Abstract: C1.00044 : Thermal Properties of specific Nonconjugated Conductive Polymers studied using Differential Scanning Calorimetry
Author:
Differential scanning calorimeter (DSC) has been used to measure
the thermal
properties of nonconjugated conductive polymers, poly($\beta
$-pinene) and
trans-1,4-polyisoprene before and after doping with iodine. The
measurements
have been made over the temperature range of -50 $^{\circ}$C to
110$^{\circ}$C. The
heat capacity of poly($\beta $-pinene) has been observed to
increase upon
iodine doping. The T$_{g}$ of undoped poly($\beta $-pinene) and
the T$_{m}$
of undoped trans-1,4-polyisoprene have been measured and were
found to be 77
$^{\circ}$C and 60 $^{\circ}$C respectively. After doping the
T$_{g}$ and T$_{m}$
transitions were not clearly observable. X-ray diffraction
studies have
shown the $\gamma $-phase crystal structure for
trans-1,4-polyisoprene film
in the undoped state. These results will be discussed considering
the
molecular and nano-structures of these materials before and after
doping.
