Dopant Loss

ABSTRACTA series of highly conductive, environmentally and thermally stable polyanilines was synthesized. These polymers, which are obtained by employing careful synthetic conditions, purification procedures, and dopant variations, show interesting morphological structures and high temperature stability. Thermal studies by TGA, DSC and DMTA show a glass transition temperature (Tg) for neutral polyaniline around 185°C. This is the same temperature at which the conductivity and crystallinity decrease. Isothermal heatings of the polyaniline tosylate at 200 and 250°C in air show significant amounts of weight loss. This is due to dopant loss through irreversible chain rearrangements and air oxidation at temperatures above Tg.

Conducting polymers comprises a new class of materials achieving electrical conductivities which rival those of the best metals. The parent compounds (conjugated polymers) are quasi-one-dimensional semiconductors. These polymers can be doped by electron acceptors or electron donors. The prototype of these materials is polyacetylene (PA). There are various other conjugated polymers such as polyparaphenylene, polyphenylenevinylene, polypoyrrole or polythiophene. The doped systems, i.e. the conducting polymers, have intersting potential technological applications such as replacement of conventional metals in electronic shielding and antistatic equipment, rechargable batteries, and flexible light emitting diodes.Although these systems have been investigated almost 20 years, the electronic structure of the doped metallic systems is not clear and even the reason for the gap in undoped semiconducting systems is under discussion.
