Yize i-graphene evame ukuba khona "i-panacea", ayinakuphikwa ukuthi inezakhiwo ezinhle kakhulu zokukhanya, zikagesi nezemishini, yingakho imboni ifisa ukuhlakazeka i-graphene njenge-nanofiller kuma-palmers noma i-inorganic matrice. Yize ingenawo umphumela odumile 'wokuguqula itshe libe yigolide ", futhi lingathuthukisa nengxenye yokusebenza kwe-matrix ngaphakathi kwebanga elithile futhi wandise uhla lwalo lwesicelo.

Njengamanje, izinto ezijwayelekile ze-graphene composite zingahlukaniswa ikakhulu zihlukaniswe nge-polymer-based ne-ceramic-based. Kunezifundo eziningi zangaphambili.

I-Epoxy Resin (EP), njenge-Resin Matrix esetshenziswa kakhulu, inezakhiwo ezinhle kakhulu zokunamathela, amandla okushisa kanye nezakhiwo ezinkulu ze-epoxy ngemuva kokuphulukisa, ngakho-ke imikhiqizo etholwayo iphakeme kakhulu, ngakho-ke imikhiqizo etholwayo iphakeme kakhulu, ngakho-ke imikhiqizo etholwayo iphakeme futhi inokuphikiswa komthelela ongemuhle, ugesi nowokuphamba okushisayo. I-Graphene yinto enzima kunazo zonke emhlabeni futhi inokuphakelayo okukagesi okuthe xaxa nokwenziwa okushisayo. Ngakho-ke, impahla eyinhlanganisela eyenziwe ngokuhlanganisa i-graphene kanye no-EP inezinzuzo zombili futhi inenani elihle lesicelo.

     I-nano grapheneInendawo enkulu engaphezulu, kanye nokuhlakazwa kwezinga le-molecular of graphene kungakha isikhombimsebenzisi esinamandla nge-polymer. Amaqembu asebenzayo anjengamaqembu e-hydroxylos kanye nenqubo yokukhiqiza azoshintsha i-graphene ibe yisimo esibiwe. Lezi zinto ezingekho emthethweni ze-nanoscale zithuthukisa ukuxhumana phakathi kwamaketanga we-graphene kanye ne-polymer. Ingaphezulu le-graphe enenhlekelele liqukethe i-hydroxyl, i-carboxyl namanye amaqembu amakhemikhali, angakha amabhondi aqinile we-hydrogen ngama-polmethyl methacrylate. I-Graphene inesakhiwo esiyingqayizivele esinezinhlangothi ezimbili kanye nezakhiwo eziningi ezinhle kakhulu, futhi inekhono elihle kakhulu lokusebenza ekuthuthukiseni i-thermal, electromagnetic and mehendi ep.

1. I-Graphene e-Epoxy Resins - Ukwenza ngcono izakhiwo ze-electromagnetic

I-Graphene inobuhlakani obuhle kagesi kanye nezakhiwo ze-electromagnetic, futhi inezici zemithamo ephansi kanye nokusebenza kahle. Kuyinto engahle yenzelwe ukuvumelanisa kwe-epoxy resin ep. Abaphenyi baletha ekwelapheni okungaphezulu kwe-EP nge-In-Situ Thermal Polymerization. Izakhiwo ezibanzi zezinhlanganisela ezihambisanayo ze-GO / EP (njengemishini, kagesi kanye nezakhiwo ezishisayo, njll.) Zathuthukiswa kakhulu, futhi ukuthuthuka kukagesi kwandiswa ngokulandelana kuka-6.5 ngobukhulu.

I-GROPHFEDIED ​​eguquliwe ihlanganiswe ne-epoxy resin, engeza i-2% ye-graphene eguquliwe, i-modululus yesitoreji ye-epoxy composite impahla inyuswa ngo-113%, engeza ama-4%, amandla anda ngama-38%. Ukumelana kwe-EP Resin emsulwa kuyi-10 ^ 17 OHM.CM, kanye nokumelana kwehla ngama-oda ayi-6.5 wobukhulu ngemuva kokufaka i-grafgene oxide.

2. Ukusetshenziswa kwe-Graphene e-Epoxy Resin - Ukuvuselelwa kwe-Thermal

OkufanelezelaI-Carbon Nanotubes (CNTs)Futhi i-graphe e-epoxy resin, lapho ungeza ama-20% CNTs nama-20% GNPs, ukuthuthuka okushisayo kwezinto ezihlanganisiwe kungafinyelela ku-7.3W / Mk.

I-3. Ukusetshenziswa kwe-Graphene e-Epoxy Resin - I-Flame Retardancy

Lapho ungeza i-5 wt% organic organic organic oc oxide, inani le-flame retardant lenyuke ngo-23.7%, futhi lapho ungeza i-5 wt%, enyuswe ngo-43.9%.

I-Graphene inezimpawu zobuqili obuhle kakhulu, ukuzinza kobukhulu nokuqina. Njengomshini wokushintsha we-epoxy resin ep, kungathuthukisa kakhulu izakhiwo zemishini zezinto ezihlanganisiwe, futhi unqobe inani elikhulu labadlali be-innorganic abajwayelekile kanye nokunye ukuguqulwa kahle. Abaphenyi basebenzise amakhemikhali ama-go / ep nanocomos. Lapho w (go) = 0.0375%, amandla acindezelayo kanye nobunzima bezimpawu ezihambisanayo kukhuphuke ngo-48.3% no-1185.2% ngokulandelana. Ososayensi bafunda umphumela wokuguqulwa kokulwa nokungabekezeleli nokuqina kohlelo lwe-GO / EP: Lapho W (go) = 0,1%, i-modulus tensile ye-composite inyuswe cishe ngo-12%; Lapho w (go) = 1.0%, ukuqina okuguqukayo namandla wenhlanganisela kwandiswa ngo-12% no-23%, ngokulandelana.
