Nubwo graphene bakunze kwita "panacea", ntawahakana ko ifite ibintu byiza bya optique, amashanyarazi nubukanishi, niyo mpamvu inganda zishishikajwe no gukwirakwiza graphene nka nanofiller muri polymers cyangwa matricique.Nubwo idafite ingaruka zamugani zo "guhindura ibuye zahabu", irashobora kandi kunoza igice cyimikorere ya matrix murwego runaka no kwagura ibikorwa byayo.

Kugeza ubu, ibikoresho rusange bya graphene bishobora kugabanywa cyane cyane bishingiye kuri polymer na ceramic.Hariho ubushakashatsi bwinshi kubwa mbere.

Epoxy resin (EP), nkibisanzwe bikoreshwa muri resin matrix, ifite ibintu byiza cyane byo gufatira hamwe, imbaraga za mashini, kurwanya ubushyuhe hamwe na dielectric, ariko irimo umubare munini wamatsinda ya epoxy nyuma yo gukira, kandi ubucucike bwambukiranya ni bwinshi cyane, kubwibyo wabonye ibicuruzwa biroroshye kandi bifite ingaruka mbi zo kurwanya, amashanyarazi nubushyuhe bwumuriro.Graphene nikintu gikomeye cyane kwisi kandi gifite amashanyarazi meza nubushyuhe.Kubwibyo, ibikoresho byose byakozwe muguhuza graphene na EP bifite ibyiza byombi kandi bifite agaciro keza.

     Nano Grapheneifite ubuso bunini, kandi molekulari-urwego rwo gukwirakwiza graphene irashobora gukora intera ikomeye hamwe na polymer.Amatsinda akora nka hydroxyl matsinda hamwe nuburyo bwo kubyara bizahindura graphene muburyo bwuzuye.Ibi bidasanzwe bya nanoscale byongera imikoranire hagati ya graphene na polymer.Ubuso bwa graphene ikora burimo hydroxyl, carboxyl nandi matsinda yimiti, ashobora gukora hydrogène ikomeye hamwe na polymer polymers nka polymethyl methacrylate.Graphene ifite imiterere yihariye yuburyo bubiri nuburyo bwinshi buhebuje, kandi ifite imbaraga zo gukoresha mugutezimbere ubushyuhe, amashanyarazi na mashini ya EP.

1. Graphene muri epoxy resin - kunoza imiterere ya electromagnetic

Graphene ifite amashanyarazi meza cyane hamwe na electromagnetic, kandi ifite ibiranga dosiye nkeya kandi ikora neza.Nibishobora guhindura imikorere ya epoxy resin EP.Abashakashatsi berekanye GO-ivurwa hejuru muri EP muburyo bwa polymerisiyasi.Imiterere yuzuye yibigize GO / EP ihuye (nkibikoresho bya mashini, amashanyarazi nubushyuhe, nibindi) byatejwe imbere kuburyo bugaragara, kandi amashanyarazi yiyongereyeho 6.5 yubunini.

Graphene yahinduwe yongewemo na epoxy resin, yongeraho 2% ya graphene yahinduwe, modulus yo kubika ibintu bya epoxy compte material yiyongera kuri 113%, yongeraho 4%, imbaraga ziyongera 38%.Kurwanya EP isukuye ni 10 ^ 17 ohm.cm, kandi kurwanya bigabanukaho 6.5 byubunini nyuma yo kongeramo okiside ya graphene.

2. Gukoresha graphene muri epoxy resin - ubushyuhe bwumuriro

Ongerahocarbone nanotubes (CNTs)na graphene kuri epoxy resin, mugihe wongeyeho 20% CNT na 20% GNPs, ubushyuhe bwumuriro wibikoresho bishobora kugera kuri 7.3W / mK.

3. Gukoresha graphene muri epoxy resin - flame retardancy

Iyo wongeyeho 5 wt% organic organique ikora graphene oxyde, agaciro ka flame retardant yiyongereyeho 23.7%, kandi iyo wongeyeho 5 wt%, wiyongereyeho 43.9%.

Graphene ifite ibiranga ubukana buhebuje, guhagarara neza no gukomera.Nkuguhindura epoxy resin EP, irashobora kunoza cyane imiterere yubukanishi bwibikoresho, kandi ikanesha umubare munini wibisanzwe byuzuzanya hamwe nubushobozi buke bwo guhindura nibindi bitagenda neza.Abashakashatsi bakoresheje imiti ya GO / EP nanocomposite.Iyo w (GO) = 0.0375%, imbaraga zo kwikomeretsa hamwe nubukomere bwibigize bihuye byiyongereyeho 48.3% na 1185.2%.Abahanga bakoze ubushakashatsi ku ngaruka zo guhindura umunaniro no gukomera kwa sisitemu ya GO / EP: iyo w (GO) = 0.1%, modulus ya tensile ya compte yiyongereyeho hafi 12%;iyo w (GO) = 1.0%, Gukomera no gukomera kwimbaraga byiyongereyeho 12% na 23%.
