Conjugated polymers with main-chain heteroatoms: Synthesis
and properties of conductive polymer blends and composites
OBJECTIVES
1. Preparation and characterization of new conductive materials by
using the combination of various substituted PANIs and various
protonic dopants such as the bulky protonic and polymeric acids.
2. Development and optimization procedures for the preparation of
PANI blends and composites by mechanical mixing, casting of a
solution containing the components of the blend or ‘in situ’
polymerization of substituted anilines in the presence of the proper
conventional polymer.
3. The efficiency of the composites preparation and external doping
will be examined taking into account structure and properties of
materials prepared, particularly the optical, mechanical, thermal and
electronic properties.
