Abstract: The present disclosure relates to polymer composites that include a thermoplastic polymer, network structure and a soft, ferromagnetic particulate material. The polymer composites may be used, for example, as magnetic flux field directional materials. The present invention also relates to methods of making the polymer composites, e.g. polymer composite sheets, of the present disclosure. In one embodiment, the present disclosure provides a polymer composite including a thermoplastic polymer, network structure; and a soft, ferromagnetic particulate material distributed within the thermoplastic polymer, network structure. The weight fraction of soft, ferromagnetic particulate material may be between 0.80 and 0.98, based on the total weight of the polymer composite and/or the thermoplastic polymer may have a number average molecular weight between 5×104 g/mol to 5×107 g/mol.
