Ukungcoliswa kwebhayoloji yasolwandle kungabangela umonakalo ezintweni zobunjiniyela basolwandle, kunciphise impilo yesevisi yezinto ezibonakalayo, futhi kubangele ukulahlekelwa okukhulu kwezomnotho kanye nezingozi eziyinhlekelele.Ukusetshenziswa kwama-anti-fouling coatings kuyisixazululo esivamile kule nkinga.Njengoba amazwe emhlabeni jikelele enaka kakhulu ukuvikelwa kwemvelo, umkhawulo wesikhathi sokuvinjelwa okuphelele kokusetshenziswa kwe-organotin antifouling ejenti isibe isikhathi esinqunyiwe.Ukuthuthukiswa kwama-antifouling agents amasha futhi asebenzayo kanye nokusetshenziswa kwe-nano-level antifouling agents kube yinto ebaluleke kakhulu kubacwaningi bepende yasolwandle emazweni ahlukahlukene.

 1) Titanium uchungechunge nano anticorrosive enamathela

 a) Izinto zeNano ezifanaI-nano titanium dioxidefuthii-nano zinc oxideesetshenziswa ku-titanium nano anticorrosive coatings ingasetshenziswa njengama-antibacterial agents angenabo ubuthi emzimbeni womuntu, anohlu olubanzi lwe-antibacterial, futhi abe nokuzinza okuhle kakhulu kokushisa.Izinto ezingezona ezensimbi nezingubo zokugqoka ezisetshenziswa ezindlini zemikhumbi zivame ukuchayeka kumswakama kanye nezikhala ezincane endaweni engcoliswa kalula, ikakhulukazi ezindaweni zasolwandle ezishisayo nezishisayo, futhi zisengozini enkulu ekukhuleni kwesikhunta kanye nokungcola.Umthelela we-antibacterial we-nanomaterials ungasetshenziswa ukulungisa izinto ezintsha nezisebenzayo ze-antibacterial kanye ne-antifungal kanye nezingubo ku-cabin.

 b) I-Nano titanium powder njengesigcwalisi esingaphili ingathuthukisa izakhiwo zemishini kanye nokumelana nokugqwala kwe-epoxy resin.I-nano-titanium powder esetshenziswe ocwaningweni inosayizi wezinhlayiyana ongaphansi kuka-100nm.Imiphumela yokuhlola ibonisa ukuthi ukumelana nokugqwala kwe-epoxy-modified nano-titanium powder coating kanye ne-polyamide-modified nano-titanium powder coating kuye kwathuthukiswa ngo-1-2 Magnitude.Lungiselela ukuguqulwa kwe-epoxy resin kanye nenqubo yokusabalalisa.Engeza i-1% eguquliwe ye-nano titanium powder ku-epoxy resin ukuze uthole i-nano titanium powder eguquliwe.Imiphumela yokuhlola ye-EIS ibonisa ukuthi i-impedance modulus yesiphetho se-low-frequency ye-coating ihlala ku-10-9Ω.cm~2 ngemva kokucwiliswa kwe-1200h.Ingama-oda angu-3 obukhulu ngaphezu kwe-epoxy varnish.

 2) Nano zinc oxide

 I-Nano-ZnO iyinto enezinto ezihlukahlukene ezinhle kakhulu futhi isetshenziswe kabanzi emikhakheni eminingi.Inezindawo ezinhle kakhulu ze-antibacterial ngokumelene namagciwane.I-ejenti yokuhlanganisa i-titanate HW201 ingasetshenziswa ukulungisa ubuso be-nano-ZnO.Izinto eziguquliwe ze-nano-materials zisetshenziswa njengezigcwalisi ohlelweni lokumboza i-epoxy resin ukuze kulungiswe izinhlobo ezintathu ze-nano-marine antifouling ene-bactericidal effect.Ngokucwaninga, kutholakala ukuthi ukuhlakazeka kwe-nano-ZnO eguquliwe, i-CNT ne-graphene kuye kwathuthukiswa kakhulu.

 3) Ama-nanomaterials asuselwa kukhabhoni

      I-Carbon nanotubes (CNT)kanye ne-graphene, njengezinto ezisafufusa ezenziwe nge-carbon, zinezakhiwo ezinhle kakhulu, azinabo ubuthi, futhi aziyingcolisi imvelo.Kokubili i-CNT ne-graphene kunezinto ezibulala amagciwane, futhi i-CNT inganciphisa namandla athile angaphezulu kwentolo.Sebenzisa i-ejenti yokuhlanganisa i-silane engu-KH602 ukuze ulungise ingaphezulu le-CNT ne-graphene ukuze uthuthukise ukuzinza nokuhlakazeka kwakho ohlelweni lokumboza.Izinto eziguquliwe ze-nano-materials zasetshenziswa njengezigcwalisi ukuze zifakwe ohlelweni lokumboza i-epoxy resin ukuze kulungiswe izinhlobo ezintathu ze-nano-marine antifouling ezinemiphumela yokubulala amagciwane.Ngokucwaninga, kutholakala ukuthi ukuhlakazeka kwe-nano-ZnO eguquliwe, i-CNT ne-graphene kuye kwathuthukiswa kakhulu.

4) Igobolondo le-Anticorrosive kanye ne-antibacterial core nanomaterials

Ukusebenzisa izakhiwo ze-antibacterial ezinkulu zesiliva kanye nesakhiwo segobolondo esinezimbotshana se-silica, ukuklama nokuhlanganisa i-nano Ag-SiO2 e-core-shell eyakhiwe;ucwaningo ngesisekelo se-bactericidal kinetics yayo, indlela ye-bactericidal kanye nokusebenza kwe-anti-corrosion, phakathi kwayo umgogodla wesiliva Ubukhulu buyi-20nm, ugqinsi lwegobolondo le-nano-silica lingaba ngu-20-30nm, umphumela we-antibacterial uyabonakala, futhi ukusebenza kwezindleko kuphezulu.

 5) Nano cuprous oxide antifouling impahla

      I-Curous oxide CU2Oiyi-ejenti evimbela ukungcola enomlando omude wokusebenzisa.Izinga lokukhishwa kwe-nano-size cuprous oxide lizinzile, elingathuthukisa ukusebenza kwe-antifouling ye-coating.Kuyi-anti-corrosion coating yemikhumbi.Abanye ochwepheshe baze babikezele ukuthi i-nano cuprous oxide ingakwazi Ukwelapha ukungcola kwemvelo emvelweni.
