Ngakhale kuti graphene nthawi zambiri imatchedwa "panacea", sizokayikitsa kuti ili ndi mawonekedwe owoneka bwino, magetsi ndi makina, ndichifukwa chake makampaniwa ali ofunitsitsa kumwaza graphene ngati nanofiller mu ma polima kapena matrice osakhazikika.Ngakhale ilibe zotsatira zodziwika bwino za "kusandutsa mwala kukhala golide", imathanso kupititsa patsogolo magwiridwe antchito a matrix mkati mwamitundu ina ndikukulitsa mawonekedwe ake.

Pakali pano, wamba graphene gulu zipangizo akhoza makamaka kugawidwa mu polima ofotokoza ndi ceramic-based.Pali maphunziro ochulukirapo pazakale.

Epoxy resin (EP), monga matrix omwe amagwiritsidwa ntchito nthawi zambiri, imakhala ndi zomatira bwino, mphamvu zamakina, kukana kutentha ndi mphamvu ya dielectric, koma imakhala ndi magulu ambiri a epoxy pambuyo pochiritsa, ndipo kachulukidwe kake kamakhala kokwera kwambiri, kotero zomwe zapezedwa. mankhwala ndi Chimaona ndipo alibe mphamvu kukana, magetsi ndi matenthedwe madutsidwe.Graphene ndiye chinthu chovuta kwambiri padziko lonse lapansi ndipo chimakhala ndi mphamvu yabwino kwambiri yamagetsi ndi matenthedwe.Chifukwa chake, zinthu zophatikizika zomwe zimapangidwa pophatikiza graphene ndi EP zili ndi zabwino zonse ndipo zimakhala ndi phindu logwiritsa ntchito.

     Nano Grapheneili ndi malo akuluakulu, ndipo kubalalitsidwa kwa maselo a graphene kumatha kupanga mawonekedwe amphamvu ndi polima.Magulu ogwira ntchito monga magulu a hydroxyl ndi njira yopangira adzasintha graphene kukhala makwinya.Zolakwika za nanoscale izi zimakulitsa kugwirizana pakati pa maunyolo a graphene ndi polima.Pamwamba pa functionalized graphene lili hydroxyl, carboxyl ndi magulu ena mankhwala, amene akhoza kupanga zomangira wamphamvu haidrojeni ndi ma polima polar monga polymethyl methacrylate.Graphene ili ndi mawonekedwe apadera amitundu iwiri komanso zinthu zambiri zabwino kwambiri, ndipo ili ndi kuthekera kwakukulu kogwiritsa ntchito pakuwongolera matenthedwe, maginito amagetsi ndi makina a EP.

1. Graphene mu epoxy resins - kupititsa patsogolo mphamvu zamagetsi

Graphene ili ndi madulidwe abwino kwambiri amagetsi komanso ma elekitiromaginito, ndipo ili ndi mawonekedwe a mlingo wocheperako komanso kuchita bwino kwambiri.Ndiwothandizira kusintha kwa epoxy resin EP.Ofufuzawo adayambitsa GO mu EP yokhala ndi mankhwala opangidwa ndi in-situ thermal polymerization.Makhalidwe azinthu zofananira zamagulu a GO / EP (monga makina, magetsi ndi matenthedwe, ndi zina zotero) adasinthidwa kwambiri, ndipo magetsi a magetsi anawonjezeka ndi 6.5 dongosolo la magnitude.

Kusinthidwa graphene akuphatikizana ndi epoxy utomoni, kuwonjezera 2% ya kusinthidwa graphene, modulus yosungirako epoxy gulu zinthu kumawonjezeka ndi 113%, kuwonjezera 4%, mphamvu ukuwonjezeka ndi 38%.Kukana kwa EP resin koyera ndi 10 ^ 17 ohm.cm, ndipo kukana kumatsika ndi ma 6.5 magnitude pambuyo powonjezera graphene oxide.

2. Kugwiritsa ntchito graphene mu epoxy resin - matenthedwe matenthedwe

Kuwonjezerampweya nanotubes(CNTs)ndi graphene kuti epoxy utomoni, powonjezera 20 % CNTs ndi 20% GNPs, matenthedwe madutsidwe wa zinthu gulu akhoza kufika 7.3W/mK.

3. Kugwiritsa ntchito graphene mu epoxy utomoni - retardancy lawi

Powonjezera 5 wt% organic functionalized graphene okusayidi, mphamvu yamoto retardant inawonjezeka ndi 23.7%, ndipo powonjezera 5 wt%, inawonjezeka ndi 43.9%.

Graphene ali ndi mawonekedwe a kuuma kwambiri, kukhazikika kwa mawonekedwe komanso kulimba.Monga chosinthira cha epoxy resin EP, chimatha kusintha kwambiri makina azinthu zophatikizika, ndikugonjetsa kuchuluka kwa zodzaza wamba wamba komanso kusinthasintha kocheperako ndi zolakwika zina.Ofufuzawo adagwiritsa ntchito ma nanocomposites osinthidwa ndi GO/EP.Pamene w(GO) = 0.0375%, mphamvu yopondereza ndi kulimba kwa zophatikizira zofananira zidakwera ndi 48.3% ndi 1185.2% motsatana.Asayansi anaphunzira kusintha kwa kusintha kwa kukana kutopa ndi kulimba kwa dongosolo la GO / EP: pamene w (GO) = 0.1%, modulus yamagetsi yamagulu inakula pafupifupi 12%;pamene w (GO) = 1.0%, Kulimba kwa flexural ndi mphamvu zamagulu zinawonjezeka ndi 12% ndi 23%, motero.
