“…[65] A variety of functional dopants, most of them sulfonated, can be used to produce anisotropic nanostructures of PAni. These dopants can also include C 60 -SO 3 H or CNT-SO 3 H. [72,73] These particular dopants have been suggested to form salts with aniline thereby acting as a template for the formation of PAni nanostructures much the same way that surfactant micelles act as templates for mesoporous materials. An interesting group of dopants used for this purpose are amphiphilic azo-benzene sulfonate [74] or C 3 ABSA.…”

This Progress Report provides a brief overview of current research activities in the field of one‐dimensional (1D) conducting polymer nanostructures. The synthesis, properties, and applications of these materials are outlined with a strong emphasis on recent literature examples. Chemical methods that can produce 1D nanostructures in bulk quantities are discussed in the context of two different strategies: 1) procedures that rely on a nanoscale template or additive not inherent to the polymer and 2) those that do not. The different sub‐classifications of these two strategies are delineated and the virtues and vices of each area are discussed. Following this discussion is an outline of the properties and applications of 1D conducting polymer nanostructures. This section focuses on applications in which nanostructured conducting polymers are clearly advantageous over their conventional counterparts. We conclude with our perspective on the main challenges and future research directions for this new class of nanomaterials. This Progress Report is not intended as a comprehensive review of the field, but rather a summary of select contributions that we feel will provide the reader with a strong basis for further investigation into this fast emerging field.

“…In addition, obvious aggregation of the MWNTs occurred in acidic conditions in the absence of CSA, in contrast with MWNTs in the presence of CSA alone. This indicates that CSA not only plays both roles of a chiral inducing agent and a dopant, but also serves as a surfactant [11] simultaneously keeping the MWNTs from aggregation.…”

Optically active polyaniline–carbon‐nanotube nanocomposites are synthesized by using a solution‐chemistry method. The stereochemical selectivity of the composites can be tailored by controlling the nanotube loading. At low nanotube contents (<3 wt %), the chiral composites show high absolute stereochemical selectivity. The figure shows normalized circular dichroism spectra of the composites with different nanotube/monomer weight ratios in aqueous solutions.

“…Then we consider that the formation of such structure is similar with that of PPy or PANI sub-micrometer-sized tube junctions and dendrites through self-assembly. The micelles can aggregate to form branched structures, which act as templates for sub-micrometer-sized tube junctions and dendrites [21]. Meanwhile, we find this dentritic structure appears to be steady, which keeps the PPy from precipitation.…”

Polypyrrole (PPy) dispersion was prepared using FeCl 3 ·6H 2 O as oxidant in the presence of sodium dodecylbenzenesulfonate (SDBS) as surfactant. The formation of the micelles and the electrostatic interaction between PPy and SDBS were considered the driving forces for the formation and stability of the dispersion. UV/Vis/NIR, FTIR spectra and SEM images were studied to confirm the structure and morphology of the PPy dispersion, respectively. Polymerization of pyrrole under different preparation conditions including the concentration of the surfactant, the pyrrole monomer and the oxidant and also the addition of acid were carried out in order to investigate their effects on the stability and average particle size of the dispersions. The conductivity of the resulting PPy particles was measured and a comparison between the PPy and polyaniline dispersion formed with SDBS as surfactant was also given.
