Abstract: | Composite materials based on the multiwall nanotubes (content in the material from 1 to 65 wt %) and polyaniline are prepared
and characterized. The composite materials are prepared by four methods: chemical synthesis, electrochemical synthesis, mixing
of dry components, and mixing of solutions with subsequent removal of solvent. The results of calculations of the specific
capacity of the composite materials, as well as their conductivity, stability, and behavior under the conditions of charging-discharging
point out to their applicability in devices for the energy storage. The range of critical changes in the values of specific
capacity and conductivity falls into the interval of the multiwall nanotubes content in the composite from 5 to 25 wt %. The
composite materials preparation methods used in this work enable one to choose an appropriate composite preparation method
reasoning from the final purpose of its application (obtaining of high capacity or conductivity). The carbon nanotubes, the
body of the composite, with their stable electronic conduction, can sustain the composite’s electrical conductivity at reasonable
level irrespective of the properties of the second component (polyaniline) in the case in question. |
