Ucwaningo lwe-Superhydrophobic Biomimetic Surfaces
Izakhiwo ezingaphezulu zezinto ezisetshenziswayo zibaluleke kakhulu, futhi abacwaningi bazama zonke izinhlobo zezindlela zokuthola izinto ezingaphezulu ezinezakhiwo ezidingekayo. Ngokuthuthuka kobunjiniyela be-bionic, abacwaningi banaka kakhulu indawo yebhayoloji ukuze baqonde ukuthi imvelo ingazixazulula kanjani izinkinga zobunjiniyela. Uphenyo olubanzi endaweni yebhayoloji luveze ukuthi lezi zindawo zinezinto eziningi ezingajwayelekile. I-"lotus-effect" yinto evamile eyenziwa yi-natural isakhiwo esingaphezulu njengepulani sisetshenziselwa ukuklamaFunda kabanzi …
I-Superhydrophobic Surface Ingalungiswa Ngezindlela Ezimbili
Abantu bayawazi umphumela we-lotus wokuzihlanza iminyaka eminingi, kodwa abakwazi ukwenza izinto njengoba iqabunga le-lotus livela. Ngokwemvelo, i-superhydrophobic surface ejwayelekile - ucwaningo lwathola ukuthi iqabunga le-lotus, elakhiwe ngejiyomethri ekhethekile yokuqina endaweni ephansi yamandla eqinile idlala indima ebalulekile ku-superhydrophobic.Ngokusekelwe kulezi zimiso, ososayensi baqala ukulingisa le ndawo. Manje, ucwaningo mayelana ne-superhydrophobic surface selumboziwe kakhulu. Kufuzoral, i-superhydrophobic surfaceFunda kabanzi …
Umthelela wokuzihlanza we-Super Hydrophobic Surface
Ukumanzisa kuyisici esibalulekile sendawo eqinile, enqunywa ukwakheka kwamakhemikhali kanye ne-morphology yendawo. Izici ze-Super-hydrophilic kanye ne-super hydrophobic ziwukuqukethwe okuyinhloko kwezifundo ezihlaselayo. I-superhydrophobic (exosha amanzi) isakhi sofuzo sangaphezulurally ibhekisela endaweni ukuthi i-engeli yokuthintana phakathi kwamanzi nengaphezulu ingaphezu kwamadigri angu-150. Abantu bazi ukuthi i-superhydrophobic surface iphuma emaqabunga ezitshalo - i-lotus leaf surface, into "yokuzihlanza". Isibonelo, amaconsi amanzi angakwazi ukugoqaFunda kabanzi …
Isimiso se-Hydrophobic/Super Hydrophobic Coatings
Izembatho ezivamile ze-sol-gel zalungiswa kusetshenziswa i-MTMOS ne-TEOS njengama-silane precursors ukuze kwakheke inethiwekhi ye-organic/inorganic/inorganic network ebushelelezi, ecacile futhi eminyene ku-substrate ye-aluminium alloy. Izembatho ezinjalo zaziwa ngokunamathela okuhle kakhulu ngenxa yekhono lazo lokwakha izixhumanisi ze-Al-O-Si ku-interface yokugqoka/i-substrate.Isampula-II kulolu cwaningo imelela ukugqoka okunjalo okujwayelekile kwe-sol-gel. Ukuze kwehliswe amandla angaphezulu, futhi ngalokho kwandise i-hydrophobicity, sihlanganise i-organo-silane equkethe iketango le-fluorooctyl, ngaphezu kwe-MTMOS ne-TEOS (isampulaFunda kabanzi …
Izindawo eziphezulu ze-hydrophobic zidalwe yi-Super hydrophobic coatings
I-Super-hydrophobic coatings ingenziwa ngezinto eziningi ezahlukene. Okulandelayo yizisekelo ezaziwayo ezingaba khona zokumbozwa: I-Manganese oxide polystyrene (MnO2/PS) nano-composite Zinc oxide polystyrene (ZnO/PS) nano-composite I-precipitated calcium carbonate Izakhiwo ze-Carbon nano-tube I-silica nano-coating Kusetshenziswa i-Super-hydrophobic coatings. ukwakha izindawo eziphakeme kakhulu ze-hydrophobic. Uma amanzi noma into esuselwe emanzini ihlangana nalezi zindawo ezimboziwe, amanzi noma into "izohamba" phezulu ngenxa yezimpawu ze-hydrophobic zokumboza. I-Neverwet iFunda kabanzi …
Amathemba entuthuko yesikhathi esizayo kapende we-hydrophobic
Upende we-hydrophobic uvame ukubhekisela ekilasini lezingubo zamandla aphansi angaphezulu lapho i-engeli yokuthintana kwamanzi emile θ ye-coating endaweni ebushelelezi ingaphezu kuka-90°, kanti upende we-superhydrophobic uwuhlobo olusha lokumboza olunezici ezikhethekile ezingaphezulu, okusho ukuthintana kwamanzi isambatho esiqinile. I-engeli inkulu kuno-150° futhi ngokuvamile isho ukuthi i-engeli yokuxhumana namanzi ingaphansi kuka-5°. Kusukela ngo-2017 kuya ku-2022, imakethe yokupenda ye-hydrophobic izokhula ngoFunda kabanzi …
