High Aspect Ratio SWCNT hmoov

Yog tias koj twb tau sim tsim ib qho kev sib txuas nrog cov raj luv luv, koj twb paub qhov kev sib haum xeeb: koj xav tau kev thauj khoom siab dua kom tau cov electrons dhia ntawm ib feem mus rau lwm qhov, thiab mam li nco dheev koj cov resin tag nrho ntawm qhov hnyav tuag uas tsis muaj dab tsi rau txhua yam muaj zog. Lub physics ntawm no yog unforgiving - conductivity nyob rau hauv ib tug nanotube network tsis yog hais txog txoj kab uas hla; nws yog hais txogncav cuag. Qhov sib piv siab ntawm ib phab ntsa carbon nanotube (SWCNT) tsis yog zaum ntawd; Nws spans qhov khoob, txuas txuas cov khoom nquag, thiab weaves ib mesh ntawm loadings tsawg (<0.05%) that you forget it's there until you measure the sheet resistance.

Cov neeg muag khoom feem ntau yuav muag koj "ntev" cov raj uas tau txiav cov khoom ntawm CVD lub txaj ntxuav. NtawmShandong Tanfeng, peb tsis txiav cov ces kaum - lus. Peb kho peb cov ntab ntab -catalyst CVD lub sijhawm nyob kom loj hlob cov raj uas tsis tu ncuantev ntawm 10-30 µmpe ib1-2 nm txoj kab uas hla, thawb nam piv dhau10,000:1. Qhov no tsis yog ib qho spec ntawm ntawv xwb; nws yog qhov sib txawv ntawm cov saw tsis yooj yim thiab lub vev xaib uas muaj zog.

Vim Li Cas Aspect Ratio Yog Tus Neeg Ua Phem Tsis Txaus Siab (lossis Cawm Seej)

Hauv cov roj teeb anodes, tshwj xeeb tshaj yog silicon -carbon blends qhov twg cov khoom swells 300%, cov raj luv luv tau ripped sib nrug. High nam piv SWCNTs ua zoo li microscopic springs -lawv stretch nrog nthuav thiab snap rov qab, ua kom txoj kev loj electron qhib. Hauv cov yeeb yaj kiab pob tshab, koj xav tau ntev los txuas cov dots yam tsis muaj piling ntawm ntau yam khoom uas koj tua cov optics.

Nov yog qhov kev muaj tiag uas phem heev thaum koj sib piv dab tsi ntawm kev ua lag luam piv rau qhov ua tau zoo hauv kev tsim khoom:

Shandong Tanfeng Ntug: Loj hlob, Tsis Sib Tsoo

Koj ua tsis tauuasiab nam piv raj los ntawm kev sib tsoo cia agglomerates; koj yuav tsum tau loj hlob nws ntev thiab ua kom nws ruaj khov. Qhov ntawd yog qhov uas cov tub lag luam poob thiabShandong Tanfengcoj:

Residence Time Mastery: Peb cov reactors yog calibrated kom txo tau ntxov ntxov txiav ntawm kev loj hlob. Peb tsis tsuas yog crank qhov kub thiab txias; peb sib npaug carbon feedstock thiab catalyst kinetics kom txhawb nqa kev loj hlob ntawm axial yam tsis muaj ntau amorphous carbon wrapping.

Tsawg-Kev puas tsuaj: High AR raj yog qhov tsis yooj yim. Peb cov ntawv tshaj tawm -synthesis tuav kom tsis txhob muaj qhov siab - shear, puas milling uas hloov cov raj ntev mus rau hauv cov hmoov av kim. Dab tsi tawm peb kab yog fluffy, entangled, tab sistsis zoo.

Purification Tsis muaj truncation: Tshem tawm Fe / Co / Ni catalysts (<50 ppm standard) usually risks oxidizing tube ends. Our selective acid treatment and thermal protocols strip metal without nibbling away at tube length, preserving that critical aspect ratio.

Morphology Xauv: Txawm hais tias koj noj 500g lossis 1000kg, qhov kev faib tawm ntev yuav raug kaw. Peb tsis muab cov khoom sib xyaw kom tau raws li qhov tshwj xeeb -peb ua ke rau lub qhov rais.

Koj siv qhov twg

Cov hmoov no yog tsim rau cov ntawv thov uas "zoo txaus" conductivity ruins tus so ntawm cov mis:

Transparent Conductive Films (TCFs): Ua tiav<100 Ω/sq without losing >90% kev xa tawm.

Siab -Frequency EMI Shielding Composites: Cov raj ntev tsim ntau- cov ntsiab lus tiv tauj uas cuam tshuam / nqus ntawm cov kab dav dav.

Luam tawm / Flexible Electronics: Khoov lub raj 10µm yooj yim dua li snapping luv luv; lub voj voog lub neej txhim kho drastic.
