Carbon nanotubes (CNTS) carbon nano tubes nwere oke kpo oku na-ekpo ọkụ, na ọkụ ọkụ na-eduzi na ọnụ ụlọ dị okpukpu abụọ nke diamond. Ọ bụ ugbu a ihe kacha mma ikpo ọkụ. Ha nwere ebe kachasị nta, na nnyefe ọkụ site na mgbidi dị n'ime ya adịghị emetụta ntụpọ mgbidi ya.

Multi-wall carbon ọkpọkọ na-eji na roba, nke mere na gbanwetụrụ ụgbọ elu taya roba ihe na-enweta elu ike arụmọrụ, na-eduzi electrostatic arụmọrụ, abrasion iguzogide na thermal conductivity, na ala ike okpomọkụ.
