Abstract:
The thesis deals with the preparation and dielectric characterization of
Poly aniline and its analogues in ISM band frequency of 2-4 GHz that includes part
of the microwave region (300 MHz to 300 GHz) of the electromagnetic spectrum
and an initial dielectric study in the high frequency [O.05MHz-13 MHz].
PolyaniIine has been synthesized by an in situ doping reaction under different
temperature and in the presence of inorganic dopants such as HCl H2S04, HN03,
HCl04 and organic dopants such as camphorsulphonic acid [CSA],
toluenesulphonic acid {TSA) and naphthalenesulphonic acid [NSA]. The variation
in dielectric properties with change in reaction temperature, dopants and
frequency has been studied. The effect of codopants and microemulsions on the dielectric properties has also been studied in the ISM band. The ISM band of
frequencies (2-4 GHz) is of great utility in Industrial, Scientific and Medical (ISM)
applications. Microwave heating is a very efficient method of heating dielectric
materials and is extensively used in industrial as well as household heating
applications.
