Abstract
The superparamagnetic nanoparticles were prepared by coprecipitation of $FeCl_3$ and $Na_2SO_3$ with $NH_4OH$ and the surface charge on hydroxyl group by chemisorption was changed depending on pH. We studied correlation between surface charge of magnetite and pH. Using this correlation the properties of poly (acrylic acid) (PAAc) hydrogel embedded with magnetite was studied. The magnetite was characterized by XRD, AFM. and FTIR. The zeta-potential of magnetite was influenced by pH: great positive charge was shown high under the pH 4 and isoelectric point was found at pH 7. The hydrogen bond formed by combining oi PAAc hydrogel and magnetic colloid under pH 4 caused tensile strength to increase, while swelling and elongation at break to decrease. The result confirmed that the magnetic moment was increased proportionally to the content of magnetite.
