An Integrated Use of Biopolymer-Ceramic Composites Towards Capacitor and Environmental Application

摘要

Biopolymer composite films comprising strontium titanate crystallites in ((100-x) Cellulose-xSrTiO3 (0 < x < 90, in wt ) system were fabricated via solution casting technique. The X-ray diffraction (XRD) and scanning electron microscopic (SEM) studies were carried out on these composite films for structural and micro-structural analyses. The dielectric constant of these composites increased with the concentration of strontium titanate crystallites dispersed in the cellulose matrix. Different dielectric mixture formulae were employed to rationalize the dielectric properties of the biopolymer composite systems. The composite films also showed promising application towards the removal of toxic chromium(VI).
