high Performance Textile supercapacitor electrode materials enhanced with three dimensional carbon nanotubes graphene conductive network and in situ polymerized polyaniline
Electrochimica Acta, 2017Co-Authors: Fu Shao, Jianan Zhang, Shaowei BianAbstract:Abstract Three-dimension (3D) conductive network was successfully constructed by carbon nanotubes (CNTs) and graphene sheets (G) on the polyester fabric (PETC) using a “dipping-drying” process and electrophoretic deposition method, which facilitates to greatly enhance the electron transportation rate and shorten the electrolyte ion diffusion distance. The resultant composite fabric provides a promising substrate to prepare Textile-based electrodes for flexile supercapacitors. After further coating the CNTs with polyaniline (PANI), the polyaniline/carbon nanotubes/graphene/polyester (PANI/CNTs/G/PETC) Textile electrode exhibited high electrochemical Performances. The composite electrode showed a maximum areal capacitance of 791 mF cm −2 at a current density of 1.5 mA cm −2 . Compared to some reported PANI electrodes with fast decay in capacitance capacity, the capacitance retentions of the composite electrode was over 76% even after 3000 charge-discharge cycles. Moreover, the composite electrode also exhibited stable electrochemical Performances under the mechanical bending and stretching conditions.

Oxidative in situ deposition of conductive PEDOT:PTSA on Textile substrates and their application as Textile heating element
Synthetic Metals, 2012Co-Authors: Klaus Opwis, Dierk Knittel, Jens Steffen Ralf GutmannAbstract:Abstract Conductive organic polymers are outstanding materials with exciting properties. Besides several other applications – especially in the field of high-Performance electric devices and photovoltaic technology – they can be used for the creation of conductive Textile materials. Commercial dispersions of such polymers can be applied to Textile constructions in a downstream coating process leading to poor add-ons and relatively low conductivity. In contrast, the authors have developed strategies to deposit conductive polymers by an oxidative in situ polymerization directly on the Textile surface. Here, poly(3,4-ethylene dioxythiophene) p -toluenesulfonic acid (PEDOT:PTSA) was durably immobilized on a Textile polyester fleece following this new approach. The extremely high achievable add-ons lead to extraordinary high-conductive Textiles with surface resistances down to 10 Ω/sq. Such a way finished Textiles can be used as high-Performance Textile heating elements. For example, by applying a standard voltage of 24 V temperatures up to 170 °C are practicable. Moreover, the desired temperature is easily adjustable by the absolute load and the applied voltage. These conductive Textiles can be used, e.g., in carpets, electric blankets or automotive seat heaters.

Potentiality of utilising natural Textile materials for engineering composites applications
Materials and Design, 2014Co-Authors: Mohd Iqbal Misnon, Md Mainul Islam, Jayantha Ananda Epaarachchi, Kin-tak LauAbstract:This paper gives an overview of utilising natural Textile materials as reinforcements for engineering composites applications. The definition and types of Textile materials are addressed to provide readers a thoughtful view on the role of these materials in a structural composite system. Available material properties of natural Textile and their composites are critically reviewed here. In general, these materials are categorised into fibre, yarn and fabric forms. The load bearing capacity of natural Textile fibre reinforced polymer composites is governed by the quantity, alignment and dispersion properties of fibres. It has been found that the natural fibre reinforced composites are limited to use in low to medium load bearing applications. However, a limited research work has been performed to date and there is a significant gap between the high Performance Textile fabric and their use as reinforcement in fibre reinforced composite materials. © 2014 Elsevier Ltd.
