| 제목 | Effect of complex coacervate of mussel inspired copolymers |
| 초록 | Complex coacervation-phase separation occurs between positively and negatively charged in aqueous solutions. It is known that marine mussel has been consist of positively charged, however it can be induced the complex coacervate by strong cation-π interaction. Cation- π interaction was occurred between electron rich π system such as aromatic ring and cations, which it was a non-covalent interaction. In this work, marine mussel inspired, biomimetic water-borne adhesive was synthesized by radical copolymerization with different kinds of acrylate functional group. To better understand the complex coacervate, we investigated the effect of cation-π interaction by various kind of metal cations (Mg2+, Ca2+, Fe3+, V5+) and catechol of DOPA derivatives with different substrates. We found that catechol chelates metal ions to form strong complex coacervate with metal ions, including Mg2+, Ca2+, Fe3+ and V5+. |
