There are influence of  Fe/C as polymer composition component studied, for use as PCM of special purposes, on structure, mechanical, and electrophysical properties, when regarding to goal for usage possibilty establishing  for carbon and iron-containing material of Fe/C, and last was synthesized with CVD technique on iron-containing catalyst. There were PEHD- and nano-disperse addition of Fe/C - based composite films prepared, with hot pressing method, of mass equation in 42/58 for Fe/C, and  addition content in PCM of   1 – 15 % mass.  Then, there were films oriented with thermogradient hot stretching.. It is established, that Fe/C presence is decreasing for maximal stretching value λmax, for pure HDPE, to 5 for highly-loaded compositions. There are addition’s influence on PE phase transitions  in composite films: when at low addition’s contents, then, there are forming more perfect crystallic structure of more larger and uniform crystallites by dimensions, but, at those higher - less uniform one. It is established, that specific saturation magntetization values (σs ), for composite and non-oriented films, are increasing, from 1.1 Gs∙cm3/g for film of 5 %mass. of Fe/C,  to 5.6 Gs∙cm3/g (film of  15 % mass. Fe/C). There are cohertzitive power values, changing dependently from Fe/C comtent, from 97 to 99 E. It is founded, that electrical conductivity values (s), at  frequency of 1 kHz , is absent, for non-oriented film of 1 %mass. Fe/C (σ=9,4∙10-11 Om-1cm-1), but, for those non-oriented ones of  5- 15 %mass. are 2,4∙10-5 ‒ 1∙10  Om-1cm-1. Where are orientational stretching actions, there are decreasing in electrical conductivity values - σ=1,4∙10-12‒2,7∙10‑1 Om-1cm-1 for films of   λ=5‒6. Those films, when at own intrinsic structure-mechanical, electrical and magnetic properties, depending of Fe/C content,  are perspective ones as magnetic, anti-static and electrical conductive materials.
