| Summary: | <span>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 (</span><img src="http://www.pu.if.ua/inst/phys_che/start/pcss/vol18/images/anote1802_12_htm_eqn24329.gif" border="0" alt="" /><span> 0,4) in the composites CuI/Fe</span><sub>3</sub><span>O</span><sub>4</sub><span>, when the interfacial interaction shows most intensively and maximum values electrical parameters take place. The value of the coercive force of nanocomposites CuI/Fe</span><sub>3</sub><span>O</span><sub>4 </sub><span>increases with increasing content copper iodide. It was shown that polymer composites containing CuI/Fe</span><sub>3</sub><span>O</span><sub>4</sub><span>, have higher values of real and imaginary components of complex permittivity and conductivity compared with a system that contains only copper iodide. </span><br /><strong>Keywords:</strong><span> magnetite, copper iodide, nanocomposites, specific magnetization, interfacial interaction.</span> |
