Surface Area Evaluation of Electrically Conductive Polymer-Based Textiles

Abstract

In this paper, the surface area of coated polymer-based textiles, i.e., copper and nickel plated woven polyester fabric, copper and acrylic coated woven polyester fabric, and copper and acrylic coated non-woven polyamide fabric, is investigated. In order to evaluate the surface area of the woven fabrics, Peirce’s geometrical model of the interlacing point and measurement using an electron microscope are used. Non-woven fabrics are evaluated using an optical method, handmade method, and MATLAB functions. An electrochemical method, based on the measurement of the resistance between two electrodes, is used for relative comparison of the effective surface area of the coated woven and non-woven fabrics. The experimental results show that the measured and calculated warp lengths do not differ within the standard deviation. The model for the surface area evaluation of the Pierce’s geometrical model for monofilament (non-fibrous) yarns is extended to multifilament yarns and to a uniform sample size. The experimental results show the increasing trend of surface area evaluation using both modeling and electrochemical methods, i.e., the surface area of the copper and acrylic coated woven Polyester fabric (PES) is the smallest surface area of investigated samples, followed by the surface area of the copper and acrylic coated non-woven fabric, and by copper and nickel plated woven PES fabric. These methods can be used for surface area evaluation of coated polymer-based textiles in the development of supercapacitors, electrochemical cells, or electrochemical catalysts.

Types of EMG Textile Electrodes: A Comparative Study Using PCA

“…The SPEC electrodes were created using the Ink/Stitch program, which is an embroidery plugin for Inkscape, and then transferred to a computerized knitted textile embroidery machine (Brother670E). The electrodes were created with a stitch length of 1.5 mm, and a conductive, silver-colored polyester fabric made of copper-nickel-plated polyester [14], and stainless steel electro-conductive fabric with a square resistance of 20.3 ohms and 966 GSM were prepared [15]. All the conductive fabrics were developed with a conductive dimensional area of 20 mm × 20 mm, as shown in Figure 2a-c.…”

Design and Smart Textile Materials

“…In a publication detailing their research, Lis Arias et al [11] discussed uncontrolled active molecules in the spraying of textiles and defined polymers that protect active components that permit the regulation of drug dosages, with encouraging results for clothes and in-home use, thereby developing bio-functional textiles. Vojtech et al [12] addressed the problem of identifying a surface area that supports the improved functioning of electrically conductive polymer-based textiles. The researchers employed an electrochemical process to determine the resistance between two electrodes to compare surface areas of textile.…”

“…The researchers employed an electrochemical process to determine the resistance between two electrodes to compare surface areas of textile. ECG measurement and motion tracking were accomplished by developing a new hybrid soft textile electrode [12]. Furthermore, An and Stylios [13] reported that systematic measurements demonstrated that this hybrid textile electrode was capable of recording ECGs and motion signals synchronously, possibly providing a lifechanging approach to constant health monitoring.…”

Highly stretchable conductive fabric using knitted cotton/lycra treated with polypyrrole/silver NPs composites post-treated with PEDOT:PSS

“…Among conductive polymers, polypyrrole (PPy) is one of the most widely used with optimal electrochemical properties, excellent conductivity, simple synthesis process, environmental friendliness, and good chemical and thermal resistance. [2][3][4][5][6][7][8] In situ polymerization is used for developing polymer nanocomposites from nanoparticles. It usually occurs in polymerization mixture and comprises an initiation step, followed by a series of polymerization process, in which a hybrid is formed between polymer molecules and nanoparticles.…”
