Conductive polymers: a route for sustainability

Abstract [en]

The concept of sustainable use of materials defines as utilizing raw material as less as possible and introducing less toxic substances to the environment as well. Smart materials are one route for sustainability, as they have optimal performance in relation to material composition. New technologies can be developed by using smart materials. One area is the development of smart textiles, meaning the incorporation of electronic functions in textiles. These functions can be used for human protection or monitoring of health.Conductivity is a key factor in smart textiles. The aim of this report is to identify electrically conductivity of textile fibres in conjunction with conductive polymer (polyaniline). By applying conductive polymer (polyaniline ink) on textiles fabric and fibres it is possible to obtain conductive textile products. This project focuses on the development of conductive fibres by coating of an individual fibre or a few different types of fabric with conductive polymer polyaniline dispersion in water and toluene as solvent. Various situations have been taken into consideration and investigated for different concentration to different times of coating and deposit thickness. Performance on resistivity calculation led to find optimum concentration and coating numbers and deposit thickness. Based on the inventory, a qualitative resistivity analysis is carried out for the purpose of identifying which combination of concentration and times of coating in the case of woven types fibre or coating thickness in the case of non woven types of fabrics as well as the types of fabrics would provide the better conductivity properties in the textile fibres and fabrics.
