| 摘 要： | 采用测量接触角和观测偏光显微镜对超疏水表面在冷凝条件下的疏水特性进行了研究, 发现冷凝蒸汽进入超疏水表面的微凸起内冷凝, 表面的疏水特性被破坏, 表面的润湿特性变得不均匀, 部分区域甚至呈现亲水状态. 根据实验结果提出了冷凝条件下粗糙表面表观接触角的计算模型, 并使用冷凝条件下表面接触角的测量结果进行了验证.

| Abstract: | The wettability of superhydrophobic surface has become the hot point in many fields.The wettability of the superhydrophobic surface under condensation state condition is studied by measurement of the contact angle and observation of polarizing light microscopy.It is found that the water vapor could condense in the small gap of the rough surface and the superhydrophobicity of the rough surface is destroyed.And the wettability of the superhydrophobic surface showed the heterogeneity,even some part became hydrophilic.According to the analysis,a calculation model is proposed for the condensing droplets on superhydrophobic surface and it was validated by the measurements of contact angle. |
