Thaum lub caij ntuj nag dej nyab loj xyoo 1998, cov dej khov ua rau ntawm cov kab hluav taws xob thiab cov ncej tau coj sab qaum teb Tebchaws Meskas thiab sab qab teb Canada mus rau qhov chaw nres tsheb, ua rau ntau tus neeg txias thiab tsaus rau hnub lossis ntau lub lis piam.Txawm hais tias nws yog cua turbines, hluav taws xob yees, drones lossis dav hlau tis, de-icing feem ntau tso siab rau txoj kev siv sijhawm, kim thiab / lossis siv ntau lub zog thiab ntau yam tshuaj.Tab sis saib ntawm qhov xwm txheej, McGill cov kws tshawb fawb xav tias lawv tau pom txoj hauv kev tshiab los daws qhov teeb meem.Lawv tau txais kev tshoov siab los ntawm cov tis ntawm gentoo penguins ua luam dej hauv dej khov ntawm Antarctica, thiab lawv cov plaub hau tsis khov txawm tias qhov kub ntawm sab nraud yog qis dua khov.
Peb thawj zaug tshawb xyuas cov khoom ntawm cov nplooj nplooj, uas zoo heev ntawm kev tshem tawm dej, tab sis nws tau pom tias lawv tsis tshua muaj txiaj ntsig ntawm kev tshem dej khov, "Ann Kitzig, uas tau nrhiav kev daws teeb meem rau yuav luag ib xyoo caum thiab yog tus pab xibfwb. .Tus kws kho mob ntawm Chemical Engineering ntawm McGill University, Tus Thawj Coj ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb Biomimetic Surface Engineering: "Nws tsis yog txog thaum peb pib tshawb xyuas cov khoom ntawm penguin feathers uas peb nrhiav tau ib yam khoom tshwm sim uas ib txhij tso dej thiab dej khov.”
Covduabnyob rau sab laug qhia tau hais tias lub microstructure ntawm ib tug penguin feather (qhov ze-up ntawm 10 micron ntxig sib raug rau 1/10 ntawm qhov dav ntawm tib neeg cov plaub hau kom muaj kev nkag siab ntawm nplai).Cov barbs thiab twigs yog lub hauv paus stems ntawm branching feathers.."Hooks" yog siv los koom nrog cov plaub hau plaub hau ua ke los tsim lub cushion.Ntawm sab xis yog ib daim ntaub stainless hlau hlau uas cov kws tshawb fawb tau dai kom zoo nkauj nrog nanogrooves, rov tsim cov hierarchy ntawm penguin feather qauv (xov hlau nrog nanogrooves saum).
"Peb pom tias cov txheej txheem hierarchical ntawm cov plaub lawv tus kheej muab cov khoom tso dej, thiab lawv cov serrated nto txo ​​cov dej khov," piav qhia Michael Wood, cov tub ntxhais kawm tiav tsis ntev los no ua haujlwm nrog Kitzig thiab ib tus kws sau ntawv ntawm txoj kev tshawb no.Kab lus tshiab hauv ACS Applied Material Interfaces."Peb muaj peev xwm rov ua dua cov teebmeem no nrog laser-txiav woven hlau mesh."
Kitzig ntxiv: "Nws yuav zoo li tsis txaus ntseeg, tab sis tus yuam sij rau kev sib cais cov dej khov yog tag nrho cov pores hauv cov mesh uas nqus dej hauv cov dej khov.Cov dej hauv cov pores thaum kawg khov, thiab thaum nws nthuav dav, nws tsim cov kab nrib pleb, ib yam li koj xav nyob hauv tub yees.Nws zoo ib yam li pom nyob rau hauv lub thawv dej khov.Peb xav tau kev siv zog me ntsis los tshem cov dej khov los ntawm peb lub mesh vim tias cov kab nrib pleb hauv txhua qhov ntawm cov qhov no zoo li mus rau qhov chaw ntawm cov xov hlau braided. "
Cov kws tshawb fawb tau sim cov stenciled nto nyob rau hauv lub qhov cua thiab pom tias kev kho mob yog 95% zoo dua ntawm kev tiv thaiv icing dua unwrapped polished stainless hlau los xij.Txij li tsis muaj kev kho tshuaj lom neeg yuav tsum tau ua, txoj kev tshiab muaj peev xwm kho tsis tau cov kev daws teeb meem ntawm kev tsim dej khov ntawm cov cua turbines, yees, cov kab hluav taws xob thiab cov drones.
"Raws li tus naj npawb ntawm cov neeg caij dav hlau txoj cai lij choj thiab cov kev pheej hmoo cuam tshuam, nws tsis zoo li cov tis dav hlau yuav tsuas yog qhwv hauv cov hlau mesh," Kitzig ntxiv."Nws muaj peev xwm, txawm li cas los xij, muaj ib hnub saum npoo ntawm lub dav hlau tis yuav muaj qhov kev ntxhib los mos uas peb tab tom kawm, thiab txij li cov txheej txheem de-icing ib txwm ua haujlwm ua ke ntawm lub tis nto, de-icing yuav tshwm sim los ntawm fusing penguin tis.kev tshoov siab los ntawm kev ntxhib los mos ntawm qhov chaw. "
"Txhim kho qhov chaw tiv thaiv icing raws li kev ua haujlwm dual - microstructure-induced ice flaking nrog nanostructure-enhanced water repellency overlay", Michael J. Wood, Gregory Brock, Juliette Debre, Philippe Servio thiab Anne-Marie Kitzig hauv ACS Appl.alma mater.interface
McGill University, nrhiav tau nyob rau hauv 1821 hauv Montreal, Quebec, yog tus naj npawb ib lub tsev kawm ntawv hauv Canada.McGill University yog qhov tsis tu ncua ntawm cov tsev kawm qib siab tshaj plaws hauv tebchaws thiab thoob ntiaj teb.Nws yog lub tsev kawm ntawv muaj npe nrov hauv ntiaj teb ntawm kev kawm qib siab nrog kev tshawb fawb txog peb lub tsev kawm ntawv, 11tsev kawm ntawv qib siab, 13 lub tsev kawm qib siab tshaj lij, 300 txoj kev kawm thiab ntau dua 40,000 tus tub ntxhais kawm, suav nrog ntau dua 10,200 cov tub ntxhais kawm tiav.McGill nyiam cov tub ntxhais kawm los ntawm ntau dua 150 lub teb chaws, thiab nws 12,800 cov tub ntxhais kawm thoob ntiaj teb suav nrog 31% ntawm cov tub ntxhais kawm lub cev.Ntau tshaj li ib nrab ntawm McGill cov tub ntxhais kawm hais tias lawv thawj hom lus tsis yog lus Askiv, thiab kwv yees li 19% ntawm lawv hais lus Fab Kis ua thawj hom lus.
