Fabrication and Simulation of Flexible Screen‐Printed Mulberry Paper‐Based Multiferroic Composites as Microwave Absorption Shields

Abstract

Flexible paper‐based electronics are trending currently for its biodegradability, light weight, and compactness. A flexible film with 10, 20, 30 wt% of BCST‐CNF multiferroic filler is systematically investigated by initially simulating electromagnetic interference (EMI) shielding parameters using CST Studio Suite Software. Nicolson–Ross wire algorithm is used to estimate the EM parameters of PVDF/(Ba0.945Ca0.055Sn0.07Ti0.93)O3–Co0.9Ni0.1Fe2O4)(BCST‐CNF) (PBC) films. By adaption of PBC on mulberry paper, the shielding effect of the screen‐printed EMI shielding material with 30 wt% of multiferroic filler reveals over 65.24 dB, which is the highest value of shielding effect for X‐band compared to other tested films. Moreover, it shows enhanced microwave absorption of 63.48 dB. This study opens up an effective avenue for designing strong microwave absorption materials to satisfy the increasingly demanding requirements of advanced and integrated electronics.
