Surface Modification of WE43 Magnesium Alloys with Dopamine Hydrochloride Modified GelMA Coatings

As biodegradable medical implants, magnesium alloys have attracted great concerns due to their desirable biological and mechanical performances. Nevertheless, the overfast degradation rate of makes it difficult make full use potential in sciences. Therefore, is a hot issue control functionalize via surface modifications. Herein, methacrylate gelatin (GelMA) hydrogel was adopted as coatings on WE43 behaviors alloys. Inspired by mussels, dopamine (DOPA) hydrochloride modify GelMA further coatings. The compositions, swelling properties, behaviors, morphologies samples were characterized UV-Vis spectrophotometer, nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), immersion test. It shown that GelMA-DOPA composites could be obtained controlled adjusting compositions DOPA. Furthermore, can tightly bonded Mg
