| 1. A method for making a nanomaterial, comprising:
dissolving and/or suspending a combination of (a) one or more resin substrate materials and (b) one or more magnetic nanoparticulate
substances, in a medium comprising one or more ionic liquids, to provide a mixture; and
recovering a solid nanomaterial comprising the one or more resin substrate materials having the one or more magnetic nanoparticulate
substances distributed therein, by combining the mixture with a non-solvent;
wherein during the recovery step, an electromagnetic field is applied to the mixture to align the one or more nanoparticulate
substances within the one or more resin substrate materials.
