Fully exfoliated nanocomposite from polypyrrole graft copolymer/clay

Exfoliated polypyrrole graft copolymer/clay nanocomposites were prepared by in situ polymerization of pyrrole onto pre-exfoliated water-soluble poly(styrenesulfonic acid- co-pyrrolylmethyl styrene) (P(SSA- co-PMS))/clay nanocomposite or by simple blending of poly(styrenesulfonic acid- g-pyrrole) (PSSA- g-PPY) with clay. As the clay content in PSSA- g-PPY/clay nanocomposite increases, the conductivity of PSSA- g-PPY/clay nanocomposite decreases. Thermal de-doping temperature shifts to higher temperature as the clay content in PSSA- g-PPY/clay nanocomposite increases.
