Effect of incorporation of maghemite nanoparticles and graphite in chitosan films.

In this research effect of incorporation of maghemite nanoparticles and graphite in chitosan membranes is studied using dielectric spectroscopy technique. Graphite was used as it has high electrical conductivity and is affordable. It is observed that the dielectric constant, dielectric loss, dissipation factor and conductivity are affected due to the presence of graphite and maghemite in the nanocomposite films. The films were made using solution casting technique. The conductivity increased when maghemite nanoparticles were included in the nanocomposites. This research could benefit battery technology and microelectronics. [ABSTRACT FROM AUTHOR]
