  • Method for Preparing Chitosan/Heparinized Graphene Oxide Composite Multilayer Film on Surface of Medical Magnesium Alloy
    Publication number: 20200254151
    Abstract: A method for preparing a chitosan/heparinized graphene oxide composite multilayer film on the surface of a medical magnesium alloy comprises the following steps: firstly preparing negatively charged heparinized graphene oxide; then performing surface chemical treatment and self-assembly of 16-phosphonohexadecanoic acid molecules on the medical magnesium alloy; further covalently immobilizing chitosan on the surface of the magnesium alloy, thereby constructing a positively charged material surface; finally, alternately immersing the surface-modified magnesium alloy material in heparinized graphene oxide and a chitosan solution, and then fully adsorbing, and obtaining the chitosan/heparinized graphene oxide composite multilayer film after drying.
