Abstract Conducting reticulate doped polymer (RDP) films with transparent appearance were prepared by the two‐step method. Polycarbonate films were doped with the bis(ethylenedioxy)tetrathiafulvalene (BEDO‐TTF) complex of ${\rm ReO}_{{\rm 4}}^{- } $ , Br − , ${\rm C(CN)}_{{\rm 3}}^{- } $ , or ${\rm C}_{{\rm 2}} {\rm O}_{{\rm 4}}^{{\rm 2}- } $ , the surface resistivities of which were 1.5, 1.4, 30, and 8.0 kΩ/□, respectively. The films containing ${\rm ReO}_{{\rm 4}}^{- } $ and Br − complexes showed quasi‐reversible humidity dependent behaviors, in which the resistivity and inter‐conducting‐layer distance were increased and decreased, respectively, in dry atmosphere. The ReO 4 containing film exhibited better reversibility, while the existence of two kinds of crystal structures was proved for the Br complex.
