Kuita kweMulti walled carbon nanotubes

Kuita kwemagetsi

Imwe neimwe kabhoni atomu yesp2 hybrid ine isina kupetwa erekitironi perpendicular kune pi orbital yepepa, iyo inopa kabhoni nanotubes yakanakisa conductivity yemagetsi.Iyo yakakura ikozvino density yekabhoni nanotubes inogona kusvika 109Acm-2, inova ka1000 kanopfuura conductivity yemhangura.Inogona kushandiswa sewaya diki kwazvo, iyo yakajairika application ikozvino inoshandiswa se conductive agent mumabhatiri e lithium-ion.Iyo semiconducting kabhoni nanotubes ine yakafara application mumunda we microelectronic zvishandiso.

Mechanical properties

sp2 hybrid CC σ bond ndeimwe yeakasimba makemikari mabhondi anozivikanwa parizvino.Simba regoho rekabhoni nanotubes riri muhurongwa hwemazana eGPa, uye Yechidiki modulus iri muhurongwa hweTPa, iyo yakanyanya kukwirira kupfuura iyo kabhoni fiber uye nhumbi dzokurwa.Shandisa fiber nesimbi.Inotarisirwa kutsiva kabhoni fiber sechinhu chitsva chesimba.

Thermal performance

Iyo kabhoni nanotube heat conduction system ine yakakura avhareji phonon yemahara nzira, uye iyo axial thermal conductivity inogona kunge yakakwira se6600W / (m · K), iyo inodarika katatu zvinhu zvine yakanyanya kupisa conductivity pakamuri tembiricha-dhaimani. , iyo iri muzvisikwa Chinhu chepamusoro-soro chinozivikanwa chinhu chinoshanda chekupisa kupisa mumidziyo yemagetsi.

Mumakore achangopfuura, kutsvagurudza kwekabhoni nanotubes kwakaratidza tarisiro yekushandiswa mumidziyo yemagetsi, kureva, nekuvaka midziyo yemagetsi uye waya dzinobva pacarbon nanotubes nehukuru hwemakumi chete emakumi emamita kana kunyange idiki, kukurumidza kwekuziva kunokurumidza. mashandisirwo emagetsi idiki pane kabhoni nanotube akasanganiswa maseketi eazvino akabatanidzwa maseketi.

Zvakare MWCNT yakawanda-yakavezwa kabhoni nanotubes inogona kuiswa kune conductive, anti-static, catalyst carrier, nezvimwe.
