Haʻawina o Superhydrophobic Biomimetic Surfaces
He mea koʻikoʻi ka waiwai o ka ʻili o nā mea, a ke hoʻāʻo nei nā mea noiʻi i nā ʻano hana āpau e kiʻi i nā ʻili o nā mea me nā waiwai pono.

Hiki ke hoʻomākaukau ʻia ka ʻili Superhydrophobic e nā ʻano ʻelua
Ua ʻike ka poʻe i ka hopena lotus hoʻomaʻemaʻe ponoʻī no nā makahiki he nui, akā ʻaʻole hiki ke hana i ka mea e like me ka lau lau lotus.

Hoʻomaʻemaʻe iā ia iho i ka Super Hydrophobic Surface
ʻO ka wettability kahi hiʻohiʻona koʻikoʻi o ka ʻili paʻa, i hoʻoholo ʻia e ka haku melemele a me ka morphology o ka ʻili. ʻO nā hiʻohiʻona super-hydrophilic a me super hydrophobic ka mea nui o nā haʻawina invasive. ʻO ke ʻano o ka ʻili superhydrophobic (wai-repellent).rally pili i ka ili i ʻoi aku ka nui o ka huina pili ma waena o ka wai a me ka ʻili ma mua o 150 degere.
