Txij li thaum lawv nrhiav tau nyob rau hauv 1991, carbon nanotubes tau txais kev pom zoo los ntawm cov kws tshawb fawb hauv kev lag luam chemistry, physics, thiab cov ntaub ntawv tshawb fawb.Txawm li cas los xij, vim tias cov pa roj carbon nanotubes yooj yim heev rau agglomerate, lawv tsis yooj yim tawg mus rau hauv lub raj mis hauv kev siv tswv yim.Kev hloov kho tshuaj lom neeg ntawm cov pa roj carbon nanotubes los txhim kho lawv cov khoom saum npoo yog ib txoj hauv kev zoo los qhib qhov khoob no.Txoj kev hloov tshuaj lom neeg yog ua kom muaj tshuaj lom neeg ntawm cov pa roj carbon nanotubes thiab cov hloov kho kom hloov cov qauv saum 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 acids muaj zog los yog cov kua qaub sib xyaw kom oxidize qhov tsis xws luag ntawm cov pa roj carbon nanotubes los tsim cov carboxyl pawg.

COOH Multi Walled Carbon Nanotubes tuaj yeem siv rau hauv cov ntaub ntawv sib xyaw los txhim kho lawv cov kev ua tau zoo.Cov hauv qab no yog qee cov ntaub ntawv thiab kev tshawb fawb tau los siv:

Raws li ib tug heterogeneous nucleating tus neeg saib xyuas, CNT-COOH txo qhov nruab nrab loj ntawm phenolic ua npuas ncauj hlwb thiab ua rau kom lub cell ceev;Raws li cov ntsiab lus ntawm CNTCOOH nyob rau hauv phenolic ua npuas ncauj nce, lub compression modulus thiab compression ntawm CNT-COOH / phenolic foam composite muaj zog nce.

Tom qab kev hloov kho carboxylation ntawm MWCNTs, cov khoom tawg hauv ABS matrix zoo dua, thiab kev ruaj ntseg zoo dua.Tib lub sijhawm, cov khoom siv kho tshuab ntawm ABS / MWCNTs-COOH cov khoom sib xyaw kuj tau txhim kho, thiab lub zog tensile kuj tseem txhim kho.Nyob rau hauv tus txheej txheem, ib tug network carbon txheej yuav raug tsim nyob rau saum npoo ntawm cov khoom los txhim kho cov nplaim retardant kev ua tau zoo ntawm cov khoom sib xyaw.
