Amorphous Magnetic Films for Yocto Energy Shielding (AMFYES)

The rapid advancement of modern electronics, wireless communications, and quantum technologies has intensified the issue of electromagnetic interference (EMI). This interference can disrupt signal integrity, diminish device reliability, and pose risks to critical systems. Traditional EMI shielding materials, such as metallic coatings, tend to be inflexible, bulky, and primarily reflective, making them unsuitable for flexible, wearable, and compact devices. To overcome this limitation, there is a need for lightweight, flexible, and absorption- dominant materials that can effectively suppress EMI. The synthesis of molybdenum disulfide (MoS2) will be conducted using a hydrothermal process at the materials level. Machine learning models will be employed to predict the compositions of magnetic glasses. These magnetic glasses will be designed to enhance magnetic permeability and tailor magnetic losses, thereby facilitating absorption-dominant shielding. The MoS2 and magnetic glasses will be evenly dispersed within a polyvinylidene fluoride (PVDF) polymer matrix to create flexible composite films through a screen printing method. This project aims to develop an absorption-dominant flexible EMI shielding material by integrating magnetic glass (MG), two-dimensional molybdenum disulfide (MoS2), and PVDF polymer into a composite film. The composite film will interact with electromagnetic waves, and its EMI shielding parameters will be studied and simulated using CST Studio Suite software before being practically optimized.
