Njenge-nano-material enezinhlangothi ezimbili, i-graphene inezakhiwo ezinhle kakhulu zomzimba namakhemikhali. Yi-nano-material ezacile kodwa enzima kunazo zonke etholwe abantu okwamanje. Ukuqina kwayo kuphindwe izikhathi ezingama-200 kobensimbi. Inezici ezinhle kakhulu zikagesi neze-optical, futhi ukumelana kwayo kungu-10-6_.· M, iyinto ephansi kakhulu yokumelana ne-resistivity emhlabeni okwamanje; ine-conductivity enhle yokushisa, ene-thermal conductivity engu-5300 W/(mK) ekamelweni lokushisa, futhi idlule umkhawulo we-isomorphic bulk graphite, carbon nanotubes namadayimane, okudlula kude izinto zensimbi ezifana nesiliva nethusi; inomsebenzi ophezulu othize ongaphezulu, ukusebenza kahle kwe-adsorption futhi inesibindi sokumunca umthofu ongu-800. Mg/g, ephakeme kakhulu kunekhabhoni ecushiwe.

I-graphene, njengento eguquguqukayo kakhulu "yomhlaba wonke", ingasetshenziswa ukwenza amaseli elanga, izikhali zomzimba, imishini yokubona ebusuku, njll. Muva nje, ucwaningo olwenziwa yiBrown University e-United States lubonisa ukuthi i-graphene oxide, ephuma ku-graphene, futhi inomphumela wokuxosha omiyane, lapho umhloli egcoba isikhumba ngefilimu ekhanyayo ye-graphene oxide. Ngemva kwefilimu, kwatholakala ukuthi omiyane abambalwa ababezohlala ngaphandle kwefilimu eyomile ye-graphene oxide. Ngisho noma umiyane wahlala, kungaba nzima ukungena efilimini ye-graphene oxide. Lokhu kusho ukuthi i-graphene oxide ingaba isithiyo sokuphazamisa omiyane.

Kuyaphawuleka ukuthi omiyane babeyohlonza indawo yento ehlosiwe ngokuthola ukwakheka kwamakhemikhali esikhumbeni somuntu, kodwa lapho umhloli egoqa izingubo nge-graphene oxide, omiyane abazange nje balume isikhumba esivikelwe, kodwa futhi abazange. luma isikhumba esivele

“Sasicabanga ukuthi i-graphene oxide iyisithiyo esingokomzimba esivimbela omiyane ukuba balume, kodwa lapho siqeda lokhu kuhlola, saqala ukucabanga ukuthi i-graphene oxide iphinde ibe umgoqo wamakhemikhali owawuvimbela omiyane ukuba bazizwe bephila njengomuntu,” kusho uCintia Castilho, umbhali oholayo. wocwaningo kanye nomfundi kaDkt. Brown.

UWilliam Suk we-NIEHS Superfund Research Programme Doctor uthe ulwazi oluzuzwe kulolu cwaningo lungaholela ekwakhiweni kwezingubo ezintsha zokuxosha omiyane, ukuze abantu basezindaweni ezishisayo banciphise amathuba okuba nezifo ezithathelwanayo ezibangelwa omiyane, njenge-dengue fever, I-encephalitis yaseJapane, njll., futhi iphinde inciphise inani lemikhiqizo exosha omiyane esetshenzisiwe, ngaphandle kokuphazamisa isimiso sezinzwa ngenxa yokufafaza ngokweqile.
