Phunziro la Superhydrophobic Biomimetic Surfaces
Zomwe zili pamwamba pazida ndi zofunika kwambiri, ndipo ofufuza amayesa njira zosiyanasiyana kuti apeze zinthu zomwe zili ndi zinthu zofunika. Ndi chitukuko cha uinjiniya wa bionic, ofufuza akuyang'ana kwambiri zachilengedwe kuti amvetsetse momwe chilengedwe chimatha kuthana ndi mavuto a uinjiniya. Kafukufuku wozama pazachilengedwe awonetsa kuti malowa ali ndi zinthu zambiri zachilendo. "Lotus-effect" ndizochitika zomwe chilengedwe chimachitaral mawonekedwe a pamwamba monga mapulaneti amagwiritsidwa ntchito popangaWerengani zambiri …
Superhydrophobic Surface Itha Kukonzedwa Ndi Njira Ziwiri
Anthu amadziwa zodzitchinjiriza zodzitchinjiriza kwa zaka zambiri, koma sangathe kupanga zinthu ngati tsamba la lotus. Mwachibadwa, mmene superhydrophobic padziko - kafukufuku anapeza kuti lotus tsamba, anamanga ndi geometry wapadera wa roughness mu otsika pamwamba mphamvu olimba pamwamba amatenga mbali yofunika kwambiri pa superhydrophobic.Kutengera mfundo zimenezi, asayansi anayamba kutsanzira pamwamba. Tsopano, kafukufuku woyipa wa superhydrophobic padziko lapansi wakhala akufotokozedwa kwambiri. Mu general, pamwamba pa hydrophobicWerengani zambiri …
Kudzitchinjiriza Zochita za Super Hydrophobic Surface
Kunyowa ndi chinthu chofunikira kwambiri chapamwamba, chomwe chimatsimikiziridwa ndi kapangidwe ka mankhwala ndi morphology ya pamwamba. Mawonekedwe apamwamba kwambiri a hydrophilic ndi apamwamba kwambiri a hydrophobic ndizomwe zili mumaphunziro owononga. Jini yapamtunda ya superhydrophobic (yoletsa madzi).rally amatanthauza pamwamba kuti ngodya yolumikizana pakati pa madzi ndi pamwamba ndi yayikulu kuposa madigiri 150. Zomwe anthu amadziwa kuti superhydrophobic pamwamba imachokera ku masamba a zomera - tsamba la lotus, "kudziyeretsa" chodabwitsa. Mwachitsanzo, madontho amadzi amatha kugudubuzaWerengani zambiri …
Mfundo ya Hydrophobic/Super Hydrophobic Coatings
Zovala zodziwika bwino za sol-gel zidakonzedwa pogwiritsa ntchito MTMOS ndi TEOS monga zoyambira za silane kuti apange maukonde osalala, omveka bwino komanso owoneka bwino a organic / inorganic network pagawo la aluminium alloy. Zovala zoterezi zimadziwika kuti zimakhala ndi zomatira bwino kwambiri chifukwa cha kuthekera kwawo kupanga maulumikizi a Al-O-Si pa mawonekedwe opaka / gawo lapansi.Sample-II mu phunziroli ikuyimira chojambula chodziwika bwino cha sol-gel. Kuti tichepetse mphamvu zapamtunda, ndikuwonjezera hydrophobicity, tidaphatikiza organo-silane yokhala ndi unyolo wa fluorooctyl, kuphatikiza MTMOS ndi TEOS (zitsanzo).Werengani zambiri …
Malo apamwamba a hydrophobic amapangidwa ndi zokutira za Super hydrophobic
Zovala za Super-hydrophobic zitha kupangidwa kuchokera kuzinthu zosiyanasiyana. Zotsatirazi ndizomwe zimadziwika kuti ndizoyambira zokutira: Manganese oxide polystyrene (MnO2/PS) nano-composite Zinc oxide polystyrene (ZnO/PS) nano-composite Precipitated calcium carbonate Kaboni nano-chubu silika nano-❖ kuyanika Super-hydrophobic zokutira amagwiritsidwa ntchito. kuti apange malo apamwamba kwambiri a hydrophobic. Madzi kapena chinthu chochokera m'madzi chikakumana ndi malo okutidwawa, madzi kapena chinthucho "chimachoka" pamtunda chifukwa cha mawonekedwe a hydrophobic a zokutira.

Chiyembekezo chamtsogolo cha utoto wa hydrophobic
Utoto wa Hydrophobic nthawi zambiri umatanthawuza gulu la zokutira zotsika pansi pomwe madzi osasunthika olumikizana ndi ngodya θ ya zokutira pamtunda wosalala ndi wamkulu kuposa 90 °, pomwe utoto wa superhydrophobic ndi mtundu watsopano wa zokutira wokhala ndi mawonekedwe apadera apamwamba, kutanthauza kukhudzana ndi madzi. zokutira zolimba. Ngodyayo ndi yayikulu kuposa 150 ° ndipo nthawi zambiri imatanthauza kuti kutsika kwamadzi ndikochepera 5 °. Kuyambira 2017 mpaka 2022, msika wa utoto wa hydrophobic udzakulaWerengani zambiri …
