Abstract: |
The large-area untrathin nano carbon tube film with well feature in microcosmic level comprises nano carbon tubes with centimeter-level length and more then 90wt% purity. Wherein, the least thickness of single-layer film can achieve 20nm with near transparent color and more then 10cm2 film area; there are multiple functional groups on tube surface. It also discloses the opposite preparation technique: with the macroscopic body of nano carbon tube, oxidating the macroscopic body in air; then, dipping into hydroperoxide; adding strong acid to poach till the liquid shows neutrality; finally, adding alcohol or acetone into the liquid to float the tube and form the film. |
