“…These unconventional properties of an organic material encourage more and more interest numerous other conducting polymers with similar properties were synthesized, such as polypyrrole (PPy), polyaniline (PANI), polythiophene (PTh), and poly (3,4-ethylenedioxythiophene) (PEDOT) etc., were discovered [3,4]. Among various conductive polymers, PPy has been extensively studied because of its extensive applications in the fields of antistatic material, rechargeable batteries, sensors, printing circuit board, stealth material, electrochromic material, drug delivery and others owing to its high electrical conductivity, redox reversibility, good environment stability, good biocompatibility, relatively easy synthesis and low toxicity [5][6][7][8].…”

Nanostructured polypyrrole (PPy) was successfully prepared via template-free emulsion polymerization method. In this paper, we discuss the influence of polymerization conditions such as the types of doping agent, the reaction time, the reaction temperature, the types of oxidant, and the oxidant-pyrrole molar ratio on the yield and resistance of doped PPy. The results revealed that these factors had an important effect on yield and resistance properties of the doped PPy. When synthesized under the optimal reaction condition at 0 o C, the yield and resistance of the doped PPy were 66% and 0.12 Ω, respectively. In addition, the crystallinity, chemical structure and morphology of the doped nanostructured PPy under the optimal polymerization condition and the undoped PPy were characterized by X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscope. The results demonstrated that doped polypyrrole has the morphology of interconnected spherical structure and higher crystallinity.

Conducting polymers have received increasing attention in both fundamental research and various fields of application in recent decades, ranging in use from biomaterials to renewable energy storage devices. Processing of conducting polymers into fibrillar structures through spinning has provided some unique capabilities to their final applications. Compared with non fibrillar forms, conducting polymer fibres are expected to display improved properties arising mainly from their low dimensions, well-oriented polymer chains, light weight and large surface area to volume ratio. Spinning methods have been employed effectively to produce technological conducting fibres from nanoscale to hundreds of micrometre sizes with controlled properties. This review considers the history, categories, the latest research and development, pristine and composite conducting polymer fibres and current/future applications of them while focus on spinning methods related to conducting polymer fibres.

“…As the most studied conductive polymer, PPy has been synthesized by chemical oxidation using a radical initiator with an appropriate electrolyte solution [59,60] or by electrochemical oxidation of pyrrole with an electrolyte solution on a platinum-coated electrode [61]. PPy has been reported to offer focal adhesion and the growth of various cell types associated with endothelial cells [62,63], neurons, supporting cells (DRG) [64][65][66], and rat pheochromocytoma (PC12) cells [66][67][68][69]. Yang et al devised conductive hydrogels of hyaluronic acid and PPy that enhanced mechanical and conductive properties [70] (Figure 4).…”

In the field of tissue engineering, conductive hydrogels have been the most effective biomaterials to mimic the biological and electrical properties of tissues in the human body. The main advantages of conductive hydrogel include not only its physical properties, but also its adequate electrical properties, thus providing electrical signals to cells efficiently. However, when introducing a conductive material into a non-conductive hydrogel, a conflicting relationship between the electrical and mechanical properties may develop. This review examines the strengths and weaknesses of the generation of conductive hydrogels using various conductive materials and introduces the use of these conductive hydrogels in tissue engineering applications.
