Book Description
This book provides a comprehensive overview on the recent significant advancements of conductive polymers and their composites in terms of conductive mechanism, fabrication strategies, important properties, and various promising applications. The corresponding knowledge was systematically compiled in the logical order and demonstrated as seven chapters. The special structure, influencing factors of the conductivity, the charge carrier transport model, the wettability and classical categories of the conductive polymers are narrated. Both conventional and novel strategies undertaken to fabricate the conductive polymers are introduced, as provided the overall master of the progress. In comparison with the bulk counterpart, nanostructured conductive polymers with different dimensions such as nanospheres, nano-networks, nanotubes and nanowire arrays are produced through distinct methods, thus presenting unique and distinct performance endowed by the nanometer scale. The combination of conductive polymers with other functional materials results in a number of the composites with improved properties by synergistic effect. The superior performance of conductive polymers and their composites greatly facilitates their development toward various important applications in the advanced and sophisticated fields such as biological utilization, energy storage and sensors. Due to their excellent biocompatibility, conductive polymers and their composites stand out to be useful in the biological field including tissue engineering, drug delivery and artificial muscle. To meet the urgent demand of the energy storage, conductive polymers and their composites play an important role in the devices including supercapacitors, solar cells and fuel cells. Finally, development of conductive polymers and their composites in the modern industry is greatly enhanced by their applications in smart sensors such as conductometric sensors, gravimetric sensors, optical sensors, chemical sensors and biosensors. This book has significant value for researchers, graduate students, and engineers carrying out the fundamental research or industrial production of conductive polymers and their composites.

Book Description
Conducting polymer nanocomposites exhibit for instance interesting thermoelectric properties which make them a promising, inexpensive, clean and efficient solution for heat waste harvesting. This thesis reports on properties of polyaniline (PANI) nanostructured composites as a function of various carbonaceous nano-fillers content such as carbon nanotubes (1-D), and 2-D reduced graphene oxide (RGO). SEM, TEM, X-ray diffraction, and Raman spectroscopy have been employed to investigate their structure and morphology. Electrical and thermal conductivity, Seebeck coefficient, and thermoelectric figure of merit (ZT) have been systematically performed. An important increase of electrical conductivity has been observed with increasing filler fraction whereas thermal conductivity only slightly increases, which enhances ZT of several orders of magnitude. Fillers dimension effect is evidenced, but, whatever this dimension, it is shown that, in contrast with thermal conductivity, electrical conductivity follows a percolation behavior through 2D conduction process. This behavior is also observed in the case of the volumetric heat capacity of PANI/RGO nanohybrids which make them potential candidates as high heat capacitive materials. For the first time their heat storage factor is assessed with a new analytical model proposed in this study. The PANI/RGO samples have also been investigated by Dielectric Spectroscopy at different temperatures. Results evidence an interesting charge trapping phenomenon occurring at the PANI/RGO interface which might find promising applications in supercapacitors or gate memory devices.

Book Description
A series of free standing films of doped polypyrrole were prepared and characterized by infrared spectroscopic methods. The frequency dependence of the infrared reflectivity of the polymer films was fit to the Drude model for the dielectric function an electron gas. In order to adequately model the observed reflectance spectra, an additional oscillator term was added to the dielectric function to account for electronic transitions that involve mid gap electronic states. Approximate values for the plasma resonance frequency for these materials range between 1-4 x 10 to the -15th /s, while values for the carrier scattering time were on the order of 10 to the -15/s. The spectral analysis also allowed for the calculation of the complex dielectric constants. These constants appeared to scale with the dc conductivity of the polymer film. It is suggested that the very short carrier scattering time in conducting polymers limits the observed conductivity and that improvements in conducting polymer synthesis and processing techniques will ultimately result in much higher conductivity levels.
