Abstract: Nanosecond laser was used to construct meshes with different line spacing on the surface of copper substrate to create different surface roughness. The influence of nanosecond laser microstructure on inert wetting and reactive wetting of copper was studied by using modified sessile drop method. The results showed that the different types of meshes did not cause asymmetric droplet, and the inert wetting was consistent with Wenzel model, while the reactive wetting results deviated from the model. In the inert wettable system, as predicted by Wenzel model, the increased roughness would promote the final wettability. The deviation of reactive wetting can be attributed to the fact that the asperities of the rough surface prevents the triple line from moving, and thus the increase of the roughness does not promote the wettability.
