| 摘 要： | 目的研究表面结构与化学成分对结霜性能的影响。方法以具有不同结构参数的多孔阳极氧化铝表面为模板,以高密度聚乙烯为压印热塑材料,采用模板热压法在常压下制备柱状微结构表面。分析表面形貌,测试接触角,通过结霜实验研究其结霜性能。结果柱状微结构表面经化学修饰后,获得超疏水效果。结霜过程实验显示,制备的超疏水表面初始结霜时间更晚,结霜速率更慢。结论通过改变表面结构与表面化学成分均能对表面结霜性能产生直接影响,修饰后的柱状结构表面具有较好的抑霜效果。

| Abstract: | Objective To study the effects of surface structure and chemical composition on frosting parameters. Methods Surfaces with cylindrical microstructure were prepared by hot pressing method under atmospheric conditions using anodic aluminum oxide as the template and high density polyethylene as the thermoplastic material. The surface morphology was analyzed and the contact angle was investigated. The frosting performance was studied through the frosting experiments. Results Super-hydrophobic surfaces were obtained by surface modification using FAS. Experimental results of frosting process showed that the as-prepared superhydrophobic surface could delay the initial frosting time and reduce the growth rate of frosting process. Conclusion Both the surface microstructure and chemical composition had great influence on the frosting performance. The surface with cylindrical microstructure after modification using FAS had better frosting suppression capacity. |
