“…From the above observations, it appears that the Ag + ion first coordinated with the N atom of PAn [26], and was then reduced to Ag 0 during the preconcentration step. Ag 0 was oxidized to Ag + during the stripping step.…”

“…The second weight loss step at around 320 ℃ is related to the removal of dopants and the loss of low molecular weight oligomers or side products (hydroquinone or quinone) [20,21]. It can be observed that the third mass lose takes place at about 400 ℃, which is corresponding to the degradation and decomposition of the backbone units of PAn [22,23].…”

“…The shape and size of the nanofibers does not appear to be affected by the solvent. PANI-NFs were prepared by an interfacial method in the presence of HCl [135,[143][144][145][146][147][148][149][150], HCl and SDS [151], HClO 4 [152][153][154], CSA [53], poly(styrenesulfonic acid) (PSSA) [155,156], DL-tartaric acid [157], DBSA [158], p-TSA [159], cerium(IV) oxide nanoparticles [160], and magnesium carbonate particles [161]. is preferred due to safety considerations, since the water layer seals the organic vapor within the reaction vessel.…”

“…is preferred due to safety considerations, since the water layer seals the organic vapor within the reaction vessel. Ag nanoparticle/PANI-NF and Pt nanoparticle/PANI-NF nanocomposites were generated by the interfacial oxidative polymerization of aniline with silver methanesulfonate and hexachloroplatinic acid, respectively [149]. The major disadvantages of interfacial polymerization are low synthetic yields (6-10 wt %) and the waste stream of organic solvents that must be treated.…”

Polyaniline (PANI) is one of the most extensively studied conducting polymers because of its simple synthesis [1] and doping/dedoping chemistry [2], low cost, high conductivity, and excellent environmental stability. PANI has a wide applicability in rechargeable batteries [3], erasable optical information storage [4], shielding of electromagnetic interference [5], microwave-and radar-absorbing materials [6], sensors [7], indicators [8], catalysts [9], electronic and bioelectronic components [10], membranes [11], electrochemical capacitors [12], electrochromic devices [13], nonlinear optical [14] and light-emitting devices [15], electromechanical actuators [16], antistatic [17] and anticorrosion coatings [18]. Its electromagnetic and optical properties depend mostly on its oxidation state and degree of protonation [19]. The green emeraldine salt form of PANI is conducting ($1-10 S cm À1 for granular powders) [1]. It contains, depending on the synthetic route, variousunits (in the preceeding formulae B, Q and A À denote a benzenoid ring, quinonoid ring and dopant anion, respectively). The blue emer-The preparation of bulk quantities of conducting granular PANI is usually performed Nanostructured Conductive PolymersEdited by Ali Eftekhari by the oxidative polymerization of aniline with ammonium peroxydisulfate (APS) in an acidic aqueous solution (initial pH < 2.0) [1]. Colloidal PANI nanoparticles are prepared by dispersion polymerization of aniline in the presence of various colloidal stabilizers [20,21]. The average size of colloidal PANI nanoparticles decreases with increasing stabilizer/aniline ratio. PANI colloids often have nonspherical (rice grain, needle-like, etc.) core-shell morphology. The colloidal nanoparticle core most likely has a composite nature, i.e. it is composed of both the PANI and the incorporated stabilizer, while the shell is formed by the stabilizer. Nowadays, conducting PANI nanostructures are the focus of intense research owing to their significantly enhanced dispersibility and processability, and substantially improved performance in many applications, in comparison with granular and colloidal PANI [22][23][24][25][26][27]. The continuously growing interest in the study of zero-dimensional (0-D) (solid nanospheres), one-dimensional (1-D) (nanofibers (nanowires), nanorods (nanosticks), nanoneedles, rice-like nanostructures, nanotubes), two-dimensional (2-D) (nanoribbons (nanobelts), nanosheets (nanoplates, nanoflakes, nanodisks, leaf-like nanostructures), nanorings (cyclic nanostructures), net-like nanostructures), and three-dimensional (3-D) PANI nanostructures (hollow nanospheres, dendritic and polyhedral nanoparticles, flower-like, rhizoid-like, brain-like, urchin-like, and star-like nanostructures, etc.) has dramatically increased in recent years (Figure 2.1). The major focus of research has been the preparation, characterization, processing, and application of PANI nanofibers (PANI-NFs) and nanotubes (PANI-NTs). PANI-NFs are 1-D PANI nanoobjects of cylindrical profile with diameters ...
