A new method of preparing conductive polymer composites by growing crystalline networks of conductive additives in polymer matrices (reticulate doping) is described. The method consists of treating the polymer containing molecularly dispersed donor additive with acceptorlsolvent vapors. In the swollen polymer layer simultaneously CT complex formation and crystallization takes place which for proper conditions leads to the formation of a network of the CT complex crystallites, making the film surface-conducting.The preparation and properties of surface conductive films using several electron donors and an iodine acceptor are described. The films obtained show surface resistivities of 104-106 ohm and are generally stable under ambient conditions.

“…26 To date, the bottleneck with coated and screen-printed electrodes is that the conducting layers are not an integral part of the base/ substrate on which the electrode is fabricated, and it can easily get delaminated by a mechanical jerk or high current. 27 Therefore, there is a need for an improved alternative to the surface-coated electrode having similar potentials but minimized shortcomings. In the current article, we report a different approach to fabricate a at and self-standing two-dimensional electrode using bulk conducting polymer composite.…”

We report an efficient plastic chip electrode (PCE) fabricated from a composite of graphite and poly(methyl methacrylate) by a simple solution casting method and promoted as an economically inexpensive, multipurpose disposable electrode for various applications. The TEM images of the filler (graphite) show that the material consists of single, as well as multi-layers. Thus, the self-standing and arid electrodes prepared were characterized for their material properties such as, microscopy (SEM and AFM), as well as thermal properties (TGA), mechanical (tensile strength) and electrical properties. A set of physical parameters were derived from these characterizations for sustainability of these electrodes in harsh off-laboratory conditions. The utility of these mechanically stable, bulk-conducting and high surface area electrodes were demonstrated in various well understood electrochemical protocols, such as cyclic voltammetry, stripping voltammetry, electropolymerization, electrowinning and amperometric sensing. The voltammetry data were compared with the data recorded on a conventional glassy carbon electrode.

“…Another modification was the “two-step reticulate doping”, in which the as-cast blend film is exposed to solvent vapor using a good solvent for the polymer, but rather poor ones for the dispersed small molecules. 23 Solvent vapor penetrates the polymer film and induces diffusion, nucleation, and subsequent crystallization of the small molecules in the blend film. This method is today commonly referred to as solvent vapor annealing (SVA).…”

Free-standing and flexible field-effect transistors based on 6,13-bis(triisopropylsilylethynyl)-pentacene (TIPS-pentacene)/polystyrene bilayers are obtained by well-controlled phase separation of both components. The phase separation is induced by solvent vapor annealing of initially amorphous blend films, leading to crystallization of TIPS-pentacene as the top layer. The crystallinity and blend morphology strongly depend on the molecular weight of polystyrene, and under optimized conditions, distinct phase separation with a well-defined and trap-free interface between both fractions is achieved. Due to the distinct bilayer morphology, the resulting flexible field-effect transistors reveal similar charge carrier mobilities as rigid devices and additionally pronounced environmental and bias stress stabilities. The performance of the flexible transistors remains stable up to a strain of 1.8%, while above this deformation, a close relation between current and strain is observed that is required for applications in strain sensors.
