研究目的
Investigating the controlled fabrication of Ag nanostructures on a porous template on nitinol to improve antibacterial properties.
研究成果
The study successfully demonstrated the controlled fabrication of Ag nanostructures on nitinol templates using electrodeposition, with collagen concentration significantly affecting the shape and distribution of Ag crystals. Optimal collagen concentrations resulted in well-dispersed spherical Ag nanostructures, offering potential for improved antibacterial properties in biomedical applications.
研究不足
The study is limited by the specific conditions of electrodeposition and the concentrations of collagen used, which may not cover all possible variations in Ag nanostructure formation. The environmental impact of the chemicals used was not assessed.
1：Experimental Design and Method Selection:
Plasma electrolytic oxidation was used to produce oxide film on nitinol surfaces. Electrodeposition in an AgC2H3O2-based solution with varying collagen concentrations was employed to fabricate Ag nanostructures.
2：Sample Selection and Data Sources:
Nitinol plates were used as substrates. AgC2H3O2 and collagen solutions were prepared as electrolytes.
3：List of Experimental Equipment and Materials:
Direct current power supply, potentiostat with three electrodes, scanning electron microscopy (SEM), electron probe micro analysis (EPMA), X-ray diffractometer (XRD).
4：Experimental Procedures and Operational Workflow:
Oxide film formation on nitinol, electrodeposition of Ag nanostructures under controlled conditions, characterization of morphology and composition.
5：Data Analysis Methods:
SEM for morphology observation, EPMA for elemental distribution, XRD for composition identification.
