Superhydrophobic properties of multiple coupling

The phenomena that biological functions originate from biological coupling are the important biological foundation of multiple bionics and the significant discoveries in the bionic fields. In this paper, the multiple coupling characteristics and the superhydrophobic properties of the upper surface of the lotus leaf and artificial biomimetic surfaces were investigated through laser scanning confocal microscope, scanning electron microscopy and contact angle measurement. The results indicate that the multiple factors including morphology and/or microstructure and materials coupling by certain coupling mechanisms may carry out to produce superhydrophobic surfaces. By learning from and mimicking what was found, more bionic surfaces with similar properties can be created and find their applications where superhydrophobicity is required.
