Inherently Magnetic Hydrogel for Data Storage Based on Magneto-Optical Kerr Effect

Abstract

In this data explosion age, numerous data is generated every day. Such a fast data growth has aroused great interests in the field of data storage. Conventional data storage materials are mainly formulated by hard and brittle materials that they may be broken in the cases of mechanical operations, causing invocatable data loss. In this work, efforts are devoted to fabricating a flexible and stretchable double network hydrogel for data storage based on Magneto-Optical Kerr Effect. The hydrogel possesses the storage modulus over 104 Pa and remains unbroken under the strain of 3000%. The surface of the hydrogel is patterned with diamagnetic parts and paramagnetic parts alternately. Placed under magnetic field, the surface of the hydrogel reflects the incident laser and changes the polarization plane of the reflected light. The outstanding flexibility and inherent magnetic property of this hydrogel lays groundwork for the data storage and guarantees the data safety.
