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. Super-hydrophilic a me super hydrophobic ʻO nā hiʻohiʻona ili 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. Ua ʻike ka poʻe i ka ʻili superhydrophobic mai nā lau mea kanu - ʻili lau lotus, "hoʻomaʻemaʻe ponoʻī". No ka laʻana, hiki i nā kulu wai ke ʻōwili a ʻōwili ma luna o ka ʻili o ka lau lotus, ʻoiai inā e ninini ʻia kekahi o ka wai i loko o ka lau, ʻaʻole ia e waiho i kahi pala ma nā lau. ʻO kēlā mau hiʻohiʻona lau lotus unstained i kapa ʻia ʻo "self-cleaning" hopena.

ʻO Lotus hopena - Super hydrophobic kumu

ʻOiai ua ʻike mua ka poʻe i ka hopena "hoʻomaʻemaʻe ponoʻī" i ka lau lau lotus, akā ʻaʻole hiki ke hoʻomaopopo i ka mea huna o ka ʻili lau lotus. A hiki i ka makahiki 1990, ua ʻike mua ʻia nā ʻepekema Kelemania ʻelua me kahi microscope electron scanning, ka microstructure o ka ʻili lau lotus, ʻo ia ka hopena "hoʻomaʻemaʻe ponoʻī" i hana ʻia e kahi micron mastoid a me ka lau lotus ma luna o ka ʻili. Ma hope mai, ua kālailai ʻia nā ʻepekema ʻepekema i ka hohonu o ka ʻili o ka ʻano micron lau lotus a ʻike ʻia aia kahi nanostructures i ka mastoid lau lau lotus, ʻoiai ʻo kēia ʻano pālua o ka micron a me ka nano-structure ke kumu kumu o ka "hoʻomaʻemaʻe ponoʻī" i loko. he ili lau lotus.

No ke aha e hiki ai i kahi ʻili "ʻeleʻele" ke hana i ka superhydrophobic

No ka ʻili paʻa hydrophobic, inā he liʻiliʻi ka liʻiliʻi o ka ili, e "hele ʻia" kekahi o ka ea ma waena o ka wai a me nā ʻili paʻa, e alakaʻi ana i nā kulu wai i ka hapa nui o ka hoʻopili ʻana me ka ea, akā ʻo ka hoʻopili pololei ʻana me nā ʻili paʻa. emi iho. Ma muli o ke ʻano o ka ʻili o nā kulu wai i ke ʻano a kokoke i ka spherical ka ʻili i hoʻopili ʻia, ʻo ka huina pili a hiki i 150 degere, a hiki i nā kulu o ka wai ma luna o ka ʻili ke manuahi e ʻōwili.

ʻOiai me kekahi o nā mea lepo ma luna o ka ʻili, e kaʻa lākou i nā kulu, no laila e loaʻa i ka ʻili kahi hiki ke "hoʻomaʻemaʻe ponoʻī". Ua kapa ʻia kēia ʻili me ka huina pili i ʻoi aku ma mua o 150 degere "super-hydrophobic surface", a ʻo ke kihi pili o ka gene.ral ʻoi aku ka nui o ka hydrophobic ma mua o 90 degere.

I ka natural honua, koe wale nō ka mana o ka lau lotus "hoʻomaʻemaʻe iā ia iho", aia kekahi mau mea e like me ka laiki, nā mea kanu kalo a me nā hulu manu e like me nā manu. , a me ka pale ʻana i ke komo ʻana o nā pathogens. No ka mea me ka pathogen i ka ʻili lau, e holoi ʻia. No laila e like me kēia, ʻo ka mea kanu lotus e ulu ana i kahi ʻano "palapala" ʻaʻole maʻalahi ka maʻi, ʻo ke kumu koʻikoʻi ma muli o kēia hiki ke hoʻomaʻemaʻe iā ia iho.
