| Summary: | Stable colloidal suspension of magnetite/starch nanocomposite was prepared by a facile and aqueous-based
chemical precipitation method. Magnetite/carbon nanocomposite thin films were subsequently formed upon
carbonization of the starch component by heat treatment under controlled conditions. The initial content of
native sago starch as the carbon source was found to affect the microstructure and electrochemical properties
of the resulted magnetite/carbon nanocomposite thin films. A specific capacitance of 124 F/g was achieved
for the magnetite/carbon nanocomposite thin films as compared to that of 82 F/g for pure magnetite thin
films in Na2SO4 aqueous electrolyte |
