- Abstract
The influence of ionic‐electronic coupling on the electrical conductivity and the photoconductivity of organic mixed ionic electronic conductor (OMIECs) of polyaniline/poly (4‐styrene sulfonic acid) (PANI/PSS) composite films. PANI/PSS composite films are connected by blending the carbon atoms within the aromatic ring in PANI with sulfonate groups in PSS. The electrical conductivity of PANI/PSS composite film increases from 0.80S.cm−1 to 1.23S.cm−1 as the pH value increases from 3 to 9. The electrical conductivity of PANI/PSS composite films for all pH values increases continuously as the temperature increases. Additionally, the PANI/PSS composite films exhibit photo responses at UV light since the band structure can absorb the light in this region. The photoconductivity curves of PANI/PSS composite films for different pH values exhibit good consistency and repeatability. Modeling raising photoconductivity and decaying conductivity after light off leads us to understand the underlying physics of the ionic‐electronic coupling and other parameters on the photoconductivity of OMIECs, consequently building OMIEC devices for different photoconductivity applications.
