Uphononongo lwe-Superhydrophobic Biomimetic Surfaces
Iipropathi zomphezulu wemathiriyeli zibaluleke kakhulu, kwaye abaphandi bazama zonke iintlobo zeendlela zokufumana umphezulu wezixhobo ezineempawu ezifunekayo. Ngophuhliso lobunjineli bebhayoloji, abaphandi banikela ingqalelo eyongeziweyo kumphezulu webhayoloji ukuze baqonde ukuba indalo inokusombulula njani iingxaki zobunjineli. Uphando olubanzi kumphezulu webhayoloji luveze ukuba le miphezulu ineempawu ezininzi ezingaqhelekanga. "I-lotus-effect" yinto eqhelekileyo ukuba indaloral ubume bomphezulu njengoko iplani isetyenziselwa ukuyilaFunda ngokugqithisileyo …
I-Superhydrophobic Surface inokulungiswa ngeendlela ezimbini
Abantu bayayazi ifuthe lelotus yokuzicoca iminyaka emininzi, kodwa abanako ukwenza izinto ezinjengomphezulu wegqabi lelotus. Ngokwendalo, i-superhydrophobic surface eqhelekileyo - uphononongo lufumene ukuba igqabi le-lotus, elakhiwe ngejometri ekhethekileyo yoburhalarhume kwindawo ephantsi yamandla eqinile idlala indima ebalulekileyo kwi-superhydrophobic.Ngokusekelwe kule migaqo, izazinzulu zaqala ukulinganisa le ndawo. Ngoku, uphando kumhlaba orhabaxa we-superhydrophobic lube luninzi lokugubungela. Kwimfuzaral, umphezulu we-superhydrophobicFunda ngokugqithisileyo …
Isiphumo sokuzicoca se-Super Hydrophobic Surface
I-Wettability yinto ebalulekileyo yendawo eqinileyo, echongwa yi-chemical composition kunye ne-morphology yomhlaba. Iimpawu ze-Super-hydrophilic kunye ne-super hydrophobic zezona ziqulatho eziphambili zezifundo ezihlaselayo. I-superhydrophobic (egxotha amanzi) ijini yangaphezulurally ibhekisa kumphezulu ukuba i-engile yoqhagamshelwano phakathi kwamanzi kunye nomphezulu ingaphezulu kwe-150 degrees. Into yokuba abantu bazi umphezulu we-superhydrophobic ubukhulu becala kumagqabi esityalo-igqabi lelotus, into “yokuzicoca”. Umzekelo, amathontsi amanzi anokuqengqeleka aqengqelekeFunda ngokugqithisileyo …
Umgaqo-siseko we-Hydrophobic / Super Hydrophobic Coatings
Iingubo eziqhelekileyo ze-sol-gel zalungiswa kusetyenziswa i-MTMOS kunye ne-TEOS njenge-silane precursors ukwenza inethiwekhi egudileyo, ecacileyo kunye nexineneyo ye-organic / inorganic network kwi-aluminium alloy substrate. Iingubo ezinjalo ziyaziwa ukuba zinamathele ngokugqwesileyo ngenxa yokukwazi ukwenza i-Al-O-Si ikhonkco kwi-coating/substrate interface.Isampula-II kolu phononongo imele i-coating ye-sol-gel eqhelekileyo. Ukuze kuncitshiswe amandla angaphezulu, kwaye ngoko ke ukwandisa i-hydrophobicity, sidibanise i-organo-silane equlethe ikhonkco ye-fluorooctyl, ukongeza kwi-MTMOS kunye ne-TEOS (isampuliFunda ngokugqithisileyo …
Imiphezulu ephezulu ye-hydrophobic yenziwe yi-Super hydrophobic coatings
Iingubo ze-Super-hydrophobic zingenziwa kwizinto ezininzi ezahlukeneyo. Ezi zilandelayo ziyaziwa iziseko ezinokwenzeka zokugquma: I-Manganese oxide polystyrene (MnO2 / PS) i-nano-composite Zinc oxide polystyrene (ZnO / PS) nano-composite I-precipitated calcium carbonate Izakhiwo zeCarbon nano-tube I-silica nano-coating I-Super-hydrophobic coatings isetyenziswa ukwenza iindawo eziphezulu ze-hydrophobic. Xa amanzi okanye into esekwe emanzini idibana nale miphezulu igqunyiwe, amanzi okanye into "iya kubaleka" kumphezulu ngenxa yeempawu ze-hydrophobic zokwaleka. Neverwet yiFunda ngokugqithisileyo …
Uphuhliso lwexesha elizayo lwepeyinti ye-hydrophobic
Ipeyinti yeHydrophobic ihlala ibhekisa kudidi oluphantsi lwamandla omgangatho ophantsi apho i-engile yoqhagamshelwano lwamanzi amileyo θ yokwambathisa kwindawo egudileyo ingaphezulu kwe-90 °, ngelixa ipeyinti ye-superhydrophobic luhlobo olutsha lokugquma oluneempawu ezikhethekileyo zomphezulu, okuthetha ukudibana kwamanzi isambatho esiqinileyo. I-engile ingaphezulu kwe-150 ° kwaye ihlala ithetha ukuba i-angle yokudibana kwamanzi ingaphantsi kwe-5 °. Ukususela kwi-2017 ukuya kwi-2022, imarike yepeyinti ye-hydrophobic iya kukhulaFunda ngokugqithisileyo …
