Scholarcy highlights

  • Blending polyaniline with a host polymer has the advantage of reducing the amount of polyaniline necessary for conductivity, increasing the stability of this conduction, and enhancing the overall mechanical integrity, versatility, and processability of PAn
  • We have found PAn to be miscible with poly(vinyl pyrrolidone) under certain processing conditions
  • The extent of this compatibility and resulting mechanical properties were assessed by DMA, DSC, TGA, SAXS, and light microscopy
  • TGA results show that NMP binds very tightly to both PAn and PVP, with solvent cast blends retaining up to 20 wt% NMP, even after relatively vigorous drying
  • W.B. Stockton and M.F. Rubner, to be published in “Polymer Preprints”, ACS Meeting, San Diego, March 1994
