Ukusebenza kwama-Multi walled carbon nanotubes

Ukusebenza kukagesi

I-athomu yekhabhoni ngayinye ye-sp2 hybrid ine-electron engabhanqiwe e-perpendicular ku-pi orbital yeshidi, enikeza ama-carbon nanotubes ukuhamba kahle kukagesi.Ubuningi bamanje be-carbon nanotubes bufinyelela ku-109Acm-2, okuyizikhathi eziyi-1000 ukuqhutshwa kwethusi.Ingasetshenziswa njengocingo oluncane kakhulu, uhlelo lokusebenza olujwayelekile okwamanje lusetshenziswa njenge-ejenti eqhubayo kumabhethri e-lithium-ion.Ama-semiconducting carbon nanotubes anezinhlelo zokusebenza ezibanzi emkhakheni wemishini ye-microelectronic.

Izakhiwo zemishini

I-sp2 hybrid CC σ bond ingelinye lamabhondi amakhemikhali aqine kakhulu aziwa njengamanje.Amandla okukhiqiza e-carbon nanotubes alandelana ngamakhulu e-GPa, futhi i-modulus ye-Young ilandelana nge-TPa, ephakeme kakhulu kunaleyo ye-carbon fiber nezivikelo zomzimba.Sebenzisa i-fiber nensimbi.Kulindeleke ukuthi kuthathelwe indawo i-carbon fiber njengento entsha yamandla.

Ukusebenza okushisayo

I-carbon nanotube heat conduction system ine-avareji enkulu ye-phonon indlela yamahhala, futhi i-axial thermal conductivity ingaba phezulu njenge-6600W / (m · K), okuyizikhathi ezingaphezu kwezingu-3 zempahla ene-thermal conductivity ephakeme kakhulu ekamelweni lokushisa-idayimane. , okuyindalo Impahla eyaziwa kakhulu iyinto esebenzayo yokukhipha ukushisa emishinini kagesi.

Eminyakeni yamuva nje, ucwaningo lwe-carbon nanotubes lubonise amathuba okusebenza kumadivayisi we-nanoelectronic, okungukuthi, ngokwakha amadivaysi e-electronic kanye nezintambo ezisekelwe ku-carbon nanotubes ezinosayizi wamashumi kuphela ama-nanometers noma ngisho nangaphansi, isivinini sokuqaphela siyashesha kakhulu ukusetshenziswa kwamandla kuncane kakhulu kunesekhethi ehlanganisiwe ye-carbon nanotube yamasekethe ahlanganisiwe amanje.

Futhi i-MWCNT ye-carbon nanotubes enezindonga eziningi ingafakwa ku-conductive, anti-static, catalyst carrier, njll.
