“…The resulting composites may effectively combine mechanical properties of the thermoplastic polymer matrix and the electronic properties of PANI to efficiently serve as an active component of an organic gas sensor device [122,123]. Nanostructured PANI-based materials fabricated as nanofibers, core-shell particles, or nanotubes are attractive due to their ability to form thin conductive films with a porous structure [124,125]. The latter morphology enables easy penetration of the analyte molecules inside the sensor film dramatically increasing the detection limit and sensitivity while simultaneously reducing the response time of corresponding sensor devices [126,127].…”

Helium ion microscopy (HIM) is a relatively new high-resolution nanotechnology imaging and nanofabrication tool. HIM offers a near-molecular resolution (approaching that of TEM) combined with a simplicity of sample preparation and high depth of field similar to SEM. Simultaneously, the technique is not limited by the surface roughness as scanning probe microscopy (SPM) techniques or by the surface charging or radiation damage like SEM. In our review, we consider general principles, advantages, and prospects of HIM application in polymer science. Examples of high-resolution imaging of polymer-based nanocomposites, polymer nanoparticles, nanofibers, nanoporous materials, polymer nanocrystals, biopolymers, and polymer-based photovoltaic and sensor devices are presented. We compare the HIM's applicability with other modern imaging techniques: SPM and SEM.

“…Methanol was used as the solvent when doping the polyaniline (PAn) emeraldine base (Sigma Aldrich; Mw ca. 10,000) with p-toluenesulfonic acid (PTSA) to produce the PAn-PTSA [21]. A stock solution of 1.0 × 10 −3 mol L −1 AgNO 3 was prepared with redistilled water and stored in the dark.…”

“…LB films are considered to be more suitable for the fabrication of modified electrodes, as the ordered arrangement of molecules and the nano-scale film thickness are likely to allow both high sensitivity and ultrafast response times [20]. Manigandan et al [21] have produced nanostructured polyaniline using the Langmuir-Blodgett technique, and have used their substrate as an ammonia sensor. As far as we are aware, GC electrode modified by a LB film of polyaniline has never before been used for voltammetric sensing of Ag + .…”

“…8 ppm. In contrast, Manigandan et al, claim the formation of PANI 'rod-like' nanostructures of less than 100 nm in diameter formed by the lateral compression of cation-doped PANI in an LB trough [31]. However, these structures lacked uniformity, order and structural homogeneity.…”

Conducting polymers have been investigated for many years now for their electrical and electrochemical properties. The moderate range of conducting polymers now available, their many derivatives, broad range of counter-ion doping options, level of proton doping, and the many synthetic routes result in a large range of material properties in terms of conductivity, chemical sensitivity, selectivity, and redox characteristics. This allows them to participate in many chemical interactions which are suitable for chemosensing applications.Nanotechnology allows conducting-polymer materials to be studied and applied to chemical sensing in a new way. Controlling the structure and morphology of conducting polymer materials at nanoscales brings the prospect of a range of enhancements not possible with traditional bulk materials. Traditional routes to polymer formation, such as chemical and electrochemical synthesis, lack any fine control on the tertiary structure of the growing polymer, and this lack of structural reproducibility has negative consequences for the performance of the material as a sensor interface. In addition, such polymerizations, Nanostructured Conductive PolymersEdited by Ali Eftekhari
