Txij li thaum lawv tshawb pom hauv 1991, cov nanotubes tau nyiam los ntawm cov kws tshawb nrhiav hauv cov duab Chemistry, physics, thiab cov ntaub ntawv kawm txuj ci. Txawm li cas los xij, vim tias cov nanotubes muaj yooj yim heev rau agglomerate, lawv tsis yooj yim dispersed rau hauv ib qho kev thov siv. Kev Hloov Teeb Kev Hloov Kho Cov Tshuaj Kho Mob ntawm cov Nanotubes txhawm rau txhim kho lawv cov khoom saum npoo av yog ib txoj hauv kev kom qhib cov hliav no. Kev hloov kho tshuaj lom neeg yog ua kom cov tshuaj lom neeg ntawm cov pa roj carbon nanotubes thiab cov hloov kho kom hloov cov txheej txheem npoo thiab lub xeev ntawm cov pa roj carbon nanotubes, thiaj li ua tiav lub hom phiaj ntawm kev hloov kho. Ib qho ntawm feem ntau siv yog cov muaj zog acids lossis sib xyaw acids rau oxidize thiab cov pa roj carbon monoxide ntawm cov pa roj carbox.

Cooh multi walled carbon nanotubes tuaj yeem siv rau hauv cov khoom siv sib xyaw los txhim kho lawv cov kev ua tau zoo. Cov hauv qab no yog qee cov ntaub ntawv thiab cov txiaj ntsig tshawb fawb rau kev siv:

Raws li tus neeg saib xyuas heterogeneous nucleating nucleating tus neeg saib xyuas, cnt-board txo qhov nruab nrab loj ntawm phenol foam hlwb thiab ua kom lub cell ntom ntom; Raws li cov ntsiab lus ntawm CNTCOOH hauv Phenolic ua npuas dej nce, cov compression modulus thiab compression ntawm CNT-ROAM / phenolic ua npuas ncauj tsim kom muaj zog ntxiv.

Tom qab kev hloov kho carboxylation ntawm mwcnts, cov dispersion hauv ab ab matrix cov khoom yog txhim kho, thiab kev ruaj khov yog hloov kho. Nyob rau tib lub sijhawm, cov cuab yeej siv cov neeg kho mob ntawm Abs / MWCNTs-Cooh Composite, thiab lub zog tensile kuj tseem txhim kho. Nyob rau hauv cov txheej txheem, lub network carbon roj carbon las yuav tsim nyob rau saum npoo ntawm cov khoom los txhim kho cov nplaim retardant kev ua haujlwm ntawm cov khoom siv sib xyaw.
