Carbon nanotubes -based electrochemical electrode preparation

Electronically conducting polymers (ECPs) such as polyaniline (PANI), polypyrrole (PPy) and po 1 y(3.4-cthy 1 cncdi oxyth iophcnc) (PEDOT) have been applied in supercapacitors, due to their excellent electrochemical properties and lower cost than other ECPs. We demonstrated that multi-walled carbon nanotubes (CNTs) prepared by catalytic decomposition of acetylene in a solid solution are very effective conductivity additives in composite materials based on ECPs. In this paper, we show that a successful application of ECPs in supercapacitor technologies could be possible only in an asymmetric configuration, i.e. with electrodes of different nature. 

Another recent topic in detection of OP compounds based on ChE-modified biosensors is to use carbon nanotubes (CNTs) as an electrode modifier. CNTs are known to exhibit excellent electrochemical properties originating from high catalytic activity of edge-plane-like graphite sites at CNT ends and a large effective surface area. Lin et al. (2004) have reported that stable CNT-modified glassy carbon (GC) electrodes can be prepared by coating the surface of GC electrode with a suspension of CNT and can be used for sensitive determination of thiocholine (Liu etal,...
