By Meixiang Wan
Conducting Polymers with Micro or Nanometer Structure describes a subject found via 3 winners of the Nobel Prize in Chemistry in 2000: Alan J. Heeger, collage of California at Santa Barbara, Alan G. MacDiarmid on the collage of Pennsylvania, and Hideki Shirakawa on the collage of Tsukuba. considering then, the original houses of carrying out polymers have ended in promising functions in useful fabrics and applied sciences. The e-book first in short summarizes the most strategies of engaging in polymers sooner than introducing micro/nanostructured carrying out polymers facing their synthesis, structural characterizations, formation mechanisms, actual and chemical houses, and strength functions in nanomaterials and nanotechnology. The booklet is meant for researchers within the comparable fields of chemistry, physics, fabrics, nanomaterials and nanodevices. Meixiang Wan is a professor on the Institute of Chemistry, chinese language Academy of Sciences, Beijing.

These indicated that the protonation process only takes place on the imine segment of the emeraldine chain, which was also consistent with Huang’s suggestion [4]. That was also conformed by fluorescence excitation and emission spectra of PANI [14]. It noted that the intensity of peaks at 630 and 950 nm are strongly affected by the protonation state [15]. As shown in Fig. e. g. at pH 2 6), indicating the quinoid segment on the polyemeraldine chain is present in partially protonated PANI. Based on above results, author modified the general molecular formula of PANI by adding a parameter of the protonation state (x) as shown in Fig.
As shown in Fig. 2, the proton doping dose not involve a change of the number 17 Conducting Polymers with Micro or Nanometer Structure of electrons associated with the polymer backbone during the proton doping [4, 7b]. g. oxidation or deduction) where involves the partial addition (reduction) or removal (oxidation) of electrons to or from the polymer backbone [9]. Thus proton doping is major characteristics of PANI differing from other conducting polymers. 2 Scheme of proton doping in PANI [6] In principle, the imine nitrogen atom on the polymeric chain of PANI can be protonated in whole or in part to obtain the corresponding salts and the protonation degree on the polymeric base, depending on its oxidation state and the pH value of the aqueous acid [4].
