“…Linear conducting polymer (CP) actuators have been widely studied during the last decades [1][2][3] with main focus on optimization towards maximum strain and stress. PPy/LiTFSI and PPy/TBACF 3 SO 3 linear actuators have shown strains as high as 20% [1,4] and stress in range of 10-20 MPa [4].…”

Co-doping polypyrrole (PPy) with dodecylbenzenesulfonate and multicharged phosphotungstate anions (PT) from the phosphotungstic acid (PTA) led to free-standing PPy/DBS-PT films, which were studied for their linear actuation properties. FTIR and Raman spectra revealed that PT was successfully embedded in PPy/DBS during electropolymerisation. Isometric stress and isotonic strain measurements in aqueous electrolyte under various electrochemical experiments showed an increase in the obtainable strain and stress, which was attributed to the electrocatalytic role PTA plays during the electropolymerisation. This results in lower synthesis potential and the formation of more compact films in comparison to PPy/DBS films under equal conditions. With the improved structure as well as the higher-charged immobilized PT dopant, 17 times higher conductivities, 1.7 times higher redox charge, and 1.8 times higher specific capacitance were obtained (at equal frequency). Energy dispersive X-ray (EDX) spectra indicated that contrary to some other published works, the majority of PT stayed stably in the film during consecutive redox cycles.

“…Chemical vapour deposition (CVD) (also known as vapour phase polymerisation) is another straightforward and rapid method to deposit PPy onto various substrates, and has been used widely to produce composite PPy fibres. 18,190,[203][204][205][206][207] Although this method has the advantage of simplicity, the highest reported electrical conductivity of fibres prepared this way was only 0.68 Scm -1 , 203 likely due to the formation of only a thin layer of conducting PPy. Nair and co-workers were the first to merge electrospinning with CVD for the synthesis of electrically conducting composite PPy nanofibres.…”

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.

“…Among the various organic materials reported in literature available to meet such requirements, conductive polymers such as Poly (3,4-ethylenedioxythiophene) (PEDOT) has a been popular choice that allow direct delivery of electrical, electrochemical and electromechanical signals at the electrode-tissue interface [1 , 6 , 17] . PEDOT-coated electrodes have been considered for biomedical [18] and bioelectronic applications [2 , 10 , 11 , 13] as well as in the fabrication of devices for neuronal interfaces [1 , 7] and electrochemical sensing and actuating devices [8 , 12 , 16] . On the other hand, carbon nanomaterials have displayed a wide array of key properties and are also promising candidate for such applications.…”

This present method describes a versatile approach for the electrochemical synthesis of a composite material of Poly (3,4-ethylenedioxythiophene) (PEDOT) and Carbon Nanofibers (CNFs) for neural interfaces and biosensing applications. Oxidized CNFs were utilized as dopants of PEDOT to prepare the composite coating through electrochemical deposition on microelectrodes arrays (MEA). The experimental results of this study showed that PEDOT:CNF microelectrodes exhibit remarkable electrochemical properties, combining low impedance, high surface area, high charge injection capability and reliable neurotransmitters monitoring using amperometric techniques. Taken together, these results suggest the great potential of PEDOT:CNF composite for developing next-generation multifunctional microelectrodes for applications in neural therapies. A simple approach for the electrochemical synthesis of PEDOT:CNF composite material on microelectrodes for neural interfaces and neurochemical sensing. PEDOT:CNF microelectrodes exhibit remarkable electrochemical properties, combining low impedance and high charge injection capabilities. PEDOT:CNF microelectrodes allowed the reliable detection of neurotransmitters with improved sensitivity.
