NOVELTY - Preparation of iron oxide-graphene oxide-aqueous polyurethane composite involves mixing graphene oxide suspension and iron oxide powder, ultrasonically processing, stirring for 1-2 hours, obtaining iron oxide-graphene oxide colloid, mixing resultant with 24-36 wt.% aqueous polyurethane emulsion, adding N,N-dimethyl-dicarboxamide, mixing at room temperature, ultrasonically dispersing for 0.9-1.3 hour, adding to polytetrafluoroethylene membrane, curing at room temperature and drying at 75-83 degrees C for 12-14 hours. USE - Preparation of iron oxide-graphene oxide-aqueous polyurethane composite (claimed). ADVANTAGE - The method enables preparation of iron oxide-graphene oxide-aqueous polyurethane composite having excellent dispersibility, electroconductivity, magnetic permeability and thermal conductivity, by simple and economical process.
