| Popis: | The structural, magnetic and electrophysical properties of composites based on nanosized magnetite chemically modified of copper iodide and polychlortrifluoroethylene have been studied at temperatures 298 – 450 K and CuI concentrations of from 0 to 0,58 volume. It has been found the optimal volume content of copper iodide ( 0,4) in the composites CuI/Fe3O4, when the interfacial interaction shows most intensively and maximum values electrical parameters take place. The value of the coercive force of nanocomposites CuI/Fe3O4 increases with increasing content copper iodide. It was shown that polymer composites containing CuI/Fe3O4, have higher values of real and imaginary components of complex permittivity and conductivity compared with a system that contains only copper iodide. Keywords: magnetite, copper iodide, nanocomposites, specific magnetization, interfacial interaction. |
