Catechol-containing polymers, which have excellent adhesion function derived from mussels, have recently attracted much attention. Strong interaction between interfaces due to the catechol group with the hydrogen bond allows to apply to various field. Dopamine, 3,4-dihydroxyphenylalanine (DOPA) with catechol moieties, were selected as a starting material to synthesize polymerizable monomer by reacting with methacrylic anhydride. The synthesized dopamine methylacrylamide (DMA) was characterized through FT-IR, 1H-NMR and 13C-NMR spectroscopies and mixed with ethoxylated bis-GMA (EBPDMA) with various compositions to 3D print by DLP technique. Catechol-functionalized polymers are synthesized by free radical polymerization of dopamine methacrylamide (DMA) and methyl methacrylate (MMA) in DMF. The polymer with the crosslinked structure was characterized through GPC, FT-IR and 1H-NMR spectroscopies. The mechanical properties of fabricated specimens such as compressive and flexural strengths were evaluated by UTM.
