ʻO ka pauka CNTs paʻa nui
MWCNTs(CAS No. 308068-56-6) ma ke ano pauda
ʻO ka conductivity kiʻekiʻe
Hana ʻia
Pōkole-MWCNTs
Nā MWCNT lōʻihi
Loaʻa kahi ʻāpana kikoʻī nui
Kaomi ma aneʻi no nā MWCNT hana ʻole
Hoʻopuehu ʻia nā CNT i hoʻopaʻa ʻia
MWCNT ma ke ano wai.Me ka hoʻohana ʻana i nā mea hoʻopuehu kikoʻī a me ka ʻenehana hoʻopuehu i hōʻoia ʻia, ua hui pū ʻia nā cnts multi-walled, dispersing agent a me ka wai deionized a i ʻole nā mea wai ʻē aʻe e hoʻomākaukau i nā dispersion carbon nanotubes nui loa.
Hoʻopaʻa ʻia: max 5%
Hoʻopili ʻia i loko o nā ʻōmole ʻeleʻele
Ka manawa hoʻouna: ma 4 mau lā hana
Hoʻouna ʻia ma ka honua holoʻokoʻa
Nā mea mālama wai hydrogen:
Ua hōʻike ʻia nā haʻawina he kūpono loa nā nanotubes carbon e like me nā mea mālama hydrogen.
E like me ka structural hiʻona o hoʻokahi-paʻa kalapona nanotubes, i ka hopena i ka nui adsorption o ka wai a me ke kinoea.
ʻO ka mālama ʻana i ka carbon nanotube hydrogen ka hoʻohana ʻana i ka adsorption kino a i ʻole nā mea waiwai adsorption o ka hydrogen i loko o nā mea porous me kahi ākea nui e mālama i ka hydrogen ma 77-195K a ma kahi o 5.0Mpa.
ʻO nā supercapacitors mana nui:
Loaʻa i ka carbon nanotubes ka crystallinity kiʻekiʻe, ka conductivity uila maikaʻi, ka ʻāpana kikoʻī kikoʻī nui a me ka nui micropore hiki ke hoʻomalu ʻia e ka hana synthesis.Hiki i ka 100% ka nui o ka hoʻohana ʻana i ka ʻili o ka carbon nanotubes, nona nā koi āpau o nā mea electrode kūpono no nā supercapacitors.
No nā capacitors papalua, ʻike ʻia ka nui o ka ikehu i mālama ʻia e ka ʻāpana kikoʻī kūpono o ka pā electrode.No ka mea, ʻo nā nanotubes kalapona i hoʻopaʻa ʻia hoʻokahi ka ʻāpana kikoʻī kikoʻī nui loa a me ka conductivity uila maikaʻi, hiki i ka electrode i hoʻomākaukau ʻia e nā nanotubes kalapona hiki ke hoʻomaikaʻi nui i ka capacitance o ka capacitor papa pālua.
Kiʻekiʻe kiʻekiʻe composite mea kahua:
ʻOiai ʻo nā nanotubes kalapona paʻa hoʻokahi ka ʻano nanomaterials hoʻokahi-dimensional me ka microstructure kūʻokoʻa a maikaʻi loa a me ka lākiō hiʻohiʻona nui loa, ʻoi aku ka nui o nā hoʻokolohua i hōʻike ʻia i nā nanotubes kalapona paʻa hoʻokahi i loaʻa nā waiwai mechanical kupaianaha a lilo i ke ʻano hope loa o ka hoʻomākaukau ʻana super- nā composites ikaika.
E like me nā mea hoʻoikaika paʻa, ua lawe mua ʻia ke kalapona nanotubes ma luna o nā substrates metala, e like me ka carbon nanotubes iron matrix composites, carbon nanotubes aluminum matrix composites, carbon nanotubes nickel matrix composites, carbon nanotubes copper matrix composites.
Pākuʻi kahua:
Loaʻa i nā nanotubes kalapona paʻa hoʻokahi i nā waiwai hoʻokuʻu electron hoʻoheheʻe ʻia, hiki ke hoʻohana ʻia e hana i nā mea hōʻike planar ma kahi o ka ʻenehana cathode tube nui a kaumaha.Ua hōʻike nā mea noiʻi ma ke Kulanui o Kaleponi he kūpaʻa maikaʻi ke kūpaʻa a me ke kū'ē ʻana i ka pōʻino ion, a hiki ke hana i kahi ʻōpuni ʻūhā o 10-4Pa me ka nui o kēia manawa o 0.4A/cm3.
ʻO ka hoʻohana piha ʻana i nā waiwai uila a me nā mechanical:
