Abstract :
The wide application of superhydrophobic materials is mainly hindered by the poor mechanical robustness and complicatedpreparation method. To overcome these problems, we tried to make a combination of hierarchical and self-similar structure bythe means of a simple spraying method. By adding nanofiller (carbon nanotube) and microfiller (graphite powder and expandedgraphite), the hierarchical structure was constructed. By further doping thefillers in the commercial asphalt uniformly, the self-similar structure was prepared. Based on the aforementioned work, the as-prepared sample could withstand the sandpaperabrasion for 12.00 m under 4.90 kPa. Moreover, this superhydrophobic coating demonstrated good conductivity, superior self-cleaning property, and excellent corrosion resistance. The integration of conductivity with the superhydrophobicity might opennew avenues for ground grid applications.
