Ukungcoliswa kwebhayoloji yaselwandle kunokubangela umonakalo kwizinto zobunjineli baselwandle, ukunciphisa ubomi benkonzo yemathiriyeli, kwaye kubangele ilahleko enkulu yezoqoqosho kunye neengozi eziyingozi.Ukusetyenziswa kwee-anti-fouling coatings sisisombululo esiqhelekileyo kule ngxaki.Njengoko amazwe emhlabeni jikelele ehlawula ingqalelo ngakumbi nangakumbi ekukhuselweni kwendalo, umda wexesha lokuvalwa ngokupheleleyo kokusetyenziswa kwe-organotin antifouling agents ibe lixesha eliqinisekileyo.Ukuphuhliswa kwezinto ezintsha kunye nokusebenza kakuhle kwe-antifouling agents kunye nokusetyenziswa kwe-nano-level antifouling agents ziye zaba yinto ebaluleke kakhulu kubaphandi bepeyinti yolwandle kumazwe ahlukeneyo.

 1) Titanium series nano anticorrosive ukutyabeka

 a) Nano izixhobo ezifananano titanium dioxidekwayenano zinc oxideisetyenziswe kwi-titanium nano anticorrosive coatings ingasetyenziswa njenge-antibacterial agents ezingenayo ityhefu emzimbeni womntu, ezinoluhlu olubanzi lwe-antibacterial, kwaye zinozinzo oluhle kakhulu lwe-thermal.Imathiriyeli engeyiyo isinyithi kunye neengubo zokwaleka ezisetyenziswa kwiikhabhinethi zeenqanawa zihlala zisesichengeni sokufuma kunye neendawo ezincinci kwindawo engcoliseka lula, ngakumbi kwiindawo eziphantsi kwetropikhi kunye neetropikhi zaselwandle, kwaye zichaphazeleka kakhulu kukukhula kokungunda kunye nongcoliseko.Impembelelo ye-antibacterial ye-nanomaterials ingasetyenziselwa ukulungiselela izinto ezintsha kunye nokusebenza kakuhle kwe-antibacterial kunye ne-antifungal kunye neengubo kwi-cabin.

 b) I-Nano titanium powder njenge-inorganic filler inokuphucula iimpawu zoomatshini kunye nokumelana nokubola kwe-epoxy resin.I-nano-titanium powder esetyenzisiweyo kuvavanyo inobungakanani beqhekeza elingaphantsi kwe-100nm.Iziphumo zovavanyo zibonisa ukuba ukuxhathisa kwe-corrosion ye-epoxy-modified nano-titanium powder coating kunye ne-polyamide-modified nano-titanium powder coating iye yaphuculwa yi-1-2 Ubukhulu.Lungiselela ukuguqulwa kwe-epoxy resin kunye nenkqubo yokusabalalisa.Yongeza i-1% eguqulweyo ye-nano titanium powder kwi-epoxy resin ukuze ufumane i-nano titanium powder eguquliweyo.Iziphumo zovavanyo lwe-EIS zibonisa ukuba imodyuli ye-impedance ye-low-frequency end of the coating ihlala kwi-10-9Ω.cm ~ 2 emva kokucwiliswa kwe-1200h.Yimiyalelo ye-3 yobukhulu obuphezulu kune-epoxy varnish.

 2) Nano zinc oxide

 I-Nano-ZnO yimathiriyeli eneempawu ezahlukeneyo ezibalaseleyo kwaye isetyenziswe ngokubanzi kwiinkalo ezininzi.Ineempawu ezibalaseleyo zokulwa neebhaktheriya.I-agent edibanisa i-titanate HW201 ingasetyenziselwa ukuguqula umphezulu we-nano-ZnO.Izinto eziguquliweyo ze-nano-material zisetyenziswa njengezizalisi kwi-epoxy resin coating system ukulungiselela iindidi ezintathu ze-nano-marine antifouling coatings ene-bactericidal effect.Ngophando, kufunyenwe ukuba i-dispersibility ye-nano-ZnO elungisiweyo, i-CNT kunye ne-graphene iphuculwe kakhulu.

 3) I-nanomaterials esekelwe kwiCarbon

      Iinanotube zeCarbon (CNT)kunye negraphene, njengezinto ezisahlumayo ezisekwe kwikhabhoni, zineempawu ezigqwesileyo, azinatyhefu, kwaye aziyingcolisi indalo.Zombini i-CNT kunye ne-graphene zineempawu ze-bactericidal, kwaye i-CNT inokunciphisa amandla athile omgangatho wengubo.Sebenzisa i-agent yokudibanisa i-silane i-KH602 ukuguqula indawo ye-CNT kunye ne-graphene ukuphucula ukuzinza kwabo kunye ne-dispersibility kwinkqubo yokugqoka.Izinto eziguquliweyo ze-nano-material zasetyenziswa njengezizalisi ukuba zibandakanywe kwinkqubo yokugquma i-epoxy resin ukulungiselela iintlobo ezintathu ze-nano-marine antifouling coatings ene-bactericidal effect.Ngophando, kufunyenwe ukuba i-dispersibility ye-nano-ZnO elungisiweyo, i-CNT kunye ne-graphene iphuculwe kakhulu.

4) I-anticorrosive kunye ne-antibacterial shell core nanomaterials

Ukusebenzisa iimpawu ze-antibacterial eziphezulu zesilivere kunye ne-shell shell ye-silika, ukuyila kunye nendibano ye-core-shell eyakhiwe nge-nano Ag-SiO2;uphando ngesiseko se-bactericidal kinetics yayo, indlela ye-bactericidal kunye nokusebenza kwe-anti-corrosion, phakathi kwayo isiseko sesilivere Ubukhulu buyi-20nm, ubukhulu beqokobhe le-nano-silica limalunga ne-20-30nm, umphumo we-antibacterial uyabonakala, kwaye ukusebenza kweendleko kuphezulu.

 5) Nano cuprous oxide antifouling izinto

      Cuprous oxide CU2Oyi-arhente echasene ne-antifouling enembali ende yokusetyenziswa.Izinga lokukhululwa kwe-nano-size cuprous oxide lizinzile, elinokuphucula ukusebenza kwe-antifouling yengubo.Yinto entle yokugquma umhlwa kwiinqanawa.Ezinye iingcali zide ziqikelele ukuba i-nano cuprous oxide inokwenza unyango lwe-organic pollunts kwindawo engqongileyo.
