| 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. |
