Nettet10. mar. 2011 · Here, inspired by natural superhydrophobic surfaces (e.g., the lotus leaf), a molten-volcanic-ash-phobic TBC, which provides a large possibility to eliminate molten ash issues of TBCs, is developed. NettetLotus leaves have become an icon for superhydrophobicity and self-cleaning surfaces, and have led to the concept of the ‘Lotus effect’. Although many other plants have superhydrophobic surfaces with almost similar contact angles, the lotus shows better stability and perfection of its water repellency. Here, we compare the relevant ...
Nettet27. sep. 2024 · The lotus leaf was described by the ancient Chinese as “dirt-free plant rising from soil”, which is the most typical super-hydrophobic surface of plants (Latthe et al., 2014), and it is also one of the earliest research goals of human beings, which is why the “lotus leaf effect” is still synonymous with superhydrophobic characteristics.
