Izindawo eziphezulu ze-hydrophobic zidalwe yi-Super hydrophobic coatings

I-Super-hydrophobic coatings ingenziwa ngezinto eziningi ezahlukene. Okulandelayo kuyaziwa izisekelo ezingase zibe khona zokunameka:

• I-Manganese oxide polystyrene (MnO2/PS) i-nano-composite
• I-Zinc oxide polystyrene (ZnO/PS) i-nano-composite
• Iqukethe i-calcium carbonate
• Izakhiwo ze-carbon nano-tube
• I-silica nano-coating

I-Super-hydrophobic coatings isetshenziselwa ukudala izindawo eziphezulu ze-hydrophobic. Uma amanzi noma into esuselwe emanzini ihlangana nalezi zindawo ezimboziwe, amanzi noma into "izohamba" phezulu ngenxa yezimpawu ze-hydrophobic zokumboza. I-Neverwet iyinalethi ye-superhydrophobic eyenziwe ngento esekelwe ku-silicon engase isetshenziselwe ukuhlanganisa yonke into kusukela ezicathulweni kuya kugesi womuntu siqu kuya endizeni.

I-silica-based coatings mhlawumbe ibiza kakhulu ukuyisebenzisa. Asekelwe kujeli futhi angasetshenziswa kalula ngokucwilisa into kujeli noma ngesifutho se-aerosol. Ngokuphambene, izinhlanganisela ze-oxide polystyrene ziqinile kakhulu kunezingubo ezisekelwe ku-gel, nokho inqubo yokufaka i-coating ihileleke kakhulu futhi iyabiza. Amashubhu e-carbon nano nawo ayabiza futhi kunzima ukuwakhiqiza ngalesi sikhathi. Ngakho-ke, ama-gel asekelwe ku-silica ahlala eyindlela enamandla kakhulu yezomnotho okwamanje.

I-coating idala ama-engeli okuxhumana aphezulu angama-degrees angu-160-175; ngaphezu kwamadigri angu-150 adingekayo ukuze kubonakale ukuthi i-subhydrophobic. Uketshezi, uwoyela, amagciwane ngisho neqhwa kushelela endaweni emboziwe cishe ngendlela yase-surreal. Embukisweni, abakhi be-Never-Wet bacwilisa i-smartphone esebenza ngokugcwele emanzini isigamu sehora kodwa yaphuma yomile ngokuphelele. Komunye umboniso, into eyacwiliswa emanzini isikhathi esingaphezu konyaka emanzini olwandle yatholwa yomile ngokuphelele futhi ayizange igqwale.

Izembatho ze-supe-hydrophobic zisetshenziselwa ukudala izinto ezilwa nokumanzisa, i-anti-icing, i-anti-corrosion, i-anti-bacterial kanye nokuzihlanza. Izindwangu ezinjengalezi zinamandla okwandisa ukusetshenziswa kwezomnotho, ukunciphisa ukungcola kanye nokukhula kwamagciwane, kanye nokwandisa isikhathi eside nokuqina kwemishini esengozini yokugqwala kanye nokulimala kwamanzi.
