Abstract:
Solid electrolytes for applications like
chemical sensing, energy storage, and conversion have been
actively investigated and developed since the early
sixties. Although of immense potential, solid state
protonic conductors have been ignored in comparison with
the great interest that has been shown to other ionic
conductors like lithium and silver ion conductors. The
non-availability of good, stable protonic conductors could
be partly the reason for this situation. Although organic
solids are better known for their electrical insulating
character, ionic conductors of organic origin constitute a
recent addition to the class of ionic conductors.
However, detailed studies (N1 such conductors are scarce.
Also the last decade has witnessed an unprecedented boom
in research on organic "conducting polymers". These newly
devised materials show conductivity spanning from
insulator to metallic regimes, which can be manipulated by
appropriate chemical treatment. They find applications in
devices ranging from rechargeable batteries to "smart
windows".
This thesis mainly deals with the synthesis and
investigations on the electrical properties of (i) certain organbc protonic conductors derived from ethylenediamine
and (ii) substituted polyanilines
