23 Jul Preparation method of dysprosium-molybdenum-nickel alloy/polymethyl methacrylate scaffold material
Abstract
The invention belongs to the technical field of biomedical materials, and relates to a preparation method of a dysprosium-molybdenum-nickel alloy/polymethyl methacrylate scaffold material. The preparation method of the scaffold material comprises the steps of cleaning a polymethyl methacrylate scaffold material, carrying out surface modification on the scaffold material, carrying out catalytic activation, and chemically plating dysprosium-molybdenum-nickel alloy. The preparation method has the advantages that the organic carbon overflow rate of the scaffold material is reduced by 99% or more, and Mohs hardness reaches up to 6.5; after a human body fluid corrosion simulation test is carried out on the scaffold material for 180 days, the metal ion overflow rate is less than 1ppm, namely, the scaffold material has very high biological environment reliability. The dysprosium-molybdenum-nickel alloy/polymethyl methacrylate scaffold material can be used for tissue engineering scaffold materials, and has bright and clear application prospect and huge market potential.
