感温磁性流体マイクロカプセルの合成と流れ場可視化

抄録

In this study, a new magnetic material is made by microencapsulating the Temperature-sensitive magnetic fluid. Microcapsules are made by dissolving the organic solvent, polymer, Temperature-sensitive magnetic fluid, dropping it into pure water and stirring with a homomixer. The prepared microcapsules are observed with SEM. Fluorescence observation of particles and visualization of flow field are performed by mixing fluorescent dye in microcapsules. As the results it was confirmed that microcapsules form clusters by supplying a magnetic field. A self-made magnetic capsule containing a fluorescent paint could be visualized in a flow field with a magnetic field supplied.

It was shown that PIV measurement is possible by adjusting the particle density.
