Conducting terpolymers and its hybrid nanocomposites variable trends. From synthesis to applications. A review

This review aimed to provide a trend and evolution on the methods of conducting terpolymer synthesis and its applications for the first time in the open literature. Lots of attention was on homopolymer and copolymer in the onset of research on conducting polymers, but quest for improved optical, electrochemical, and conductive properties borne research in conducting terpolymerization. It comes with advantages of mass production of the polymeric film but has its limitation in film thickness control and its low conductivity. Lately, conducting polymer synthesis research over the years has evolved and electrochemical methods have been the favorite method of synthesis as it offers improved properties for the polymeric film. Terpolymers, over the years have been applied for various applications in electrochemical bio-sensing, corrosion inhibitors and polymeric solar cells. However, there is still need for enlarge scope of terpolymer synthesis to involve polymerization of carboxylic acid monomers, incorporation of biopolymers, as most reported conducting terpolymers over the years have been largely based on aniline and its hybrid monomers. Also, it is recommended that pursuit of conducting terpolymers as a nonenzymatic electrochemical and biosensors should be intensified and given increased attention.
