 1) Titanium letoto la nano anticorrosive barbotage

 a) Lisebelisoa tsa Nano tse kangnano titanium dioxidelenano zinc oxidee sebelisitsoeng ho titanium nano anticorrosive coatings e ka sebelisoa e le li-antibacterial agents tse se nang chefo 'meleng oa motho, tse nang le mefuta e mengata ea likokoana-hloko,' me li na le botsitso bo botle ba mocheso.Lisebelisoa tse se nang tšepe le liphahlo tse sebelisoang liphaposing tsa likepe li atisa ho pepesehela mongobo le libaka tse nyenyane sebakeng se silafalang habonolo, haholo-holo libakeng tsa leoatle tsa tropike le tsa tropike, 'me li kotsing haholo ke ho hōla ha hlobo le tšilafalo.Tšusumetso ea antibacterial ea li-nanomaterials e ka sebelisoa ho lokisa lisebelisoa tse ncha le tse sebetsang hantle tsa antibacterial le antifungal le likoahelo ka har'a cabin.

 b) Nano titanium phofo e le setlolo sa inorganic filler e ka ntlafatsa thepa ea mochini le ho hanyetsa kutu ea epoxy resin.Phofo ea nano-titanium e sebelisitsoeng tekong e na le boholo ba karolo e ka tlase ho 100nm.Liphetho tsa liteko li bontša hore khanyetso ea kutu ea epoxy-modified nano-titanium powder coating le polyamide-modified nano-titanium powder coating e ntlafalitsoe ke 1-2 Magnitude.Ntlafatsa phetoho ea resin ea epoxy le mokhoa oa ho hasana.Eketsa 1% e fetotsoeng phofo ea nano titanium ho epoxy resin ho fumana nano titanium phofo e fetotsoeng.Liphetho tsa liteko tsa EIS li bonts'a hore modulus ea impedance ea pheletso e tlase ea sekhahla sa ho roala e lula e le 10-9Ω.cm ~ 2 kamora ho qoelisoa ka 1200h.Ke liodara tse 3 tsa boholo bo holimo ho feta varnish ea epoxy.

 2) Nano zinc oxide

 Nano-ZnO ke thepa e nang le mefuta e mengata e metle haholo 'me e sebelisitsoe haholo mafapheng a mangata.E na le thepa e ntle ea antibacterial khahlano le libaktheria.Titanate coupling agent HW201 e ka sebelisoa ho fetola bokaholimo ba nano-ZnO.Lisebelisoa tsa nano tse fetotsoeng li sebelisoa e le li-filler ka har'a sisteme ea ho roala resin ea epoxy ho lokisa mefuta e meraro ea li-nano-marine antifouling tse nang le phello ea bactericidal.Ka lipatlisiso, ho fumanoa hore ho senyeha ha nano-ZnO, CNT le graphene e fetotsoeng ho ntlafalitsoe haholo.

 3) li-nanomaterials tse thehiloeng ho carbon

      Carbon nanotubes (CNT)'me graphene, e le lisebelisoa tse hlahang ka carbon, li na le thepa e babatsehang, ha li chefo, 'me ha li silafatse tikoloho.Ka bobeli CNT le graphene li na le thepa ea bactericidal, 'me CNT e ka boela ea fokotsa matla a khethehileng a holim'a seaparo.Sebelisa silane coupling agent KH602 ho fetola bokaholimo ba CNT le graphene ho ntlafatsa botsitso ba bona le dispersibility tsamaisong ea ho roala.Lisebelisoa tsa nano tse fetotsoeng li ile tsa sebelisoa e le li-filler tse tla kenyelletsoa ka har'a sistimi ea epoxy resin ho lokisa mefuta e meraro ea li-nano-marine antifouling tse nang le phello ea bactericidal.Ka lipatlisiso, ho fumanoa hore ho senyeha ha nano-ZnO, CNT le graphene e fetotsoeng ho ntlafalitsoe haholo.

4) Anticorrosive le antibacterial shell core core nanomaterials

Ho sebelisa thepa e matla ea antibacterial ea silevera le sebopeho sa porous shell ea silika, moralo le kopano ea core-shell e hlophisitsoeng nano Ag-SiO2;lipatlisiso motheong oa bactericidal kinetics ea eona, mokhoa oa bactericidal le ts'ebetso ea anti-corrosion, eo har'a eona mokokotlo oa silevera Ka boholo ke 20nm, botenya ba lera la khetla ea nano-silika e ka bang 20-30nm, phello ea antibacteria e hlakile, 'me ts'ebetso ea litšenyehelo e phahame.

 5) Nano cuprous oxide antifouling thepa

      Cuprous oxide CU2Oke antifouling e nang le nalane e telele ea ts'ebeliso.Sekhahla sa ho lokolloa ha nano-size cuprous oxide se tsitsitse, se ka ntlafatsang ts'ebetso ea antifouling ea ho roala.Ke seaparo se setle sa anti-corrosion bakeng sa likepe.Litsebi tse ling li bile li bolela esale pele hore nano cuprous oxide e ka Etsa kalafo ea litšila tse phelang tikolohong.
