| description |
In this study, aluminium titanate (Al2TiO5) has been prepared by the sol gel method. It
has been intended for use as a ceramic filler in order to investigate how it affects
conductivity and dielectric properties and also the nature of the complexes. Chitosan
has been used as the host with ammonium thiocyanate (NH4SCN) as the salt to supply
the conducting ions. Films of chitosan acetate (CA) , CA-NH4SCN complexes, CAAl2TiO5
complexes and CA-NH4SCN-Al2TiO5 complexes were prepared. The electrical
conductivity of all samples has been calculated using the bulk resistance value obtained
from the complex impedance plot in the frequency range between 50 Hz to 1 MHz. The
film 60 wt.% chitosan – 40 wt.% NH4SCN system exhibits the highest room temperature
electrical conductivity of 1.38 x 10-4 S cm-1. The highest electrical conductivity of the
chitosan-NH4SCN-Al2TiO5 is 2.10 x 10-4 S cm-1 for the film containing 5 wt.% Al2TiO5
at room temperature, 25 oC. The modulus formalism indicates that the samples of
chitosan-based electrolytes are ionic conductors. Infrared (IR) spectroscopy shows the
occurrence of chitosan-salt complexation. X-ray diffraction (XRD) confirms that the
Al2TiO5 filler sample with the highest electrical conductivity is the most amorphous.
This is supported from the result of scanning electron microscopy (SEM). Hence the
effect of Al2TiO4 filler is increment of conductivity and changing the degree of
amorphousness of the highest conducting chitosan-NH4SCN system. |
