ʻOiai ua kapa pinepine ʻia ʻo graphene ʻo "ka panacea", ʻaʻole hiki ke hōʻole ʻia he maikaʻi kona ʻano optical, uila a me ka mechanical, ʻo ia ke kumu i makemake nui ai ka ʻoihana e hoʻopuehu i ka graphene ma ke ʻano he nanofiller i nā polymers a i ʻole matrice inorganic.ʻOiai ʻaʻole i loaʻa ka hopena koʻikoʻi o ka "hoʻololi ʻana i ka pōhaku i gula", hiki iā ia ke hoʻomaikaʻi i kahi ʻāpana o ka hana o ka matrix i loko o kahi ākea a hoʻonui i kāna ʻano noi.

I kēia manawa, hiki ke hoʻokaʻawale ʻia nā mea hana graphene maʻamau i ka polymer-based a me ka ceramic-based.Nui aʻe nā haʻawina e pili ana i ka mua.

ʻO ka epoxy resin (EP), ma ke ʻano he resin matrix maʻamau, loaʻa nā waiwai adhesion maikaʻi loa, ikaika mechanical, pale wela a me nā waiwai dielectric, akā aia ka nui o nā hui epoxy ma hope o ka hoʻōla ʻana, a ʻoi aku ka kiʻekiʻe o ka crosslinking density. palupalu nā huahana a loaʻa ʻole ka hopena maikaʻi ʻole, ka uila a me ka thermal conductivity.ʻO Graphene ka mea paʻakikī loa ma ka honua a he maikaʻi ka uila a me ka wela.No laila, ʻo ka mea hoʻohuihui i hana ʻia e ka hui ʻana i ka graphene a me ka EP loaʻa nā mea maikaʻi o nā mea ʻelua a he waiwai hoʻohana maikaʻi.

     Nano GrapheneHe ʻāpana ili nui kona, a hiki i ka hoʻopuehu ʻana o ka molecular-level o graphene ke hana i kahi pilina ikaika me ka polymer.ʻO nā hui hana e like me nā pūʻulu hydroxyl a me ke kaʻina hana e hoʻohuli i ka graphene i kahi kūlana wrinkled.Hoʻonui kēia mau mea ʻole nanoscale i ka pilina ma waena o nā kaulahao graphene a me nā polymer.Aia ka ili o ka graphene i hana ʻia he hydroxyl, carboxyl a me nā hui kemika ʻē aʻe, hiki ke hana i nā paʻa hydrogen ikaika me nā polymers polar e like me ka polymethyl methacrylate.Loaʻa i ka Graphene kahi hanana ʻelua-dimensional kūʻokoʻa a me nā waiwai maikaʻi loa he nui, a loaʻa iā ia ka mana hoʻohana nui i ka hoʻomaikaʻi ʻana i nā mea wela, electromagnetic a me nā ʻano mechanical o EP.

1. Graphene i loko o ka epoxy resins - hoʻomaikaʻi i nā waiwai electromagnetic

Loaʻa iā Graphene ka conductivity uila maikaʻi loa a me nā waiwai electromagnetic, a loaʻa iā ia nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa a me ka hana kiʻekiʻe.He mea hoʻololi conductive kūpono no ka epoxy resin EP.Ua hoʻolauna nā mea noiʻi iā GO i mālama ʻia i ka ʻili i EP e ka polymerization thermal in-situ.Ua hoʻomaikaʻi maikaʻi ʻia nā waiwai holoʻokoʻa o nā hui GO / EP e pili ana (e like me ka mechanical, electrical and thermal properties, etc.) a ua hoʻonui ʻia ka conductivity uila e 6.5 kauoha o ka nui.

Hoʻohui ʻia ka graphene i hoʻololi ʻia me ka resin epoxy, hoʻohui i ka 2% o ka graphene i hoʻololi ʻia, piʻi ka modulus mālama o nā mea hoʻohui epoxy e 113%, hoʻohui 4%, piʻi ka ikaika e 38%.ʻO ke kū'ē o ka resin EP maʻemaʻe he 10^17 ohm.cm, a hāʻule ke kū'ē i ka 6.5 kauoha o ka nui ma hope o ka hoʻohui ʻana i ka graphene oxide.

2. Hoʻohana i ka graphene i ka epoxy resin - thermal conductivity

Hoʻohuinā nanotubes kalapona(CNTs)a me ka graphene i ka epoxy resin, i ka hoʻohui ʻana i 20 % CNTs a me 20% GNPs, hiki i ka conductivity thermal o ka mea hoʻohuihui ke hiki i 7.3W/mK.

3. Ka hoʻohana ʻana i ka graphene i loko o ka epoxy resin - hoʻopaneʻe ahi

I ka hoʻohui ʻana i 5 wt% organic functionalized graphene oxide, ua hoʻonui ʻia ka waiwai hoʻopaʻa ahi e 23.7%, a i ka hoʻohui ʻana i 5 wt%, ua hoʻonui ʻia e 43.9%.
