Abstract
- Abstract: Molecular motions and thermal transitions in polyaniline fibers (∅=50 μm), cast from emeraldine base powder dissolved in N,N′-dimethylpropylene urea (DMPU), have been investigated by dynamic mechanical thermal analysis (DMTA). For this purpose, a special picopendulum has been used, and a double sweep DMTA study has been performed. From these preliminary experiments, different relaxations observed have been discussed and compared to what is found in the literature. [Copyright &y& Elsevier]
