Fabrication Of An Electrically Conducting Full-Interpenetrating Polymer Network
Full-interpenetrating polymer networks (IPN) comprised of a styrene crosslinked polythiophene derivative and a crosslinked polystyrene network were synthesized and characterized. The IPNs were prepared by first crosslinking the pendant groups of a vinyl derivatized polythiophene with styrene monomer and then polymerizing and crosslinking styrene monomer in a swollen gel of the crosslinked polythiophene network. The doped forms of these full-IPNs reached conductivities as high as 0.5 S/cm. Conductivity stability studies showed that the IPNs are more stable than the as-prepared conjugated polymer at 40 °C but somewhat less stable at 80 °C.
