Anglies nanovamzdeliai (CNT) - tai anglies alotropai, kurie yra cilindro formos korio formos ir nano skersmens. <\/p>\n\n\n\n

CNT pasi\u017eymi daugybe savybi\u0173, toki\u0173 kaip mechaninis stiprumas, elastingumas, lengvumas, elektrinis ir \u0161iluminis laidumas, tod\u0117l tai yra perspektyviausia med\u017eiaga. <\/p>\n\n\n\n

Daugelyje pramon\u0117s \u0161ak\u0173, \u012fskaitant elektronik\u0105, medicin\u0105, energijos kaupim\u0105, jutiklius ir daugel\u012f kit\u0173, CNT yra pla\u010diai naudojami. D\u0117l did\u0117jan\u010dios paklausos nuolat did\u0117ja CNT gamybos apimtys. <\/p>\n\n\n\n

\u0160i didelio masto CNT gamyba tapo pagrindiniu i\u0161\u0161\u016bkiu, trukdan\u010diu juos naudoti. <\/p>\n\n\n\n

I\u0161\u0161\u016bkio sprendimas :<\/p>\n\n\n\n

Paprastai mokslininkai renkasi auginti CNT mi\u0161kus, o ne auginti juos atskirai. CNT mi\u0161kai - tai vertikaliai i\u0161d\u0117styti CNT masyvai, kurie yra savaime surenkami. <\/p>\n\n\n\n

Paprastai tai atliekama cheminio nusodinimo i\u0161 gar\u0173 proceso metu, esant fiksuotam katalizatoriui ant pagrindo, kuris v\u0117liau atskiriamas nuo CNT mi\u0161ko, kad b\u016bt\u0173 gauta didelio grynumo med\u017eiaga. <\/p>\n\n\n\n

Nors \u0161is procesas turi daug privalum\u0173, vienintel\u0117 rimta problema, su kuria susiduriama, yra jo trukm\u0117. <\/p>\n\n\n\n

Iki \u0161iol mokslininkams pavyko u\u017eauginti iki 2 cm ilgio CNT mi\u0161k\u0105 naudojant gele\u017eies (Fe) katalizatorius ant aliuminio oksido (Al2O3) atramos (CNT ilgis yra labai svarbus j\u0173 savyb\u0117ms, tod\u0117l b\u016btina atsi\u017evelgti \u012f \u0161\u012f aspekt\u0105). <\/p>\n\n\n\n

Tai turi \u012ftakos jos pramoninei vertei, nes riboja pasi\u016bl\u0105 ir didina med\u017eiagos kain\u0105. <\/p>\n\n\n\n

Buvo padarytas revoliucinis atradimas, kuris visi\u0161kai pakeit\u0117 \u017eaidim\u0105. <\/p>\n\n\n\n

Neseniai Japonijos mokslinink\u0173 komanda, taikydama nauj\u0105 metod\u0105, u\u017efiksavo iki 14 cm ilgio CNT mi\u0161k\u0105. J\u0173 tyrimas neseniai buvo paskelbtas \u017eurnale \"Carbon\". <\/p>\n\n\n\n

Vasedos universiteto docentas Hisashi Sugime ir jo komanda nustat\u0117, kad CNT nustojo augti d\u0117l laipsni\u0161ko anks\u010diau naudoto katalizatoriaus (Fe-Al2Ox) strukt\u016bros poky\u010dio. <\/p>\n\n\n\n

I\u0161 esm\u0117s CNT tankis, kuris priklauso nuo aktyvi\u0173j\u0173 katalizatori\u0173 skai\u010diaus, yra nepakankamas, kad i\u0161laikyt\u0173 savaime i\u0161silaikan\u010di\u0105 strukt\u016br\u0105, ir mi\u0161ko augimas nutr\u016bksta. <\/p>\n\n\n\n

Tod\u0117l naudojamas katalizatorius turi i\u0161likti strukt\u016bri\u0161kai ir chemi\u0161kai stabilus.  <\/p>\n\n\n\n

J\u0173 metodas buvo pakeisti technik\u0105, kad \u0161is nestabilumas b\u016bt\u0173 nuslopintas. <\/p>\n\n\n\n

Jie tai pasiek\u0117 prid\u0117dami gadolinio (Gd) sluoksn\u012f prie ankstesnio katalizatoriaus, padengto n tipo silicio substratu. <\/p>\n\n\n\n

Gadolinio sluoksnis neleido katalizatoriui suirti, tod\u0117l CNT mi\u0161kas i\u0161augo 5 cm. <\/p>\n\n\n\n

Kad b\u016bt\u0173 pasiektas norimas ilgis, jie katalizatori\u0173 laik\u0117 kameroje, vadinamoje \u0161alt\u0173j\u0173 duj\u0173 cheminio nusodinimo i\u0161 gar\u0173 (CVD) kamera. <\/p>\n\n\n\n

Katalizatorius buvo i\u0161 anksto apdorotas palaikant temperat\u016br\u0105 iki 750 \u00b0C ir kambario temperat\u016broje leid\u017eiant nedidel\u0117s koncentracijos Fe ir Al garus. <\/p>\n\n\n\n

Tai pad\u0117jo i\u0161laikyti katalizatoriaus strukt\u016br\u0105 iki 26 valand\u0173, o tai savo ruo\u017etu skatino CNT mi\u0161ko augim\u0105. <\/p>\n\n\n\n

Atlikus kruop\u0161\u010dius tyrimus, pavyko u\u017efiksuoti 14 cm ilgio CNT mi\u0161ko ilg\u012f. <\/p>\n\n\n\n

J\u0173 pasiekimai atv\u0117r\u0117 naujus horizontus besivystan\u010dioms pramon\u0117s \u0161akoms.\u0160i reik\u0161minga pa\u017eanga i\u0161pl\u0117t\u0117 CNT taikymo aspektus. <\/p>\n\n\n\n

Tai gali pakeisti po\u017ei\u016br\u012f \u012f nanotechnologijas ir nanomoksl\u0105 b\u016bsimuose tyrimuose. <\/p>\n\n\n\n
