In this work we investigated the effects of surface modification on the capillary rise of the copper braids. The hydrophobic surfaces of the copper braids were modified to be hydrophilic. Significant improvements in capillary rise were then observed after surface modification. The effects of gravity on the capillary rise were also investigated. In contrast to the constant vertical capillary rise for the hollow tubes, the experimental results show that the vertical capillary rise of the copper braids decreases with increasing inclined angles. The finite impregnation distances in the copper braids placed horizontally are also observed. A revised model is proposed to explain such characteristics of copper braids. |
