Mussel-inspired catechol polymers attract attention with strong interfacial interactions via hydrogen bonding, enabling diverse applications, including the biomedical industry. 3,4-dihydroxyphenylalanine (DOPA) with catechol moieties was reacted with methacrylic anhydride to synthesize a polymerizable monomer. Dopamine methylacrylamide (DMA) was characterized using FT-IR, ¹H-NMR, and ¹³C-NMR spectroscopies. Subsequently, it was mixed with ethoxylated bis-GMA (EBPDMA) in various compositions to 3D print using the DLP (Digital Light Processing) technique. The synthesized DMA was copolymerized with MMA (methyl methacrylate) to be applied to bone cement. Additionally, it was copolymerized with acrylic acid and 2-HEMA (2-hydroxyethyl methacrylate) to formulate glass ionomer cement for dental restorative applications, and characterized through GPC, FT-IR, and ¹H-NMR spectroscopies. The specimens fabricated with various ratios were used to measure mechanical properties such as compressive strength and flexural strength.
