Residual water and electrical properties of polyaniline

Summary form only given. The work aims to study the mechanism of interaction between water molecules and polyaniline (PANI) backbone as an important constituent of acid-base transformations ensuring good conductive properties of PANI. Experiments have been made using chemically synthesized emeraldine base subjected to different chemical treatments and aging procedures. Thermogravimetric measurement have shown that water content in polymeric matrices may amount up to 20-25 wt.% with two distinguished reversible absorbance states of water molecules. Weakly bond water (3-5 kcal/mol) is incorporated into PANI from ambient atmosphere and could be eliminated by drying at room temperature in vacuu…
