摘要：

Molecular motions and thermal transitions in polyaniline fibers (circle divide=50 mu m), 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. (c) 2005 Elsevier B.V. All rights reserved.
