Graphene ke kristale e mahlakore a mabeli e entsoeng ka liathomo tsa khabone e le 'ngoe feela e botenya, e tlositsoeng ho thepa ea graphite ea flake. Graphene e na le mefuta e mengata ea lisebelisoa ka lebaka la thepa ea eona e babatsehang ho optics, motlakase le mechine. Joale na ho na le kamano pakeng tsa flake graphite le graphene? Letoto le latelang le lenyane la Tlhahlobo ea kamano lipakeng tsa flake graphite le graphene:
Flake graphite
1. Mokhoa oa ho ntšoa bakeng sa tlhahiso ea boima ba graphene ha e fumanehe haholo-holo ho flake graphite, empa ho tloha likhase tse nang le carbon tse kang methane le acetylene. Ho sa tsotellehe lebitso lena, tlhahiso ea graphene ha e tsoe haholo-holo ho flake graphite. E entsoe ka likhase tse nang le carbon tse kang methane le acetylene, 'me le hona joale ho na le litsela tsa ho ntša graphene limela tse ntseng li hōla, 'me hona joale ho na le litsela tsa ho ntša graphene lifateng tsa tee.
2. Flake graphite e na le limilione tsa graphene. Graphene e hlile e teng ka tlhaho, haeba kamano pakeng tsa graphene le flake graphite, joale graphene layer by layer ke flake graphite, graphene ke sebopeho se senyenyane haholo sa monolayer. Ho boleloa hore millimeter e le ’ngoe ea flake graphite e na le matlalo a ka bang limilione tse tharo a graphene, ’me botle ba graphene bo ka bonoa, ha ho sebelisoa mohlala o hlakileng, ha re ngola mantsoe pampiring ka pentšele, ho na le matlalo a ’maloa kapa a likete tse mashome. ea graphene.
Mokhoa oa ho lokisetsa graphene ho tloha flake graphite o bonolo, o nang le bokooa bo fokolang le oksijene, lihlahisoa tse ngata tsa graphene, boholo bo itekanetseng, le theko e tlaase, e loketseng tlhahiso e kholo ea indasteri.
