Barashada Dusha sare ee Biomimetic Superhydrophobia
Qalabka dusha sare ee alaabadu waa mid aad muhiim u ah, cilmi-baarayaashuna waxay isku dayaan dhammaan noocyada hababka si ay u helaan sagxadaha alaabta leh guryaha loo baahan yahay. Iyadoo horumarinta injineernimada bionic, cilmi-baarayaashu waxay fiiro gaar ah u siinayaan dusha bayoolojiga si ay u fahmaan sida dabeecadda u xallin karto dhibaatooyinka injineernimada. Baadhitaano ballaadhan oo lagu sameeyay sagxadaha bayooloji waxay daaha ka qaadeen in dushan ay leeyihiin waxyaabo badan oo aan caadi ahayn. "Saamaynta-lotus" waa dhacdo caadi ah oo uu natu leeyahayral qaab dhismeedka dusha sida blueprint waxaa loo isticmaalaa in lagu naqshadeeyoAkhri wax dheeraad ah …
Dusha sare-hydrophobic waxaa lagu diyaarin karaa laba qaab
Dadku waxay yaqaaniin saamaynta is-nadiifinta nacnaca sanado badan, laakiin ma samayn karaan walxaha sida caleenta nasinta. Dabeecad ahaan, dusha sare ee superhydrophobic - cilmi-baaris ayaa lagu ogaaday in caleenta lotus, oo lagu dhisay joomatari gaar ah oo qallafsanaanta tamarta dusha hoose ee adag ee dusha sare ayaa door muhiim ah ka ciyaara superhydrophobic. Iyada oo ku saleysan mabaadi'da, saynisyahannadu waxay bilaabeen inay ku daydaan dusha sare. Hadda, cilmi-baaris lagu sameeyay dusha sare ee biyo-cabbiyeedka qallafsan waxay ahayd caymis badan.

Saamaynta is-nadiifinta ee dusha sare ee Hydrophobic
Qoyaanka waa muuqaal muhiim ah oo ka mid ah dusha adag, kaas oo lagu go'aamiyo isku-dhafka kiimikada iyo qaabka dusha sare. Super-hydrophilic iyo sifooyinka dusha sare ee hydrophobic ayaa ah waxyaabaha ugu muhiimsan ee daraasadaha duullaanka ah. Hidde-sidayaasha sare-hydrophobic (biyaha-celiya).rally waxa ay tilmaamaysaa oogada in xagal xidhiidhka u dhexeeya biyaha iyo korka uu ka weyn yahay 150 darajo. Dadku waxay og yihiin in dusha sare ee superhydrophobic ay inta badan ka timid caleemaha dhirta - dusha caleen lotus, ifafaale "is-nadiifinta".

Mabaadi'da Dahaarka Hydrophobic/Super Hydrophobic
Dahaarka sol-gel ee caadiga ah ayaa la diyaariyey iyadoo la adeegsanayo MTMOS iyo TEOS sidii horudhac silane ah si loo sameeyo shabakad siman, cad oo cufan oo dabiici ah / aan dabiici ahayn oo ku taal substrate alloy aluminium ah. Dahaarka noocan oo kale ah waxaa loo yaqaanaa in ay leeyihiin adhesion aad u fiican sababtoo ah awoodda ay u leeyihiin in ay sameeyaan isku-xirnaanta Al-O-Si ee isku-xidhka daboolka / substrate-ka.Sample-II ee daraasaddan ayaa ka dhigan sida caadiga ah ee sol-gel. Si loo dhimo tamarta dusha sare, oo markaa loo kordhiyo hydrophobicity, waxaan ku darnay organo-silane oo ka kooban silsilad fluorootyl ah, marka lagu daro MTMOS iyo TEOS (muunad).Akhri wax dheeraad ah …
Dusha sare ee hydrophobic waxaa abuuray dahaarka Super hydrophobic
Dahaarka Super-hydrophobic waxaa laga samayn karaa waxyaabo badan oo kala duwan. Kuwa soo socda ayaa la og yahay saldhigyada suurtogalka ah ee daahan: Manganese oxide polystyrene (MnO2/PS) nano-composite Zinc oxide polystyrene (ZnO/PS) nano-composite calcium carbonate Precipitated calcium carbonate Kaarbon nano-tube qaab-dhismeedka Silica nano-dahaarka Super-hydrophobic ayaa la isticmaalaa. si loo abuuro dusha sare ee hydrophobic. Marka biyaha ama walaxda biyaha ku salaysani ay la kulmaan meelahan daboolan, biyaha ama walaxda ayaa "ka dareeri doona" dusha sare sababtoo ah sifooyinka hydrophobic ee daahan.

Rajada horumarinta mustaqbalka ee rinjiga hydrophobic
Rinjiga Hydrophobic wuxuu inta badan tixraacaa fasalka dahaarka tamarta hoose ee hoose halkaas oo xagasha xiriirka biyaha ee θ ee daahanka dusha siman uu ka weyn yahay 90 °, halka rinjiga superhydrophobic uu yahay nooc cusub oo daahan ah oo leh sifooyin dusha sare ah, taasoo la micno ah xiriir biyo leh daahan adag. Xagasha ayaa ka weyn 150° oo badiyaa waxay la macno tahay in xagasha xidhiidhka biyaha uu ka yar yahay 5°.
