Conducting polymers have been investigated for many years now for their electrical and electrochemical properties. The moderate range of conducting polymers now available, their many derivatives, broad range of counter-ion doping options, level of proton doping, and the many synthetic routes result in a large range of material properties in terms of conductivity, chemical sensitivity, selectivity, and redox characteristics. This allows them to participate in many chemical interactions which are suitable for chemosensing applications.Nanotechnology allows conducting-polymer materials to be studied and applied to chemical sensing in a new way. Controlling the structure and morphology of conducting polymer materials at nanoscales brings the prospect of a range of enhancements not possible with traditional bulk materials. Traditional routes to polymer formation, such as chemical and electrochemical synthesis, lack any fine control on the tertiary structure of the growing polymer, and this lack of structural reproducibility has negative consequences for the performance of the material as a sensor interface.

Poly(2,5-dimethoxyaniline) (PDMA) has been synthesized by chemical oxidative polymerization technique using varying ratio (wt/wt) of binary oxidants; ferric chloride (FeCl 3 ) and ammonium persulfate (APS). Fourier transform infrared (FT-IR) and ultraviolet-visible (Uv-vis) spectroscopic investigations provide the evidence of the presence of both benzenoid and quinoid ring units. The thermal analysis and structural characterization data suggests that the oxidant ratio greatly controls the molecular ordering in PDMA. Surface morphology shows the existence of both amorphous and crystalline domains wherein the crystalline domain size depends on the oxidant ratio. The dc conductivity (σ dc ) of PDMA is also a function of binary oxidant ratio and at FeCl 3 :APS (50:50), it increases by two orders of magnitude. Films of PDMA synthesized using FeCl 3 :APS (50:50) binary oxidant exhibits a decrease in the surface current on exposure to ammonia gas.
