摘要
Abstract
The surface inertness of titanium alloy(TC4)presents limitations in terms of biocompatibility when used as a bone implant material.A hydrothermal growth method is employed to successfully construct a ZnO nanorod array coating on TC4 surfaces,exhibiting piezoelectric and photocatalytic properties.In biomineralization experiments conducted in simulated body fluid,effects of combined piezo-photocatalysis on the deposition of calcium phosphate(CaP)are investigated by applying vibration and ultraviolet(UV)light irradiation to the sample surfaces.A novel method for biomimetic deposition of CaP is proposed.The results show that the combined piezo-photocatalytic action of zinc oxide significantly enhances the deposition amount of CaP,outperforming the deposition achieved by either piezoelectric or photocatalytic action alone.Additionally,both isolated vibration and UV illumination demonstrate higher CaP deposition amounts compared with untreated samples.This research has prepared ZnO nanorod arrays on titanium alloy sheets and proposes a method utilizing the combined piezoelectric-photocatalytic effect to enhance CaP deposition,offering a new perspective for the further development and application of coating technologies and biomedical materials.关键词
