Graphene e ntšoa ka har'a thepa ea graphite ea flake, kristale ea mahlakore a mabeli e entsoeng ka liathomo tsa carbon tse teteaneng athomo e le 'ngoe feela. Ka lebaka la thepa ea eona e ntle ea optical, motlakase le mechine, graphene e na le mefuta e mengata ea lits'ebetso. Kahoo na graphite ea flake le graphene lia amana? Mohlophisi oa graphite oa Furuite o latelang o sekaseka kamano pakeng tsagraphite ea lekhapetlale graphene:
1. Mokhoa oa ho ntša graphene ka bongata ha o fumanoe haholo-holo ho tsoa ho flake graphite, empa o fumanoa ho tsoa likhase tse nang le carbon tse kang methane le acetylene. Le hoja lebitso lena le na le lentsoe graphite, tlhahiso ea graphene ha e fumanoe haholo-holo ho tsoa ho flake graphite. Ho e-na le hoo, e fumanoa ho tsoa likhase tse nang le carbon tse kang methane le acetylene. Esita le mokhoa oa hona joale oa lipatlisiso o ntšoa sefateng sa limela se ntseng se hola, 'me joale ho na le mokhoa oa ho ntša graphene lifateng tsa tee.
2. Li-flakes tsa graphite li na le li-graphene tse limilione. Graphene ehlile e teng tlhahong. Haeba ho na le kamano pakeng tsa graphene le flake graphite, graphene e kenngoa lera ka lera ho etsa li-flakes tsa graphite. Graphene ke sebopeho se senyenyane haholo sa lera le le leng. Ho thoe milimithara e le 'ngoe ea flake graphite e na le li-layer tse ka bang limilione tse 3 tsa graphene, 'me botenya ba graphene bo ka bonoa. Ho sebelisa mohlala o bonahalang, mantsoe ao re a ngolang pampiring ka lipentšele a na le li-layer tse 'maloa kapa tse mashome a likete tsa graphite. ene.
Mokhoa oa ho lokisa graphene ho tsoa ho flake graphite o bonolo, o na le liphoso tse fokolang le oksijene e ngata, chai e ngata ea graphene, boholo bo itekanetseng, le litšenyehelo tse tlase, 'me o loketse tlhahiso ea indasteri e kholo.
