rate of 99.99% against Escherichia coli and Staphylococcus aureus, meeting the criteria for high-grade refractory textiles, UV-protection textiles, and antibacterial textiles. Additionally, the multifunctions and color of the fabric exhibited substantial durability to repeated home washing. The coating process did not inhibit the thermal/moisture comfortabilities and handle of the silk fabric. Promisingly, the raw materials employed in the fabrication of the prepared fabric were entirely natural or derived from nature, emphasizing the eco-friendly nature of the process.

Polyphenol hydrogels have found widespread application in wound healing, bone repair, drug delivery, and biosensors due to their robust wet adhesion, high ductility, and excellent self‐healing ability. However, these hydrogels often exhibit low intrinsic cohesion, which limits their overall adhesive strength. Enhancing cohesion is critical for improving both the adhesion and mechanical properties of the hydrogels, thereby expanding their utility in biomedical fields. This review begins by exploring strategies to enhance the cohesion of polyphenol hydrogel adhesives, detailing modifications that act individually or synergistically. The importance of temporally regulating cohesion is emphasized to accommodate various applications and environmental conditions. Finally, this paper discusses remaining challenges in cohesion regulation and outlines prospects for future research. It is hoped that this comprehensive review will provide new insights into the development of advanced polyphenolic hydrogel adhesives and contribute to the design of “smart adhesives” for increasingly complex needs in biomedical applications.
