Marine biological fouling inogona kukonzera kukuvadzwa kwezvinhu zveinjiniya zvemugungwa, kuderedza hupenyu hwebasa rezvinhu, uye kukonzera kurasikirwa kwakanyanya kwehupfumi uye tsaona dzakaipisisa.Kushandiswa kwe-anti-fouling coatings ndiyo inowanzogadzirisa dambudziko iri.Sezvo nyika dzepasirese dziri kubhadhara zvakanyanya uye zvakanyanya kuchengetedza kuchengetedzwa kwezvakatipoteredza, nguva yakatarwa yekurambidzwa kwakazara kwekushandiswa kweorganotin antifouling agents yave nguva yakatarwa.Kuvandudzwa kwezvitsva uye zvinobudirira zvekudzivirira uye kushandiswa kwe nano-level antifouling agents kwakava chinhu chinonyanya kukosha kune vatsvakurudzi vependi yegungwa munyika dzakasiyana-siyana.

 1) Titanium yakatevedzana nano anticorrosive coating

 a) Nano zvinhu zvakadainano titanium dioxideuyenano zinc oxideinoshandiswa mu titanium nano anticorrosive coatings inogona kushandiswa se antibacterial agents iyo isiri-chepfu kumuviri wemunhu, ine yakakura antibacterial renji, uye ine yakanakisa kupisa kugadzikana.Zvisiri zvesimbi uye machira anoshandiswa mumakamuri engarava anowanzo kuoneswa hunyoro uye nzvimbo diki munzvimbo inosvibiswa zviri nyore, kunyanya munzvimbo dzinopisa uye dzinopisa dzemugungwa, uye dzinonyanya kukurumidza kukura nekusvibiswa.Iyo antibacterial mhedzisiro yenanomaterials inogona kushandiswa kugadzirira nyowani uye inoshanda antibacterial uye antifungal zvinhu uye machira mucabin.

 b) Nano titanium poda senge inorganic filler inogona kuvandudza ma mechanic properties uye corrosion resistance ye epoxy resin.Iyo nano-titanium poda yakashandiswa mukuyedza ine saizi isingasviki 100nm.Mhedzisiro yemhedzisiro inoratidza kuti corrosion resistance ye epoxy-modified nano-titanium powder coating uye polyamide-modified nano-titanium powder coating yakagadziridzwa ne1-2 Magnitude.Gadzirisa iyo epoxy resin shanduko uye kuparadzira maitiro.Wedzera 1% yakagadziridzwa nano titanium poda kune epoxy resin kuti uwane yakagadziridzwa nano titanium poda coating.Migumisiro yeEIS yekuedza inoratidza kuti impedance modulus ye-low-frequency end of coating inoramba iri pa 10-9Ω.cm ~ 2 mushure mekunyudzwa kwe1200h.Iyo 3 maodha ehukuru hwepamusoro kupfuura epoxy varnish.

 2) Nano zinc oxide

 Nano-ZnO chinhu chine akasiyana emhando yepamusoro zvivakwa uye yakashandiswa zvakanyanya muminda yakawanda.Iyo ine yakanakisa antibacterial properties kurwisa mabhakitiriya.Iyo titanate coupling agent HW201 inogona kushandiswa kugadzirisa pamusoro pe nano-ZnO.Iwo akagadziridzwa nano-zvinhu anoshandiswa semafirita muepoxy resin coating system kugadzirira matatu marudzi e nano-marine antifouling coatings ane bactericidal effect.Kuburikidza nekutsvagisa, zvinoonekwa kuti dispersibility yeakagadziridzwa nano-ZnO, CNT uye graphene yakavandudzwa zvakanyanya.

 3) Carbon-based nanomaterials

      Carbon nanotubes (CNT)uye graphene, seyakasimukira kabhoni-yakavakirwa zvinhu, ine zvivakwa zvakanakisa, haina chepfu, uye haisvibise nharaunda.Zvose CNT negraphene zvine bactericidal properties, uye CNT inogonawo kuderedza simba repamusoro rekuvhara.Shandisa silane coupling agent KH602 kugadzirisa pamusoro peCNT uye graphene kuti ivandudze kugadzikana kwavo uye dispersibility muhutano hwekuputira.Iwo akagadziridzwa nano-zvinhu akashandiswa semafirita kuti abatanidzwe muepoxy resin coating system kugadzirira marudzi matatu e nano-marine antifouling coatings ane bactericidal effect.Kuburikidza nekutsvagisa, zvinoonekwa kuti dispersibility yeakagadziridzwa nano-ZnO, CNT uye graphene yakavandudzwa zvakanyanya.

4) Anticorrosive uye antibacterial goko core nanomaterials

Kushandisa iyo super antibacterial zvimiro zvesirivheri uye iyo porous shell chimiro chesilica, dhizaini uye kusangana kweiyo core-shell yakarongeka nano Ag-SiO2;tsvagiridzo pahwaro hweiyo bactericidal kinetics, bactericidal mechanism uye anti-corrosion performance, pakati peiyo sirivheri musimboti Iri 20nm, ukobvu hwenano-silica shell layer inenge 20-30nm, antibacterial mhedzisiro iri pachena, uye mutengo wekuita wakakwira.

 5) Nano cuprous oxide antifouling zvinhu

      Cuprous oxide CU2Ois antifouling agent ine nhoroondo refu yekushandisa.Iko kusunungurwa kwe nano-sized cuprous oxide yakagadzikana, iyo inogona kuvandudza maitiro e-antifouling ekuputira.Iyo yakanaka anti-corrosion coating yezvikepe.Dzimwe nyanzvi dzinotofanotaura kuti nano cuprous oxide inogona Kuita kurapwa kwe organic pollutants munzvimbo.
