Abstract

This work describes the synthesis of polysaccharide-based magnetic hydrogels with the introduction of magnetite nanoparticles in the polymer network. The magnetic hydrogels were characterized by Fourier-transform infrared spectroscopy (FTIR) and magnetization curves. FTIR analysis confirmed the efficiency of the polysaccharide-modifying process. The amounts of diffused water into or out-of a hydrogel network were measured. The degree of swelling of the polysaccharide-based magnetic hydrogels was less than that found for the regular polysaccharide-based hydrogels and there was no variation in the water diffusion mechanism. The absence of hysteresis loops and coercivity observed through magnetization curves indicated that magnetic hydrogels can be applied in external-controlled solute release.
