NOVELTY - Preparing superhydrophobic anti-kill integrated functional surface with shape memory function, comprises mixing polylactic acid particles with 20-80 ml organic solvent, stirring at room temperature to obtain polylactic acid matrix solution, adding 10-50 mg graphene into 5-40 ml organic solvent, and ultrasonically dispersing to obtain a graphene dispersion, mixing the polylactic acid matrix solution with the graphene dispersion, and stirring uniformly, curing to obtain polylactic acid-graphene sample film, taking 50-100 mg of hydrophobic silicon dioxide, adding into 10-50 ml alcohol solution, stirring at room temperature to obtain silicon dioxide dispersion, fully mixing with 1-10 ml 1-5 wt.% alcoholic solution of binder, and ultrasonically treating to obtain silicon dioxide/binder mixed solution, coating the silicon dioxide/binder mixture on the surface of the polylactic acid-graphene sample film, and drying at room temperature. USE - The method is useful for preparing superhydrophobic anti-kill integrated functional surface with shape memory function. ADVANTAGE - The polylactic acid-graphene/silicon dioxide super-hydrophobic anti-killing integrated functional surface can effectively inhibit the Escherichia coliand Staphylococcus aureuson the material surface field planting the antibacterial adhesion rate is more than 99.0% and under the action of the near-infrared light, the generated local high temperature not only can trigger shape memory effect, but also can realize the fast inactivation of the bacteria. The raw material of the invention is low in cost, simple in preparation method, capable of mass production, and has good application prospect in the field of implantable medical appliance. A certain thermal stimulation can be returned to the initial shape, using characteristics, which can reduce the damage of the stent in the use process of the lesion, and increase the push performance of the stent system. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a superhydrophobic anti-kill integrated functional surface with shape memory function.
