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。
Hydrothermal method was used to prepare sheet-shaped Co3O4 superhydrophobic surface on aluminum substrate. The structure and surface morphology of precursor and end product were investigated by X-ray diffraction and scanning electron microscopy. The effects of hydrothermal reaction time On the microstructure of Co3O4 surface morphology, microstructure evolution with the reaction time was analyzed in detail; combined with Cassi-Baxter composite model analysis of Co3O4 superhydrophobic surface lubrication performance; the use of intense pressure water column on the Co3O4 superhydrophobic surface impact Stability test. The results show that the super-hydrophobic sheetlike Co3O4 surface obtained at the reaction time of 10h has the best performance and has good water shock resistance.
