MULTI-WALL CARBON NANOTUBE NETWORKS PREPARED FROM PURE MWCNT AND THEIR OXIDISED FORMS EFFECT OF COMPRESSIVE STRAIN ON ELECTRIC RESISTENCE

Popis výsledku v původním jazyce

Multi-wall carbon nanotube networks were prepared by process of filtration of CNT aqueous dispersions. CNT dispersions were prepared with help of surfactant system (Sodium dodecyl sulfate with amylalcohol) by ultrasonication. Three types of MWCNT tubes were used. The first were pure CNT material delivered by supplier. The other were chemically treated in aim to prepare CNT oxidised forms (1. acid solution of KMnO4, 2. mixture of acids H2SO4 + HNO3). It was found that chemical modification significantlychanges properties of prepared carbon nanotube networks (?Buckypaper?). There were observed differences in porous structure between all of the forms analysed by SEM microscopy. Further, apparent density of prepared ?Buckypapers? changes in respect of used CNT material leading to different porosity of Buckypapers. Electrical resistance is also affected by process of MWCNT oxidation together with its temperature dependence. Effect of compressive strain on electric resistance of multi-wall
