“…[81] The same group fabricated poly(pyrrole) (PPy) microwires (PPYμWs) on flexible substrates including PETE, cyclic olefin copolymer, polyethylene naphthalate, and PI using microcontact printing (μCP). [82] The flexible sensors demonstrated multiplex cytokine detection by impedance spectroscopy. PPy is a good conductive polymer for electrical biosensors due to its electrical conductivity, environmental stability, biocompatibility, and easy synthesis.…”

“…PPy thin film can be prepared by crosslinking with phytic acid, and PPy‐based membranes can be applied to various material sciences in practical engineering fields, such as in biosensors, bioactuators, tissue engineering, and drug delivery. Diverse fabrication methods have been adopted to improve the PPy performance, because well‐defined architectures are highly important in material sciences, nanotechnology, and bioengineering . However, the precise patterning of architectures is still a major challenge because the conventional technologies that produce designed CPs have poor reproducibility, require multiple fabrication steps, and are hence expensive, time‐consuming, and difficult to scale up …”

Polypyrrole (PPy) is a promising conductive polymer (CP) with electrical versatility, easy synthesis and functionalization, stability, and biocompatibility. Diverse architectures have been adopted to improve PPy performance, but the direct and precise patterning of various architectures remains challenging. Here, the unique formation of a PPy membrane on the air/water interface of a droplet solution containing ammonium persulfate and phytic acid is investigated. When a PPy thin film forms on the air/water interface, the top of the droplet rapidly flattens. The formation procedure and final structure of the PPy thin film are visualized and quantitatively investigated. Unlike the typical globular structure of PPy, the self‐assembled PPy film surface fabricated in this study is very organized and regularly shaped. This well‐ordered membrane may have a very high buckling strength greater than the surface tension of the solution. The proposed precise fabrication method is simple and inexpensive for fabricating patterned functional membranes. These results provide new insight into the fabrication of CP and their applications in various practical electromaterial engineering fields.

“…Not surprisingly, the targeted functionalization with monomers of conductive polymers and subsequent polymerization opens new possibilities for several technological applications such as biosensing, supercapacitor, artificial muscles, smart membranes, and smart drug delivery . Carbonaceous materials with conductive polymers already manifest a great potential as supercapacitor (SC) as shown by the non‐covalently bonded composite sulfonated graphene/polypyrrole which provide a high specific capacitance of 310 F g −1 .…”

Graphene-based nanocomposites with conducting polymers have attracted increasing interest due to the enhanced synergistic properties, which can potentiate and broaden applications. In this context, covalent functionalization stands out as a strategic designing tool, which optimizes the interaction between the nanocomposites components. Herein, covalently linked polymeric nanocomposites were obtained between graphene derivatives and polypyrrole (Ppy) under mild routes (i.e., aqueous, room temperature). First, pyrrole was covalently functionalized on graphene oxide (GO) through stable amide bonds and further polymerization with FeCl 3 led to the polymeric nanocomposites. Finally, to improve conductivity, GO was reduced using NaBH 4 . Similarly, analogous noncovalent nanocomposites were obtained for comparison purposes. All samples were thoroughly characterized by thermogravimetric analysis, scanning electron microscopy, and infrared and Raman spectroscopy, confirming the targeted functionalization, polymerization, and reduction processes. Moreover, the covalent link effectively enhances the interaction of the nanocomposite's components as evidenced by its improved electrochemical stability (300 cycles), compared to the non-covalent composites which loses conductivity in the initial stages. Indeed, Ppy is known for its low stability, limiting its applications. Overall, the results herein evidence that covalently linked nanocomposites can be successfully obtained with optimized electrochemical response, promising for applications as supercapacitors and artificial muscles.
