Puas yog Boron Nitride Cov Carbon Tshiab? Ib Lub Zeem Muag, Sib Cais

Zoo li graphene, hexagonal boron nitride muaj cov qauv molecular zoo li qaib hlau. Hauv graphene, qhov kev teeb tsa qaib hlau no yog tsim los ntawm cov pa roj carbon atoms, npaj rau hauv cov qauv rov ua dua ntawm hexagons. Rau hBN, cov hexagons yog tsim los ntawm alternating atoms ntawm boron thiab nitrogen. Nyob rau hauv xyoo tas los no, cov kws tshawb fawb tau pom tias cov nplooj ntawv ob sab ntawm hBN nthuav tawm cov khoom tshwj xeeb ntawm lub zog, tawv, thiab kev ua haujlwm ntawm qhov kub thiab txias. Thaum cov nplooj ntawv ntawm hBN tau dov mus rau hauv daim ntawv nanotube, cov khoom no tau txhim kho ntxiv, tshwj xeeb tshaj yog thaum cov nanotubes raug sib dhos, zoo li cov ntoo me me hauv hav zoov uas muaj pob zeb loj.

Tab sis nrhiav txoj hauv kev los tsim kom muaj kev ruaj khov, zoo BNNTs tau ua pov thawj nyuaj. Ib txhais tes ntawm kev siv zog ua li ntawd tau tsim cov khoom tsis zoo, tsis muaj fiber ntau.

Wardle hais tias "Yog tias koj tuaj yeem kho lawv, koj muaj sijhawm zoo dua ntawm kev siv BNNTs cov khoom ntawm qhov loj me los ua cov khoom siv lub cev, cov khoom sib xyaw, thiab cov ntaub so ntswg," Wardle hais.

Xyoo 2020, Rong Xiang thiab cov npoj yaig ntawm University of Tokyo pom tias lawv tuaj yeem tsim cov khoom zoo boron nitride nanotubes los ntawm thawj zaug siv cov qauv ntawm cov tshuaj vapor deposition kom loj hlob hav zoov luv luv, ob peb micron-ntev carbon nanotubes. Tom qab ntawd lawv coated cov pa roj carbon-based hav zoov nrog "precursors" ntawm boron thiab nitrogen gas, uas thaum ci hauv qhov cub ntawm qhov kub thiab txias crystallized mus rau cov pa roj carbon nanotubes los tsim cov nanotubes zoo ntawm hexagonal boron nitride nrog carbon nanotubes hauv.
