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. Dopamine, 3,4-Dihydroxyphenylalanine(DOPA) which contain catechol moieties was selected as a starting material and synthesized monomer by reacting with methacryloyl chloride. The synthesized dopamine methylacrylamide (DMPA), N-(3,4-dihydroxyphenethyl) methacrylamide (NDPMA) were characterized through FT-IR, 1H NMR and 13C NMR. 3D printed and crosslinked dental crowns were fabricated by photopolymerization of ethoxylated bisphenol-A dimethacrylate (EBPDMA) with or without DMPA, NDPMA using DLP 3D printer, and used to evaluate their mechanical strengths and hardness. |
