| Abstract: |
|
In this work we investigate the behavior of the electrical conductivity of polyaniline when small amounts of graphite nanolayers are added to the polymeric matrix and subsequently suffer an aging process. We observed that graphite tends to increase conductivity whilst aging tends to decrease it. On the other hand, absorption of atmospheric humidity tends to increase conductivity. We show that a mathematical model describes with good agreement the dependence of the conductivity with the aging time. |
