제목 Block Copolymer/Tannic Acid Hydrogel
초록 Physical hydrogels consisting tannic acid (TA) and water soluble-polymers such as polyethylene oxide (PEO) have been utilized for drug delivery and hemostatic applications due to their biocompatibility and adhesive properties. The transient supramolecular network held by hydrogen bonding provides modulus to resist external. However, the resulting materials typically behave as viscoelastic liquid with low elastic moduli. Here, we present the preparation of hydrogel via TA-mediated aggregation of amphiphilic and biocompatible block polymer micelles in aqueous solution. Bridging of the micelles the hydrogen bonding between TA and the corona segment renders enhanced mechanical and adhesive properties. We will discuss the structure-property relationship of block polymer/TA hydrogels.
