Abstract
In order to obtain adhesive biomaterials inspired by mussels, the intermediate derivatives of dopamine, N-methacryloyl 3,4-dihydroxyl-phenylamine (dopamine methacryla-mide DMA), was synthesized by grafting methacrylate anhydride to dopamine. The structure of the compound was confirmed by fourier transform infrared spectroscopy and nuclear magnetic resonance. The thermal stability of DMA was also characterized by thermo gravimetric analysis and differential scanning calorimeters techniques. The surface morphology of DMA crystal was analysed by scanning electron microscope analyses. The present result showed that the synthesis of new monomers was successfully fulfilled and the new compounds retain the hydroxyl functional groups. The surface morphologies and thermal stability of DMA crystal were also altered by grafting reaction.
