“…The methods used to incorporate conductive materials with the fibres or yarns needs sophisticated processes and/or equipment which compromises large scale production. In contrast, process complications can be reduced considerably by incorporating conductive materials directly onto preformed textiles fabrics using polymerisation, deposition of metals, weaving or integration of metal fibres or wires [1,13,[15][16][17][18][19][20][21].…”

A cost effective electrically conductive textile for large scale applications would revolutionise numerous industries. Herein, we demonstrate a novel processing approach to produce conductive textiles for industrial applications. A conductive nonwoven textile was successfully fabricated using a simple dip coating method. The nonwoven polyester was coated with liquid crystallite graphene oxide with subsequent non-toxic chemical reduction. The process is readily scalable. The graphene coated fabric has been characterized by electron microscopy as well as by electrical, mechanical, thermal and abrasion resistance measurements. It was found that the electrical surface resistivity of the prepared polyester-graphene composite fabric was 330 Ω □-1. The electrical surface resistivity was 3 and 150 times lower than that of polypyrrole coated woven polyester fabric and graphene coated nonwoven fabrics, respectively, in previously published reports. The hybrid polyester-graphene textile prepared here should find applications in high-performance geotextiles or as heating elements.

“…The coating thickness and its variation with monomer concentration have been reported by the authors in a previous publication. 4 The mean thickness of the polypyrrole coating on polyethyleneterephthalate (PET) fibers was determined by the optical fiber diameter analyzer (OFDA), which measures the width of at least 20,000 individual fibers from each sample by use of a projection microscope and a digital camera. The diameters of both polypyrrole-coated fibers and uncoated fibers were determined, and the mean thickness of polypyrrole layer was calculated by the difference in radius.…”

“…3 This was followed by a report on the alteration of surface resistivity in conducting polypyrrole-coated polyester fabrics by controlling the thickness of the conducting polymer film through adjusting the reaction parameters and the monomer concentration. 4 Surface resistivity changed as the thickness of the coating layer varied from 0.2 to 0.6 m. The concentration of about 0.4 mg/mL indicated a critical point for the monomer consumption on the surface of the textile. Above this concentration the rate of increase of coating thickness decreased and polymerization in solution was observed.…”

Heating effects in polypyrrole-coated polyethyleneterephthalate (PET)-LycraR fabrics were studied. Chemical synthesis was employed to coat the PET fabrics by polypyrrole using ferric chloride as oxidant and antraquinone-2-sulfonic acid (AQSA) and naphthalene sulfonic acid (NSA) as dopants. The coated fabrics exhibited reasonable electrical stability, possessed high electrical conductivity, and were effective in heat generation. Surface resistance of polypyrrole-coated fabrics ranged from approximately 150 to 500 /square. Different connections between conductive fabrics and the power source were examined. When subjected to a constant voltage of 24 V, the current transmitted through the fabric decreased about 10% in 72 h. An increase in resistance of conductive fabrics subjected to constant voltage was observed. C 2005 Wiley Periodicals, Inc.

Preparation of conductive cotton fabrics, by polymerization of pyrrole in presence of FeCl 3 as an oxidizing agent and tetraethylammonium p-toluene sulfonat (TEAp-TS) as a doping agent which in turn caused a reduction in the moisture regain of the substrate, resulted in production conductive cotton fabrics in laboratory scale. Factors affecting the properties of the fabrics were studied, such as ratio between FeCl 3 and TEAp-TS and pyrrole concentration. Polypyrrole coated cotton fabrics were characterized by scanning electron microscopy (SEM) and Fourier transform-infrared (FT-IR) spectroscopy. Resistivity, weight gain, color strength, tensile strength and elongation of the coated fabric with polypyrrol were monitored according to ASTM procedures. The results had shown that, the conductivity, weight gain, color strength, tensile strength and elongation increase by increasing FeCl 3 , TEAp-TS and pyrrole concentration. This is due to the increase of amount of the conductive polymer on the fabric surface.
