제목 The dispersion of the magnetite depending on the pH in the hydrogel
초록 Recently, much attention has been focused upon sensors and actuator in polymer gels. Electromagnetic active hydrogel can be considered as one of the intelligent materials. We have studied the kinetics of the movement of electromagnetic gel. The actuation mechanism is based on magnetite diffusion. We used the buffer solution to improve the dispersion of the magnetite in the poly(acrylic acid) hydrogel.
The magnetite nanoparticles was prepared from FeCl2 and FeCl3 in distilled water. Particle size of magnetite nanoparticles was measured by Atomic Force Microscope(AFM). We used the standard buffer solution and observe the dispersion of the magnetite. The result was that magnetite very well disperse in acidity buffer solution. The magnetite was aggregated in alkalinity buffer solution.
