The fabrications of regularly ordered structure in the MWNT are reported. The regularly ordered honeycomb patterned arrangement of MWNT film was prepared by calcinations of patterned cellulose triacetate/MWNT composite films. The composites were prepared by the dispersion of pretreated MWNTs into the CTA solution in chloroform with varying amounts of MWNT (10, 20, and 30 w/w%). Highly ordered polymer films of the composites are produced by evaporating a solution of polymer dissolved in a volatile solvent under humid conditions. After preparing a patterned porous polymer film by the composites, the polymer films are calcinated at about 300 o C. Then pure MWNT film with patterned structure was obtained by the degradation of all the organic components. Depending on the MWNT amount, the pattern was varied. |
