Abstract
Electromagnetic shielding materials are those that can mitigate electromagnetic interference (EMI) by absorbing, reflecting, or scattering electromagnetic waves. With the advancement of research, electromagnetic shielding materials are not only expected to have high EMI shielding effectiveness but also to integrate other functional properties. In this study, a flexible self-adhesive electromagnetic shielding film with high shielding effectiveness (SET), named rGO@DTPP, has been developed. Leveraging multiple loss mechanisms, the SET of rGO@DTPP can peak at up to 55 dB. Additionally, it possesses excellent self-adhesive properties, enabling it to adhere to a variety of material surfaces. Notably, it exhibits a high adhesive strength of 0.21 N/cm on the skin surface. The composite film also has breaking elongation of up to 40 %, and it features a highly conductive thin film when in contact with the skin, thus adhering well to the skin's surface. This makes it an outstanding material for flexible, wearable applications.
