Preparation and characterization of polynaphthyl amine (PNA) as a novel conducting polymer

A series of polynaphthyl amine (PNA) were prepared in acetone/water mixture (v/v) using different concentrations of potassium persulfate as an initiator in presence and in absence of polyvinyl alcohol (PVA) as a surface active agent. Polymers of various physical properties were prepared. The physical properties of PNA using different concentrations of potassium persulfate in presence and in absence of PVA were given. The specific conductance of the prepared polymers was found to be 0.055 ohm cm, 0.145 ohm−1 cm−1 and 0.083 ohm−1 cm−1, at 3, 1.5, and 0.75% of potassium persulfate, respectively. X-ray diffraction analysis was carried out to the sample having the highest specific conductance. The confirmation of the prepared PNA was carried out using UV and IR spectrophotometry. Finally PNA showed good air stability and excellent solubility in organic solvents differing from that of polyaniline.
