Analysis of synergistic adhesion properties and nanomechanical interactions of catechol and amine functionalized polyether with various compositions |
| 초록 |
Mussels’ extraordinarily strong underwater adhesion has attracted interests in various fields, and recently, continuous researches on the adhesive mfps have led to a conclusion that Dopa (3,4-dyhydroxyphenyl alanine) and cationic lysine are the two main components responsible for wet adhesion. However, the synergistic effects of catechol and amine groups are rarely investigated in copolyether based polymeric systems. In this study, the amine-catechol functionalized random copolymer was prepared with precisely controlled functional group composition, and Surface force apparatus (SFA) measurement was performed to investigate the synergistic interaction. As a result, the interaction energy was the highest in the ratio of catechol 1: amine 3 and stronger at pH 7 compared to pH 3. This study shows a quantified database of synergistic effects of amine-catechol in polymer systems and is expected to provide important information for future studies on underwater adhesion. |
