Preparation of polystyrene/polyaniline blends by in situ polymerization technique and their morphology and electrical property

Electrically conducting polystyrene/polyaniline blends were prepared by in situ polymerization technique (method I), and simple solution blending (method II). Electrical conductivities of the blends prepared by method I are higher than those of the corresponding blends prepared by method II or any other methods. This is attributed to the fact that the blends prepared by method I have higher crystallinity and better homogeneous morphology than the blends prepared by method II. (C) 2002 Elsevier Science B.V.
