그래핀 첨가에 따른 신축성 카본전극의 전기적 특성 변화

Translated title of the contribution: The Effect of Graphene on the Electrical Properties of a Stretchable Carbon Electrode

Research output: Contribution to journalArticle

Abstract

Stretchable electrodes are focused due to many demands for soft electronics. One of the candidates, carbonblack composites have advantages of low cost, easy processing and decreasing resistivity in a certain range duringstretching. However, the electrical conductivity of carbon black composites is not enough for electronic devices. Grapheneis 2-dimensional nanostructured carbon based material which shows good electrical properties and flexibility. They mayhelp to improve electrical conductivity of the carbon black composites. In this study, graphene was added to a carbonblack electrode to enhance electrical properties and investigated. Electrical resistivity of graphene added carbon electrodedecreased comparing with that of carbon black electrode because graphene bridged non-contacting carbon black aggregatesto strengthen the conductive network. Also graphene reduced an increase in the resistance of the carbon black electrodeapplied to strain because they connected gap of separated carbon black aggregates and aligned along the stretchingdirection at the same time. In conclusion, an addition of graphene to carbon black gives two benefits on the electricalproperties of carbon black composite as a stretchable electrode.
