In this article, we report the preparation of
conducting natural rubber (NR) with polyaniline (Pani). NR
was made into a conductive material by the compounding
of NR with Pani in powder form. NR latex was made into a
conductive material by the in situ polymerization of aniline
in the presence of NR latex. Different compositions of Pani-
NR semi-interpenetrating networks were prepared, and the
dielectric properties of all of the samples were determined
in microwave frequencies. The cavity perturbation techpique was used for this study. A HP8510 vector network analyzer
with a rectangular cavity resonator was used for this
study. S bands 2-4 GHz in frequency were used. Thermal
studies were also carried out with thermogravimetric analysis
and differential scanning calorimetry.
