“…The results show that maximum increase in conductivity occurred at 10 wt%, after which the conductivity started to decrease. It is believed that further increase in the percentage of inorganic precipitate hinders the carrier transport between conjugated chains of PANI (Su and Kuramoto 2000;Xu et al 2005) that leads to decrease in the overall conductivity.…”

This present paper reports the synthesis and environmental applications of conducting polyanilineSn(IV)tungstomolybdate nanocomposite. The material was synthesized via a very simple chemical route and characterized by using various instrumental techniques. Physicochemical properties, pH titrations, and elution behavior were studied to exploit the ion-exchange capability of nanocomposite. Electrical conducting studies were performed by using 4-in-line-probe (Direct Current) electrical conductivity measuring instrument. The conductivity of the material was found to be in the range of semiconductor's. Distribution coefficient values were measured in demineralized water and varying concentration of dimethyl sulfoxide, and on the basis of partition coefficient values, the material was found to be selective for Pb 2? ions. This nanocomposite material has been fruitfully applied for the treatment of heavy metals from synthetic mixture and industrial waste water samples. The limit of detection and the limit of quantification for Pb 2? ion were found to be 0.97 and 3.24 lg L -1 , respectively. The material was also tested for antimicrobial activity, and it was found that besides its use as an ion-exchange material, polyaniline-Sn(IV)tungstomolybdate is successfully used as an antimicrobial agent and as well as semiconductor.

“…Xu et al [117] noticed that the electrical conductivity of a polyaniline-TiO 2 nanocomposite with a low TiO 2 content is much higher than of polyaniline. Su et al [118] reported that the polyaniline-TiO 2 nanocomposite has suitable conductivity (1-10 S/cm) and increases after thermal treatment at 80°C for 1h. Due to moderate conductivity and high dielectric losses, these polymer composites found its application as microwave absorber.…”
