Stability of electrical self-oscillation in PANi-CSA/PMMA composites

Self-electrical oscillations in composites of 8% PANi-CSA in PMMA reported earlier have been seen in different samples. While the earlier samples showed a transition from very regular to chaotic behavior depending upon bias current, the new samples exhibit time evolution with an initial amplitude gr...

Description
Summary:Self-electrical oscillations in composites of 8% PANi-CSA in PMMA reported earlier have been seen in different samples. While the earlier samples showed a transition from very regular to chaotic behavior depending upon bias current, the new samples exhibit time evolution with an initial amplitude growth of the oscillations followed by steady smaller amplitude oscillations, gradually diminishing for most conditions. Very different detailed behavior in similarly prepared samples has been observed and are compared.
