Development of Bio-inspired Monomer, Dopamine Acrylamide

In quartz crystal microbalance (QCM) analysis, dopamine acrylamide (DopAm) accumulated on the surface of SiO2, ITO, and Ag over time. These results suggest that the scaffolds on these surfaces are formed with the catechol groups and DopAm accumulates by the intermolecular hydrogen bondings. And in the investigation of the surface adhesion and the tackiness, by adding only 1% of DopAm to UV curing monomers, DopAm was effective to several materials and several pairs of dissimilar materials. Considering the behavior of the QCM, these results suggest that DopAm has the effect of resin reinforcement by intermolecular hydrogen bondings with the functional groups of other monomers as well as scaffolding by catechol groups. To further applications, a redox characterization of DopAm was investigated by a cyclic voltammogram (CV).
