b) Nano titanium hmoov raws li ib qho inorganic muab tub lim tuaj yeem txhim kho cov khoom siv kho tshuab thiab corrosion tsis kam ntawm epoxy resin.Cov hmoov nano-titanium siv hauv qhov kev sim muaj qhov loj me me ntawm 100nm.Cov txiaj ntsig kev ntsuam xyuas pom tau tias qhov kev tiv thaiv corrosion ntawm epoxy-hloov nano-titanium hmoov txheej thiab polyamide-hloov nano-titanium hmoov txheej tau txhim kho los ntawm 1-2 Magnitude.Optimize epoxy resin hloov kho thiab dispersion txheej txheem.Ntxiv 1% hloov kho nano titanium hmoov rau epoxy resin kom tau txais kev hloov kho nano titanium hmoov txheej.Cov txiaj ntsig ntawm EIS cov qhabnias qhia tau hais tias qhov impedance modulus ntawm qhov tsawg-zaus kawg ntawm txheej tseem nyob ntawm 10-9Ω.cm ~ 2 tom qab immersion rau 1200h.Nws yog 3 qhov kev txiav txim siab ntau dua li epoxy varnish.
2) Nano zinc oxide
Nano-ZnO yog cov khoom siv nrog ntau yam khoom zoo heev thiab tau siv dav hauv ntau qhov chaw.Nws muaj cov tshuaj tua kab mob zoo tiv thaiv kab mob.titanate coupling tus neeg sawv cev HW201 tuaj yeem siv los hloov kho qhov chaw ntawm nano-ZnO.Cov ntaub ntawv hloov kho nano yog siv los ua cov khoom ntim rau hauv epoxy resin txheej txheej txheej los npaj peb hom nano-marine antifouling txheej nrog cov kab mob bactericidal.Los ntawm kev tshawb fawb, nws tau pom tias qhov sib txawv ntawm kev hloov kho nano-ZnO, CNT thiab graphene tau txhim kho zoo.
3) Carbon-based nanomaterials
Cov pa roj carbon nanotubes (CNT)thiab graphene, raws li cov ntaub ntawv tawm los ntawm cov pa roj carbon monoxide, muaj cov khoom zoo heev, tsis muaj tshuaj lom, thiab tsis ua phem rau ib puag ncig.Ob leeg CNT thiab graphene muaj cov kab mob bactericidal, thiab CNT tuaj yeem txo qhov tshwj xeeb ntawm lub zog ntawm txheej.Siv silane coupling tus neeg sawv cev KH602 los hloov kho qhov chaw ntawm CNT thiab graphene los txhim kho lawv cov stability thiab dispersibility hauv txheej txheej.Cov khoom siv nano hloov kho tau siv los ua cov khoom ntim rau hauv epoxy resin txheej txheej txheej los npaj peb hom nano-marine antifouling coatings nrog cov kab mob bactericidal.Los ntawm kev tshawb fawb, nws tau pom tias qhov sib txawv ntawm kev hloov kho nano-ZnO, CNT thiab graphene tau txhim kho zoo.
4) Anticorrosive thiab antibacterial plhaub core nanomaterials
Siv cov khoom siv tshuaj tua kab mob super ntawm cov nyiaj thiab lub plhaub ntxeem tau ntawm silica, tsim thiab sib dhos ntawm cov tub ntxhais-plhaub qauv nano Ag-SiO2;Kev tshawb fawb los ntawm nws cov bactericidal kinetics, bactericidal mechanism thiab anti-corrosion kev ua tau zoo, ntawm cov nyiaj core Qhov loj yog 20nm, lub thickness ntawm nano-silica plhaub txheej yog hais txog 20-30nm, cov nyhuv antibacterial yog pom tseeb, thiab cov tus nqi ua tau zoo dua.
5) Nano cuprous oxide antifouling khoom
Tom ntej: Cuprous oxide CU2Oyog tus neeg sawv cev antifouling nrog keeb kwm ntev ntawm daim ntawv thov.Qhov tso tawm tus nqi ntawm nano-sized cuprous oxide yog qhov ruaj khov, uas tuaj yeem txhim kho cov kev ua haujlwm ntawm cov txheej txheem.Nws yog ib qho zoo anti-corrosion txheej rau cov nkoj.Qee cov kws tshaj lij txawm kwv yees tias nano cuprous oxide tuaj yeem ua kev kho mob ntawm cov pa phem hauv ib puag ncig.
