摘要
采用水热法在铝片基底表面成功制备了片状花簇Co3O4超疏水表面,利用X射线衍射和扫描电镜研究了前驱体及终端产物的成分结构和表面微观形貌;探讨了水热反应时间对Co3O4表面微观形貌结构的影响,详细分析了微观结构随反应时间的演变过程;结合Cassi-Baxter复合模型分析了Co3O4超疏水表面的润滑性能;利用强压水柱对Co3O4超疏水表面进行了抗冲击稳定性试验。结果表明,反应时间为10h时得到的片状花簇Co3O4超疏水表面的性能最佳,并具有良好的抗水冲击性能。
Flaky-cluster Co3O4super-hydrophobic surface was successfully prepared on on aluminum substrate via hydrothermal method.The phase composition and surface morphology of the precursor and terminal product were detected by X-ray diffraction and scanning electron microscopy.The effect of reaction time on Co3O4 surface morphology was investigated,and microstructure evolution with reaction time was analyzed in details.The lubrication performance of Co3O4super-hydrophobic surfaces were analyzed with Cassie-Baxter composite model.Finally,the impact resistant stability of Co3O4super-hydrophobic surface was tested with high pressure water column.The results show that flaky-cluster Co3O4super-hydrophobic surface prepared by 10 hreaction has the best super-hydrophobic performance and good water impact resistant stability.
