Pepa keleawe no Graphene

Kiʻi i hōʻike ʻia no ka pepa kini keleawe no Graphene

Wehewehe Pōkole:

He mea hou ka Graphene kahi i hoʻopili paʻa ʻia ai nā ʻātoma kalapona i hoʻopili ʻia e ka sp² hybridization i loko o kahi papa hoʻokahi o ka ʻōnaehana honeycomb lattice ʻelua-dimensional. Me nā waiwai optical, uila, a me mechanical maikaʻi loa, paʻa ka graphene i ka ʻōlelo hoʻohiki koʻikoʻi no nā noi ma ka ʻepekema mea, ka hana micro a me ka nano, ka ikehu, ka biomedicine, a me ka lawe ʻana i nā lāʻau lapaʻau, a ua manaʻo ʻia he mea kipi o ka wā e hiki mai ana.

He mea hou ka Graphene kahi i hoʻopaʻa paʻa ʻia ai nā ʻātoma kalapona i hoʻopili ʻia e ka sp² hybridization i loko o kahi papa hoʻokahi o ka hoʻolālā honeycomb lattice ʻelua-dimensional. Me nā waiwai optical, uila, a me mechanical maikaʻi loa, paʻa ka graphene i ka hoʻohiki koʻikoʻi no nā noi ma ka ʻepekema mea, ka hana micro a me ka nano, ka ikehu, ka biomedicine, a me ka lawe ʻana i nā lāʻau lapaʻau, a ua manaʻo ʻia he mea kipi o ka wā e hiki mai ana. ʻO ka Chemical vapor deposition (CVD) kekahi o nā ʻano hana i hoʻohana pinepine ʻia no ka hana ʻana i kāohi ʻia o ka graphene nui. ʻO kāna kumu nui ka loaʻa ʻana o ka graphene ma ke kau ʻana ma luna o ka ʻili o kahi metala ma ke ʻano he substrate a me ka catalyst, a me ka hoʻouna ʻana i kahi nui o ke kumu kalapona mua a me ke kinoea hydrogen i loko o kahi mahana kiʻekiʻe, e launa pū ana me kekahi. ʻO ka foil keleawe no ka graphene i hana ʻia e CIVEN METAL he mau ʻano o ka maʻemaʻe kiʻekiʻe, ke kūpaʻa maikaʻi, ka wafer like a me ka ʻili pālahalaha, he mea substrate kūpono ia i ke kaʻina hana CVD.
