摘要 基于土壤生物体表的脱附特性和以荷叶为代表的生物体表的自清洁特性,通过化学涂镀的方法在金属纤维表面制备Ni-P合金镀层,对仿生金属纤维自清洁过滤材料进行了研究。应用X射线衍射仪(XRD)研究了镀层的晶体结构和晶粒尺寸,应用扫描电子显微镜(SEM)和透射电子显微镜(TEM)观察了镀层的表面结构和表面形貌特征,应用光学接触角测量仪(OCAM)测量了金属丝网表面的水接触角(WCA),并对纤维材料过滤效率和压降进行了讨论。实验结果表明,经过表面处理后的仿生金属丝网过滤材料表面润湿特性得到了明显的改善,压降没有大幅度的增加,过滤效率得到了一定程度的提高。 基于土壤生物体表的脱附特性和以荷叶为代表的生物体表的自清洁特性,通过化学涂镀的方法在金属纤维表面制备Ni-P合金镀层,对仿生金属纤维自清洁过滤材料进行了研究。应用X射线衍射仪(XRD)研究了镀层的晶体结构和晶粒尺寸,应用扫描电子显微镜(SEM)和透射电子显微镜(TEM)观察了镀层的表面结构和表面形貌特征,应用光学接触角测量仪(OCAM)测量了金属丝网表面的水接触角(WCA),并对纤维材料过滤效率和压降进行了讨论。实验结果表明,经过表面处理后的仿生金属丝网过滤材料表面润湿特性得到了明显的改善,压降没有大幅度的增加,过滤效率得到了一定程度的提高。
