To endow strain sensors with superhydrophobicity may be a promising approach to improve the infrastructure safety in harsh environments.
Abstract Although superhydrophobic materials have attracted much research interest in anti-icing, some controversy still exists. In this research, we report a cost-effective method used to verify the contribution of area fraction ice adhesion strength. We tried partially-embed silica nanoparticles into microscale fabrics commercial polyamide mesh. Then, could be determined by altering mesh size. Generally, strength decreases as decreases. An ∼1.9 kPa and delayed freezing time ∼1048 s can...
