Nakuba i-graphene ivame ukubizwa ngokuthi “i-panacea”, akunakuphikwa ukuthi inezinto ezinhle kakhulu zokubona, zikagesi nezomshini, yingakho imboni izimisele kakhulu ukuhlakaza i-graphene njenge-nanofiller kuma-polymers noma ku-matrice we-inorganic.Nakuba ingenawo umthelela oyinganekwane "wokuguqula itshe libe igolide", ingaphinda ithuthukise ingxenye yokusebenza kwe-matrix phakathi kwebanga elithile futhi inwebise ububanzi bayo bokusebenza.

Njengamanje, izinto ezijwayelekile ezihlanganisiwe ze-graphene zingahlukaniswa ngokuyinhloko zibe yi-polymer-based and ceramic-based.Ziningi izifundo zangaphambili.

I-Epoxy resin (EP), njenge-resin matrix evame ukusetshenziswa, inezici ezinhle kakhulu zokunamathela, amandla okusebenza, ukumelana nokushisa kanye nezindawo ze-dielectric, kodwa iqukethe inani elikhulu lamaqembu e-epoxy ngemva kokwelashwa, futhi ukuminyana okuxhumanisa kuphezulu kakhulu, ngakho-ke okutholiwe imikhiqizo i-brittle futhi inokumelana nomthelela omubi, ukuqhutshwa kukagesi nokushisayo.I-graphene iyinto enzima kunazo zonke emhlabeni futhi inokushintshwa okuhle kakhulu kukagesi nokushisayo.Ngakho-ke, izinto eziyinhlanganisela ezenziwe ngokuhlanganisa i-graphene ne-EP zinezinzuzo zakho kokubili futhi zinenani elihle lesicelo.

     I-Nano Grapheneinendawo enkulu, futhi ukuhlakazeka kwezinga lamangqamuzana egraphene kungakha ukuxhumana okuqinile ne-polymer.Amaqembu asebenzayo afana namaqembu e-hydroxyl kanye nenqubo yokukhiqiza izoguqula i-graphene ibe yisimo esishwabene.Lokhu kungahambi kahle kwe-nanoscale kuthuthukisa ukusebenzisana phakathi kwamaketanga e-graphene ne-polymer.Ingaphezulu le-graphene elisebenza ngokusebenza liqukethe i-hydroxyl, i-carboxyl namanye amaqembu amakhemikhali, angakha amabhondi e-hydrogen aqinile nama-polymer amhlophe njenge-polymethyl methacrylate.I-graphene inesakhiwo esiyingqayizivele esinezinhlangothi ezimbili kanye nezakhiwo eziningi ezinhle kakhulu, futhi inamandla amakhulu wokusebenzisa ekuthuthukiseni izakhiwo ezishisayo, zikazibuthe zikagesi kanye nemishini ye-EP.

1. I-Graphene kuma-epoxy resins - ukuthuthukisa izakhiwo ze-electromagnetic

I-graphene ine-conductivity kagesi enhle kakhulu kanye nezakhiwo zikagesi, futhi inezici zomthamo ophansi nokusebenza kahle okuphezulu.Kuyi-conductive modifier engaba khona ye-epoxy resin EP.Abacwaningi bethule i-GO ephathwa phezulu ku-EP nge-in-situ thermal polymerization.Izici eziphelele zezinhlanganisela ze-GO/EP ezihambisanayo (ezifana nemishini, ugesi kanye nezindawo ezishisayo, njll.) zathuthukiswa kakhulu, futhi ukuqhutshwa kukagesi kwandiswa ngo-6.5 oda lobukhulu.

I-graphene eguquliwe ihlanganiswe ne-epoxy resin, yengeza u-2% we-graphene eguquliwe, i-modulus yokugcina impahla ye-epoxy composite inyuka ngo-113%, yengeza u-4%, amandla akhuphuka ngo-38%.Ukumelana ne-resin ye-EP ehlanzekile ngu-10 ^ 17 ohm.cm, futhi ukumelana kwehla ngama-oda angu-6.5 wobukhulu ngemva kokwengeza i-graphene oxide.

2. Ukusetshenziswa kwe-graphene ku-epoxy resin - conductivity eshisayo

Ukungezaama-carbon nanotubes(CNTs)kanye ne-graphene ku-epoxy resin, lapho wengeza u-20 % CNTs kanye no-20% GNPs, ukuqhutshwa kokushisa kwezinto ezihlanganisiwe kungafinyelela ku-7.3W/mK.

3. Ukusetshenziswa kwe-graphene ku-epoxy resin - ukubuyiswa komlilo

Lapho wengeza i-5 wt% ye-organic functionalized graphene oxide, inani le-flame retardant lenyuke ngo-23.7%, futhi lapho wengeza u-5 wt%, lenyuke ngo-43.9%.

I-graphene inezici zokuqina okuhle kakhulu, ukuzinza kwe-dimensional kanye nokuqina.Njengesiguquli se-epoxy resin EP, singathuthukisa kakhulu izakhiwo zemishini yezinto eziyinhlanganisela, futhi sinqobe inani elikhulu lezigcwalisi ezingaphili ezijwayelekile kanye nokusebenza kahle kokulungiswa okuphansi nokunye ukushiyeka.Abacwaningi basebenzise ama-nanocomposites e-GO/EP ashintshwe ngamakhemikhali.Lapho i-w(GO)=0.0375%, amandla okucindezela kanye nokuqina kwezinhlanganisela ezihambisanayo kukhuphuke ngo-48.3% no-1185.2% ngokulandelanayo.Ososayensi bafunde umphumela wokuguqulwa wokumelana nokukhathala kanye nokuqina kwesistimu ye-GO/EP: lapho w(GO) = 0.1%, i-tensile modulus yenhlanganisela yanda cishe nge-12%;lapho i-w(GO) = i-1.0%, Ukuqina kwe-flexural namandla enhlanganisela kwanda ngo-12% no-23%, ngokulandelana.
