Abstract

Polydimethylsiloxane (PDMS) is one of the most used materials in bio-applications. However, previous works were mainly focused on mechanical aspects. In this paper we presented a practical and efficient approach to enhance the electrical properties of PDMS by using conducting polymer nanowires (CPNWs). The nanowires were synthesized using the template method and added in PDMS to form nanocomposites. The dielectric constants of the composites were characterized by impedance measurements. The dielectric relaxation behavior and the volume fraction of CPNWs were investigated. Based on the percolation theory a much lower threshold (5.3 vol.%) was achieved.
