Dielectric behavior and magnetic properties of poly(styrene-co-acrylic acid)metal microspheres

Poly(styrene-co-acrylic acid)metal (P(St-co-AA)metal) particles were prepared by chemical metal deposition. Characterization was carried out by transmission electron microscopy and X-ray diffraction. Dielectric behavior and determination of magnetic properties of P(St-co-AA)metal microspheres were investigated. Thermogravimetric analysis showed that the Curie temperature (TC) of P(St-co-AA)metal was lower than the TC of the corresponding block metal and fine metal particles. The susceptibility and hysteresis loop of P(St-co-AA)metal were studied. The results showed that the composite particles are soft magnetic materials.
