Abstract
The invention belongs to the technical field of wireless charging material preparation, and particularly relates to a nanocrystalline flexible sheet and a preparation method and application thereof. The nanocrystalline flexible sheet comprises the following components: Fe, Cu, Si, B, Nb, Mo and C, and further comprises rare earth metal, and the rare earth metal is at least one of Y, Dy, Gd, Tb, Ho, Er and Tm. When the nanocrystalline flexible sheet is used in the field of wireless charging, the power and efficiency of wireless charging can be improved, and the nanocrystalline flexible sheet has the advantage of being small in size and is beneficial for electronic equipment to develop towards the direction of higher frequency, higher efficiency and miniaturization; and meanwhile, the nanocrystalline flexible sheet has the condition of replacing ferrite to serve as a wireless charging material under the high-frequency working condition, and has the advantages of being high in magnetic conductivity, saturation flux density, magnetic conductivity and charging efficiency, low in temperature rise, small in size and the like at the same time.
