Abstract:
We report on observations of the behavior in single-wall carbon nanotubes (SWCNTs) and polymer nanocomposites, which may indicate that the conductivity of this nanomaterial undergoes chaotic changes under certain circumstances. We present interesting material properties that can be used for (a) investigating non-linearity / chaotic behavioral properties of the material, (b) understanding the underlying physics that may be explored by evolution, and (c) identifying appropriate signal types (voltages, frequencies) suitable to stimulate the material and demonstrate a computationally rich behavior. The presented results show that the investigated material is particularly sensitive to specific frequencies, e.g., square waves, and suggest that different behavioral regimes may be achieved, e.g., uniform, stable, chaotic. This work is done within the NASCENCE project, whose goal is to find new materials suitable to perform computation.
