| titleOfInvention | Method for preparing organic film on surface of NiTi alloy |
| abstract | The invention relates to an organic film-based NiTi alloy surface modification method, and belongs to the field of metal material surface modification. The method comprises the following steps of: irradiating a preprocessed NiTi alloy by using 60Co at room temperature, immersing in a mixed solution of H2O2 and H2SO4 for activation, performing silanization by using vinylsilane, irradiating by using gamma-rays of the 60Co, and grafting organic monomer or polymer to obtain the organic film on the surface of the NiTi alloy. The organic film prepared on the surface of the NiTi alloy can be prepared into a biological material with high biocompatibility through a molecular design; the film is bound with the surface of the NiTi alloy in a form of covalent bond, and the binding force is large; the grafting ratio of the reaction is controlled by adjusting parameters such as irradiation dose, dose rate, organic monomer or polymer concentration and the like, and the performance of the organic film on the surface of the NiTi alloy is improved; the adopted mutual irradiation grafting method is easy and convenient to implement, the utilization rate of radiation energy is high, a chemical initiator is not needed to be added, and the product is pure; meanwhile, materials can be sterilized in the irradiation process, and biomedical materials are convenient to use. |
