Using Unbleached Bagasse Fibers for Fabricating Magnetic Paper

Magnetic lignocellulosic fibers have good potential in applications such as information storage, security papers, electromagnetic shielding and etc. In this study unbleached bagasse fibers were used to fabricate magnetic paper by chemical co-precipitation method. Lumen loading and precipitation of magnetic nanoparticles on the surface of fibers were carried out by in situ synthesis. Then the formation of magnetite and hematite nanoparticles during synthesis process was demonstrated by patterns of X-ray diffraction (XRD). Micrographs of scanning electron microscopy (SEM) indicated well the nanoparticles deposition on the fiber surfaces. Degree of loading increased with increasing temperature up to 60 ̊C and iron content of suspension up to 6mmol. The magnetic particles deposited on the fiber surfaces had detrimental effects on the tensile strength of the magnetic papers. Measuring the magnetic properties with vibrating sample magnetometer (VSM) demonstrated the superparamagnetic behavior of fabricated papers. Magnetization at saturation (Ms) of the papers was increased by increase in loading degree.
