Semi‐crystalline polypyrrole: Polystyrene sulfonate synthesized through the pores of filter paper

Semi‐crystalline polypyrrole:polystyrene sulfonate (PPy:PSS) composites were synthesized successfully after passing through the micro‐pores of filter paper. Filter paper was used as a tunnel to channel the diffusion speed of the initiator and to separate the PSS chains as a function of the occupied pore volume. Fourier transform infrared spectroscopy (FT‐IR) suggested the specific bonding structures of the formed PPy:PSS. The crystallographic structures of the PPy:PSS composites were analyzed by X‐ray diffraction based on various pore sizes of the filter paper used. The crystallinity dependence of the conductivity was evaluated using a standard four‐point probe. A series of PPy:PSS samples with different crystallinity exhibited electrical conductivity ranging from 0.007 S/cm to 0.062 S/cm. POLYM. ENG.
