The electrical properties of polymers make up an inherently interdisciplinary topic,
being closely associated, on the one hand, with the mechanical properties of polymers
polarization and relaxation) and, on the other hand, with the semi conductive
properties (conduction and break down). In addition, unlike conventional
technologies, which use these properties in its various applications like antistatic
coatings, rechargeable batteries, sensors, electrochromic devices, electrochemical
devices etc, microwave technology extract the microwave absorbing ability of
electrically conducting polymers. The conducting polymers are widely used in its
potential applications like electro magnetic interference shielding, satellite
communication links, beam steering radars, frequency selective surfaces etc.
Considering the relevance of microwave applications of conducting polymers, the
study of microwave properties of conducting polymers stands poised to become a
compelling choice for synthetic chemists and condensed - matter physicists, physical
chemists and material scientists, electrochemists and polymer scientists.
The main aim of the present work is to study the microwave and low frequency
properties of various conducting polymers, conducting semi-interpenetrating
networks, conducting copolymers and to characterise it. Also this thesis collated the
microwave properties of these conducting systems and exposes the various
technologically important applications in the industrial, scientific, communication and
defence applications. |
