| Sumario: | A high-performance electromagnetic interference (EMI) shielding material, based on mulberry paper and fabricated using a screen-printing technique, has been developed to achieve excellent shielding effectiveness. The study systematically investigates the EMI shielding ability of a material by varying the concentration of MoS2/Co0.9Ni0.1Fe2O3 nanoparticles in a PVDF polymer matrix. Three different concentrations, namely 10 wt%, 20 wt%, and 30 wt%, are used. The CST simulation tool is used to forecast the electromagnetic compatibility and mode of electromagnetic wave propagation. Experimentally, the shielding effect of the screen-printed film with 30 wt% of MoS2/Co0.9Ni0.1Fe2O3 in PVDF revealed over 74.2 dB, which is the highest value of shielding efficiency in the X-band when compared to other fabricated films with 10 and 20 wt% of MoS2/Co0.9Ni0.1Fe2O3. Moreover, a durability test is conducted to check the dependence of the shielding efficiency of PMC films on mechanical bending for 10 000 cycles. This report presents electromagnetic interference shielding materials by screen printing a PVDF/MoS2/Co0.9Ni0.1Fe2O3 composite on mulberry paper with a high shielding effect. A remarkable degree of concordance exists between the simulation and experimental measurements. In addition, the produced flexible composite film successfully showed good impedance matching and higher attenuation constants of 103.11 and 123.64 for 30 wt% films, respectively. |
