“…The conducting polymers are conjugated macromolecules that exhibit electrical and optical property changes when they are protonated/deprotonated by certain chemical agents. In recent years, conducting polymers, such as polypyrrole and polyaniline (PANI), have been proposed as chemical sensors based on the changes in their electric conductivity when they are exposed to ammonia (Agbor et al, 1995;Brie et al, 1996;Koul & Chandra, 2005).…”

“…The importance of environmental gas monitoring is well understood, and many studies have focused on the development of suitable gas-sensing materials [1]. The toxic gases generated in many places such as plants and laboratories cause adverse effects on the human body and generate acidic rain, which devastates the environment.…”

Conducting polymer-coated multiwalled carbon nanotubes (MWCNTs) were prepared by template polymerization in order to enhance their gas sensitivity. This investigation of the conducting polymer phases that formed on the surface of the MWCNTs is based on field-emission scanning electron microscopy images. The thermal stability of the conducting polymer-coated MWCNTs was significantly improved by the high thermal stability of MWCNTs. The synergistic effects of the conducting polymer-coated MWCNTs improve the gas-sensing properties. MWCNTs coated with polyaniline uniformly show outstanding improvement in gas sensitivity to NH 3 due to the synergistic combination of efficient adsorption of NH 3 gas and variation in the conduction of electrons.

“…Grafting with other polymers having good mechanical and physical properties is one of them. Many potential applications of PAni are demonstrated recently [2,[5][6][7]. The polymers should be insoluble in whole range of pH to gain some of the applications.…”

Polyaniline as a conductive polymer and chitosan as a natural polymer have been reacted with formaldehyde as grafting agent and potassium persulfate as an initiator. The effect of using specific primer, different ratio of monomers and the solubility of synthesized copolymer has been studied and analyzed. Characterization of this new copolymer were occurred by Fourier transform infrared spectroscopy, UV-visible, scanning electron microscopy and differential scanning calorimetry technique.
