ʻO nā nanotubes kalapona pā hoʻokahi (SWCNT a i ʻole SWNT) i haku ʻia me nā ʻātoma kalapona.Hiki ke manaʻo ʻia ke ʻano geometric ma ke ʻano he papa hoʻokahi o ka graphene curled, a ʻo ke ʻano e hoʻoholo i nā waiwai.No laila, loaʻa nā nanotubes kalapona paʻa hoʻokahi i nā pono uila, mechanical, a me nā mea hana.Ka hana, hoʻokahi-paia kalapona nanotubes no hoi kemika paʻa.

Hiki ke hoʻohana ʻia nā paipu kalapona pā hoʻokahi no nā capacitors nui nui.

Hoʻoholo ʻia ka nui o ka ikehu i mālama ʻia i loko o ka capacitor papa pālua uila e ka ʻāpana kiko kūpono o nā papa electrode o ka capacitor.No ka mea, ʻo nā nanotubes kalapona paʻa hoʻokahi ka ʻāpana kikoʻī nui loa a me ka conductivity maikaʻi, hiki i ka electrode i hoʻomākaukau ʻia e nā nanotubes carbon hiki ke hoʻonui nui i ka capacitance o ka capacitor papalua uila.

Wahi a nā hiʻohiʻona o nā nanotubes kalapona, loaʻa iā ia ka adsorption nui i nā wai a me nā kinoea.Mālama ʻo Carbon nanotubes i ka hydrogen ma o ka hoʻohana ʻana i nā hiʻohiʻona o ka adsorption kino a i ʻole adsorption kemika o ka hydrogen i loko o nā mea me kahi ākea ākea nui a me ka hoʻolālā pore.
