Iranian, Azeri Researchers Synthesize Highly Conductive Nanocomposites

TEHRAN (FNA)- The Iranian Researchers in cooperation with their colleagues from the Azerbaijan Republic managed to synthesize highly conductive nanocomposites broadly used in the production of toxic gases' sensors and radar wave absorbing coatings.



According to the Iranian Nanotechnology Initiative council (INIC), Mohammad Reza Saboktakin, an Iranian researcher synthesized the mentioned nanocomposites by a specific chemical method with a desired efficiency.

He enumerated the advantages of this method as the ability of absorbing electromagnetic waves of different frequencies by metallic nanoparticles, the possibility of synthesizing conductive polymers with diverse melting points for which there was no chance of synthesis by the previous methods, placing of metallic nanoparticles into the polymer structure instead of its surface, the chance of using different polymers as carrier polymer and adherence increase, mechanical and thermal resistance of synthesized nanocomposite, and the easy and cheap preparation of raw materials.

Conductive nanocomposites are capable of conducting electric current well owing to the electric charges in their structure. This phenomenon is called 'doping phenomenon'.

Polyaniline, polythiophene, polypyrrole, similar heterocycles and common polymers, which can be used for making conductive nanocomposites, are of the most importance in this research.

Saboktakin stressed that the product has applications in the production of toxic gases' sensors in petroleum, gas, and petrochemical industries, the production of wave absorbing coatings, specially radar wave ones, and the production of conductive coatings etc.

The research was conducted in Arian Chemie Gostar Industrial Research Center, Tabriz, Iran in collaboration with Mohammad Ali Ramazanov and Abel Maharramov from the Nanotechnology Research Center of Baku State University, Azerbaijan.
