摘要:

纳米材料功能化的新型织物因具有抗污、防水等特性,得到了广泛应用,但背后的原理却少有了解。本实验通过铜还原反应,在织物表面生成纳米铜涂层,得到超疏水织物;通过氧化处理,使织物展现出水下超疏油、油下超疏水性。通过展示铜超浸润织物的特性,并结合多种互动方案探究背后的原理,具有重要的科普意义和价值。

Abstract:

Nanomaterial coatings endow traditional fabrics with incomparable properties, such as anti-fouling and waterproofing, and have thus garnered widespread attention. However, the underlying principle of such properties is not widely known. In this experiment, a superhydrophobic fabric coating was produced by a simple copper reduction reaction. After oxidation treatment, the fabric exhibited superhydrophobicity in oil and superoleophobicity in water. Thus, demonstrating the characteristics of copper superwetting fabrics with typical interactive experiments would be significant in popularizing science.
