Paper Abstract

Electrical impedance properties of bulk carbon nanotube (CNT) composite electrodes have been studied to develop chemical and biosensors. The CNTs embedded in composite electrodes were fabricated by means of traditional film casting and electrospun nanoweb. The morphology of the bulk CNT electrode was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Under the various amounts of buffer solution, electrical impedance of the composite electrodes was measured by means of LCR meter. It is generally known that electrical impedance measurement provides rapid and simple sensing mechanism. In this study, we found out that CNT bulk composite electrodes showed good sensing properties for chemical and bio sensors.
