Sharaxaad:
Tan iyo markii la helay 1991, kaarboon nanotubes waxaa door biday cilmi-baarayaasha dhinacyada kimistariga, fiisigiska, iyo sayniska agabka.Si kastaba ha ahaatee, sababtoo ah nanotubes kaarboon aad bay u fududahay in la kiciyo, si fudud looguma kala firdhiyo cirridka codsiyada la taaban karo.Wax ka beddelka kiimikada dusha sare ee kaarboon nanotubes si loo hagaajiyo hantidooda dusha sare waa hab wax ku ool ah oo lagu furo dhalooyinkan.Habka wax ka beddelka kiimikaadku waa in la sameeyo fal-celin kiimikaad oo u dhexeeya kaarboon nanotubes iyo beddelka si loo beddelo qaab-dhismeedka dusha sare iyo xaaladda kaarboon nanotubes-ka, si loo gaadho ujeedada wax ka beddelka.Mid ka mid ah kuwa ugu badan ee la isticmaalo waa asiidh xooggan ama asiidh isku dhafan si ay u oksijiyeen ciladaha dusha sare ee nanotubeska kaarboon si ay u sameeyaan kooxo karboksyl ah.
COOH Multi Walled Carbon Nanotubes waxaa loo isticmaali karaa walxo isku dhafan si loo hagaajiyo waxqabadkooda.Kuwa soo socda waa qaar ka mid ah waraaqaha iyo natiijooyinka cilmi-baarista ee tixraaca:
Sida wakiilka nukleating heterogeneous, CNT-COOH waxay yaraynaysaa qiyaasta celceliska unugyada xumbo phenolic waxayna kordhisaa cufnaanta unugyada;sida waxa ku jira CNTCOOH ee xumbo phenolic ay korodho, modules-ka isku-buufinta iyo isku-buufinta CNT-COOH / phenolic foam composite Strength ayaa kordhay.
Ka dib markii la beddelo karboksylation ee MWCNTs, kala firidhsanaanta walxaha matrix ABS waa la wanaajiyey, xasiloonidana waa la wanaajiyey.Isla mar ahaantaana, sifooyinka farsamada ee ABS / MWCNTs-COOH walxaha isku dhafan ayaa sidoo kale la wanaajiyey, iyo xoogga xajinta ayaa sidoo kale la wanaajiyey.Inta lagu jiro habka, lakabka kaarboonka shabakad ayaa laga samayn doonaa dusha sare ee alaabta si loo hagaajiyo waxqabadka ololka ee walxaha isku dhafan.
Xaaladda Kaydinta:
COOH shaqaynaysa MWCNT Short waa in si fiican loo xidhaa, lagu kaydiyaa meel qabow oo qalalan, iska ilaali iftiinka tooska ah.Kaydinta heerkulka qolku waa OK.
