• Highlights

• A polysiloxane and LbL composite coating was prepared on AZ31 alloy.

• The drug release from the composite coating lasts for 17 days.

• The composite coating shows corrosion resistance and antibacterial effect.

• It is a versatile approach to develop functional coatings on magnesium implants.

• Abstract

An investigation on the corrosion resistance and antibacterial properties of polyelectrolytes and polysiloxane coatings on magnesium alloy with gentamicin was made. The microstructure and composition of the multilayer coatings were characterized by using Fourier transform infrared spectroscopy, X-ray diffractometer and scanning electron microscopy. The analysis of electrochemical measurement in HBSS suggested that the composite coatingsimproved the corrosion resistance of AZ31 alloy. Finally, the result ofplate-counting method demonstrates the effective antibacterial properties of the functionalized substrates. Thus, it can be concluded that the multilayer-treatment reported here is a versatile approach to develop antibacterial and anticorrosion coatings on magnesium implants.
