Hony comb patterns and DC conductivity of cellulose multiwalled carbon nanotube composite films

Abstract

Cellulose triacetate (CTA) and functionalized multiwalled carbon nanotubes (MWCNTs) composites were prepared by dispersing different weight percentages of MCWNT in chloroform in the presence of CTA. A honeycomb-patterned film was fabricated by casting the chloroform solution on a glass plate under humid condition. The obtained ordered-structures with varying amounts of MWCNTs were analyzed by scanning electron microscopy (SEM). The room temperature direct current (DC) electrical conductivity and its dependence on the pore structure of the patterned films were also studied. The patterned films obtained in this study may have potential applications in electronics.
