“…Extensive research on several conjugated polymers including poly(p-phenylene), polyaniline (PANI), polypyrrole, polythiophene, polyindole, polycarbazole, polyfluorene, poly(p-phenylenevinylene), and their substituted derivatives have led to their applications in rechargeable batteries, microelectronics, sensors, electrochromic displays, and light-emitting and photovoltaic devices [2,3]. Among the various conjugated polymers, PANI (Scheme 1) has received special recognition owing to its good stability and interesting redox behavior [4][5][6][7][8][9].…”

Abstract:The key developments in polyaniline-carbon nanotube (PANI-CNT) composites are reviewed. Apart from in situ chemical polymerization and electrochemical deposition, a number of interesting approaches including the use of aniline functionalized CNTs and ultrasound/microwave/γ-radiation initiated polymerization have been used in the preparation of composites. The structure and properties of these composites have been investigated by a variety of techniques including absorption, infrared (IR), Raman, X-ray photoelectron spectroscopy methods, scanning electron and scanning probe microscopy techniques, cyclic voltammetry, and thermogravimetry. The experimental results indicate favorable interaction between PANI and CNTs. The CNT content in these composites controls their conductive, mechanical, and thermal properties. The most interesting characteristic is their easy dispersibility in aqueous solution. The performance evaluation studies of PANI-CNT composites in a number of applications including supercapacitors, fuel cells, sensors, and actuators are highlighted.

“…7 To date a tremendous amount of research has been carried out in the field of conducting polymers, while the broader significance of the field was recognised in the year 2000 with the awarding of the Nobel Prize for Chemistry to the three discoverers of ICPs, Shirakawa, MacDiarmid and Heeger. 3,29 Since the discovery of conducting PAc, a number of additional ICPs have been developed, including polypyrrole (PPy), [30][31][32][33][34] polyaniline (PAni), [35][36][37] polythiophene (PTh), 38,39 poly(p-phenylenevinylene) (PPV), 40,41 poly(3,4-ethylene dioxythiophene) (PEDOT), 3,[42][43][44] and polyfuran (PF). 45 The structures of selected conducting polymers are illustrated in Figure 1.…”

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.

“…Of the many ICPs currently available (see Skotheim et al 1998;Chandrasekhar 1999;Wallace et al 2003), the polypyrroles (PPys) have proven most effective for biological applications. The polymers can be grown at neutral pH from aqueous media, enabling incorporation of delicate biological molecules such as antibodies, enzymes, anticoagulants, growth factors or even whole living cells at the point of synthesis (Kane-Maguire and Wallace 2002).…”

Abstract:The development of the multiple-channel bionic ear for hearing and speech understanding in profoundly deaf people is the result of integrating biological and physical sciences with engineering. It is the first clinically successful restoration of sensory and brain function, and brings electronic technology into a direct functional relationship with human consciousness. It presently transmits essential place and coarse temporal information for the coding of frequency, but the fine temporal and place excitation of groups of nerve fibres is inadequate for high-fidelity sound. This is required for adequate musical appreciation and hearing in noise. Research has demonstrated that nerve growth factors preserve the peripheral processes of the auditory nerves so that an electrode array placed close to these fibres could produce this fine temporal and spatial coding. The nerve growth factors can be incorporated into inherently conducting polymers that are part of the array so the peripheral processes can be preserved at the same time as they are electrically stimulated.
