“…For future technological applications, these functional groups are determinant for the anchoring of biological material, functionalization with other groups and fabrication of sensing materials. The PPy-NW spectra present the main signals validated with those reported on the literature which confirms the PPy formation [62,63]. A detailed information and data spectra from the Py-silane monomer and the PPy can be found on Fig.S1 and Table S1.…”

Abstract:Highly efficient nano-engineering tools will certainly revolutionize the biomedical and sensing devices research and development in the years to come. Here, we present a novel high performance conducting poly(pyrrole) nanowires (PPy-NW) patterning technology on thermoplastic surfaces (poly(ethylene terephthalate (PETE), poly(ethylene 2,6-naphthalate (PEN), polyimide (PI), and cyclic olefin copolymer (COC)) using nanocontact printing and controlled chemical polymerization (nCP-CCP) technique. The technique uses a commercial compact disk (CD) as a template to produce nanopatterned polydimethylsiloxane (PDMS) stamps. The PDMS nanopatterned stamp was applied to print the PPy-NWs and the developed technology of nCP-CCP produced 3D conducting nanostructures. This new and very promising nanopatterning technology was achieved in a single step and with a low cost of fabrication over large areas.

“…However, the latter range is not identical with spectra in the literature, which may indicate that lower (Avlyanov et al 1997). No precise location of the PPy absorption band is observed either, as it is broad and lies within the 900-1100 cm -1 range (Manik et al 2011). Microbiological activity of fabrics with deposited carbon nanotubes and silver nanoparticles electrochemically deposited on their surface was tested by a qualitative method.…”

The paper presents results of tests on the possibility of utilising fabric with a deposited spatial network of multiwall carbon nanotubes (MWCNTs) as electrodes in processes of their functionalization by electrochemical methods enabling deposition of metal nanoparticles, as well as-by electropolymerizationof conductive polymer nanocoatings. Cyclic voltammetry was employed in the testing, which was used to functionalise various types of fabrics covered with a MWCNT spatial network by depositing silver nanoparticles and polypyrrole (PPy) nanocoating, conferring bioactive properties and significantly increased specific capacity, respectively, to the layered hybrid textile materials acquired this way.

“…A significant difference in FTIR identities between the precursor and the final product occurs within the region from 500 to 1,500 cm -1 wavenumber, where a symmetric and anti-symmetric ring-stretching vibrations of C=C bond at 1,540 and 1,454 cm -1 , 1,149 cm -1 vibration of pyrrole ring (disappear for N-doped carbon), 1,033 cm -1 in plane C-H and N-H deformations are present. Also the peak near 1,000 cm -1 attributes to C-N stretching is weaker for carbonized material [22].…”

Nitrogen-doped carbon is a promising metalfree catalyst for oxygen reduction reaction in fuel cells and metal-air batteries. However, its practical application necessitates a significant cost reduction, which can be achieved in part by using new synthetic methods and improvement of catalytic activity by increasing the density of redox active centers. This can be modulated by using polymer as the carbon and nitrogen sources. Although, superior catalytic activity of such N-doped C has been investigated in details, the electrochemical long-term stability of polymer-derived doped-carbon is still unclear. Herein, in this study we generated N-doped carbon from the most recommended polymer that is comparable to the state-of-the-art materials with porosity as high as 2,086 m 2 g -1 and a nitrogen doping level of 3-4 at.%, of which 56 % is pyrrolic N, 36.1 % pyridinic and *8 % graphitic. The electrochemical characterization shows that N-doped carbon is catalytic toward oxygen reduction in an alkaline electrolyte via a favorable four-electron process, however, not stable under long-term potential scanning. The irreversible electrochemical oxidation of this material is associated with the presence of a significant content or pyrrolic and pyridinic N close to the edge of the carbon network originating from the polypyrrole precursor. These structures are less stable under operating electrochemical potential. The role of polypyrrole as the precursor of N-doped carbons has to be carefully revised since it supplies sufficient number of catalytic sites, but also generates unstable functionalities on the carbon surface.
