Smart textiles are defined as textileproducts such as fibres, filaments, yarns or fabrics etc. have active functionsproviding an interaction with the environment/user together with traditionaltextile properties. One of the functional smart textile products are electronictextiles or wearable electronics which its application is vast in differentfields and its benefits attract most of the researches concerns. Despite ofsuch signi?cant advancements, there is still need of stretchable, flexible andcomfortable wearable electronics having electronic functions. Among varioustypes of wearable electronics, fiber-based conductive materials are ideal forwearable electronics due to their light, durable, ?exible, foldable andcomfortable structure. Conductive fibrous materials are obtained by conductivepolymer, metal, carbon, piezoelectric materials, or conventional ?bers surfacemodi?ed with various functional materials. Among various carbon materials,graphene, carbon nanotubes, and carbon black are the most intensively exploredcarbon allotropes in materials science and have been well researched asalternatives to conventional materials, such as conductive polymers andmetallic nanomaterials used in flexible electronics. In this study, it is aimedto obtain flexible and conductive fibrous structure by electrospinning methodthrough the addition of synergistic carbon black (CB) and graphene bifillers topolyurethane matrix. The combination of two type conductive fillers ispreferred to construct distinct conductive network morphology on the basis ofsynergistic effect compared with the sensing behaviour of single filler. In thestudy, morphological and chemical properties of electrospun compositenanofibers are evaluated by SEM and FT-IR, respectively. Additionally,electrical properties of the samples are measured by two-point analysis methodusing Fluke instrument and resistance values are obtained. Fibrous conductivecomposite structures produced as in this study may find usage areas such ashuman motion detection, communication facilities, data transfer, robotics andmany other applications.<o:p></o:p></span></p> |
