In order to develop the next generation of biomedical polymer, many reseraches have been focused on bio-inspired technologies. Catechol group, one of the most notable materials found in mussel foot protein, has strong adhesive properties due to its better interaction with substrates through hydrogen bond, metal-ligand complexes and pi-pi stacking, leading to improved mechanical properties to commercial dental resin. 3,4-Dihydroxyphenethylamine (dopamine) which contains catechol moieties was selected as a starting material and used to synthesize 3D printable and light curable monomer by reacting with methacryloyl chloride. The synthesized dopamine methylacrylamide (DMPA) was characterized through FT-IR, NMR, XPS. 3D printed and crosslinked dental crowns were fabricated by photopolymerization of urethane dimethacrylate (UDMA), ethoxylated bisphenol-A dimethacrylate (EBPDMA) with or without DMPA using DLP 3D printer, and used to evaluate their flexural strength and hardness.
