ABSTRACT
This chapter discusses the application of different types of electrochemically prepared electrically conducting polymers (ECP)-carbon nanotubes (CNT) and ECP-graphene composites in electrochemical sensing. In the field of electrochemical sensors, there is a continuous need for new electrode materials. The possibility of precisely directing the electrodeposition of the composite materials on small well-defined electrically conducting surfaces is an advantage in solid-state electrochemical sensing applications. Chemical or electrochemical polymerization methods can be used for the fabrication of ECP-CNT composites. The determination of nitrite using electrochemical methods offers simple, inexpensive, and faster analysis method compared to some other more expensive and time-consuming techniques such as chromatography or spectrophotometry. The combination of ECPs and the carbon nanomaterials is greatly expected to contribute to the development of new composites with complementary properties and utilize the synergistic effect arising from the non-electrostatic interactions of their conjugated structures.
