研究目的
To develop a simple and cost-effective method for fabricating stable superhydrophilic aluminum surfaces using nanosecond laser and ethanol solution post-treatment, and to understand the mechanism behind the superhydrophilic behavior.
研究成果
The method presented allows for the rapid fabrication of stable superhydrophilic aluminum surfaces with good hydrophilic persistence, suitable for industrial applications such as anti-atomization, medical devices, and sensors.
研究不足
The study does not explore the long-term stability beyond 40 days or the effects of varying environmental conditions on the superhydrophilic properties.
1：Experimental Design and Method Selection:
The study used nanosecond laser ablation to create micro-nanostructures on aluminum surfaces, followed by post-treatment in boiled 45% ethanol solution.
2：Sample Selection and Data Sources:
High-purity aluminum sheets were used as the experimental material.
3：List of Experimental Equipment and Materials:
Nanosecond laser (HANS laser EP-20-SHG), field emission electron microscope (FEI Apreo), contact angle measurement instrument (Nakatomi JC2000DM), infrared spectrometer (Nicolet IS10).
4：0). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Aluminum sheets were laser-ablated, then soaked in boiled ethanol solution, and their wettability and stability were tested over time.
5：Data Analysis Methods:
Contact angle measurements and FT-IR spectroscopy were used to analyze the surface properties and chemical composition.
