Supramolecular Adhesive Gel based on Tannic Acid and Biocompatible Water-Soluble Polymers via Hydrogen Bonding Complexation |
| 초록 |
Tannic acid (TA) is a naturally derived polyphenolic compound and possesses diverse bonding abilities. TA is capable of complexing or cross-linking macromolecules through multi-valent interactions such as hydrogen bonding, ionic and hydrophobic interactions. It also can coordinate with metal ions to form TA-metal networks. Therefore, TA is an ideal gelation binder in hydrogel formation. Herein, we report a simple and rapid gelation of naturally occurring and inexpensive TA with high molecular weight poly(N-vinyl pyrrolidone) and poly(2-ethyl-2-oxazoline) in aqueous solution. The characterization of these supramolecular hydrogels and their strong adhesive properties on different substrates will be presented. TA is already an FDA-approved compound, so studies of the TA-polymer conjugates are very promising for the future development of new biocompatible and adhesive gels for various biomedical applications. |
