Abstract: A method of obtaining free graphene films using intercalation and subsequent thermal expansion of crystalline graphite is suggested. Thermally expanded graphite prepared by microwave irradiation is examined under a scanning electron microscope. It is found that it contains fragments of free graphene films. The conclusion is drawn that this method is promising for obtaining graphene suitable for experimental research.
