Surface preparation method capable of preparing various nanowire structures

The invention discloses a surface preparation method capable of preparing various nanowire structures, and belongs to the technical field of surface treatment. According to the method, by means of a template-assisted electroplating method, various structural appearances such as an upright type, an agglomeration type and a round pit type can be formed by changing the interval and aperture of template holes and the electroplating time, and the structure height and included angle of the upright type and the agglomeration type can be changed. Nanowires are 4-50 microns high, the center distance ofthe nanowires is 60-500 nm, and the diameter of the nanowires is 5-400 nm. The surface appearances prepared through the preparation method are controllable, the structural form is diversified and cross-scale, the upright type and the agglomeration type can be used for condensation, and the round pit type can be applied to the field of phase-change heat transfer such as boiling. 一种能制备多种纳米线结构的表面制备方法，其属于表面处理技术领域。该方法利用模板辅助的电
