The unique living environment of
aquatic plants makes them produce
many fantastic properties different from land ones. For instance,
the leaves of Myriophyllum spicatum show excellent hydrophobicity and aerophily characteristics. In
this paper, the abundant morphological structure, composition, and
aerophily properties of Myriophyllum spicatum leaves are revealed. The contact angle of the leaf surface can reach
122° in air, exhibiting wonderful gas collection ability under
water. The results showed that the aerophily of the leaves is attributed
to the multistage micro–nanostructure and waxy layer on the
surface. The gas transportation toward the tips of leaves is based
on the void gradient formed by the nanoscale morphology at different
growth stages and the buoyancy as well. These features provide bionic
experience for gas collection, bubble transportation, and liquid resistance
reduction in water environments.
