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 njengeplani isetyenziselwa ukuyila kunye nokwenza umphezulu wemathiriyeli yobunjineli. I-binary microstructure ye-lotus surface endows super-hydrophobicity, enokuthi ivumelane neemeko zokusingqongileyo kakuhle. Kwiminyaka yakutshanje, umphezulu we-superhydrophobic biomimetics ziye zaphononongwa kakhulu ngenxa yemfuneko yezinto ezizicoca ngokwazo, isixhobo solwelo oluncinci kunye nezinye.

Imiphezulu ye-bio-inspired superhydrophobic surfaces ilungiswe ngeendlela ezininzi ngokwemigaqo yomzimba kunye neekhemikhali, ezifana ne-lithography, indlela ye-template, i-sublimation, iindlela ze-electrochemical, iindlela ze-layer-by-layer, indlela esezantsi-phezulu yokwenza i-nano-arrays njalo njalo. . Nangona kunjalo, abaphandi bahlala besenza iifilimu ze-hydrophobic kwizinto zetsimbi kunye nomphezulu wezinto ezingaphili kunye nepropathi ezinzileyo yeekhemikhali. Ngenxa yoko, isinyithi esisebenzayo kunye nomphezulu we-alloy yazo ayiphandwa kakhulu. IMagnesium yenye yezona zinto zikhaphukhaphu zobunjineli. Ke, kulindeleke ukuba i-magnesium kunye ne-alloys yayo isetyenziswe kwi-aerospace, inqwelomoya, iimoto kunye nosetyenziso lukaloliwe.

Ukugquma kwe-hydrophobic kuya kuba yitekhnoloji ethembisayo yokuphucula ukusebenza komphezulu. Jiang et al. [1] yenziwe i-super-hydrophobic biomimetic surface kwi-alloy ye-Mg-Li ngokusebenzisa i-chemical etching, ilandelwa yinkqubo yokuntywiliselwa kunye ne-annealing kusetyenziswa iimolekyuli ze-fluoroalkylsilane (FAS). [2] yenza i-super-hydrophobic surface kwi-alloy ye-magnesium ngokuntywiliselwa kwisisombululo se-cerium nitrate yamanzi (i-20 min). Jun et al. [3] idale indawo ezinzileyo ye-biomimetic super-hydrophobic kwi-alloy ye-magnesium eyenziwe yi-microarc oxidation pretreatment kwaye ilandelwa yi-chemical modification esekelwe kwi-lotus effect. Li et al. [4] walungisa magnesium films obhityileyo nge bias magnetron sputtering.
