Changes in the conducting and hydrophilic properties of composites MF-4SC/polyaniline (PAni) under conditions of prolonged synthesis have been studied. A maximum of PAni content of about 0.20 by weight, which can be incorporated into the matrix of MF-4SC under these conditions of synthesis, is determined. Percolation behavior of electrical conductivity of the composites after drying was observed. The conductivity of PAni salt inside MF-4SC was estimated within the frames of the percolation model. Using the fibrous cluster model of the membrane and the conductivity data on individual PAni, theoretical assessment of the electrical conductivity of nanocomposite MF-4SC/PAni has been performed. Reasons for a significant reduction in the conductivity of PAni during its integration into the structure of the initial matrix were discussed. A scale of membrane conductivity, reflecting changes in the electrical conductivity of composites at various stages of synthesis, was drawn.

“…Fabrication of CPs at the nanoscale-level can be realized through template synthesis and post-assembly methods 6,7 as well as with use of photo-and soft lithography. 8,9 Template synthesis 45 leads to formation of many kinds of discrete CP nanostructures but precisely controlling their position, for example as part of well-defined electrode array, is challenging.…”

Due to the current interest in organic printable electronics, Dip-Pen Nanolithography (DPN) is increasingly being explored as a method to pattern electroactive materials such as conducting polymers (CPs) on the micro-and nanoscale. In general, printing process depends strongly on the ink-substrate properties and fundamental forces required to drive and stabilize the ink transfer to the substrate. Controlling these parameters is especially difficult when operating under the nanometer confinements of the DPN probe. For the printing of CPs, one step towards addressing these challenges is rational ink design, as the use of existing commercial-based inks may not be suitable for the DPN ink transfer process on the nanoscale. Due the current interest in organic printable electronics, Dip-Pen Nanolithography (DPN) is increasingly being explored as a method to pattern electromaterials such as conducting polymers (CPs) on the microand nanoscale. In general, printing process depends strongly on the ink-substrate properties and fundamental forces required to energetically drive and stabilize the ink transfer to the substrate. 10Controlling these parameters is especially difficult when operating under the nanometer confinements of the DPN probe. For the printing of CPs, one step toward addressing these challenges is rational ink design, as the use of existing commercial-based inks may not be suitable for the DPN ink transfer process on the nanoscale. In this study, we synthesized and developed a poly(3,4 ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS)-based ink, to which we could add known constituents for 15 optimizing the printing, adhesive and conductive properties of an aqueous dispersed ink. For silicon and gold surfaces, we demonstrate that the DPN pattering of the ink could achieve PEDOT:PSS (dot) arrays with diameters ranging from the submicron down to ~160 nm. These dimensions represent a dramatic improvement in resolution compared to previous attempts in patterning of CP via physioadsorption process using DPN. This work highlights that rational design of CP inks is critical, especially for DPN 20 where the ink transfer process is governed by fluid physical properties and surface forces in the nanodomain. Knowledge of the constituents and overall ink composition will also lead to a greater understanding of these fundamentals that facilitate the pattering of CP inks on the nanoscale using DPN.

“…Anodic aluminum oxide (AAO) and particle track-etched membranes (PTM) have been widely applied with good controllability to produce CP nanowires/tubes [14,[45][46][47]. The diameters of PTMs pores can be as small as 10 nm and the density of pores ranges from 10 5 to 10 9 pores per cm 2 [40]. Many NCPs such as PANI [45,47], PPy [48,49], PEDOT [50,51], have been chemically or electrochemically synthesized in the form of nanowires or nanotubes by different membranes.…”
