Fig. 4. (a) The effect of silver nitrate solution addition on EMI SE of different MCS composite membranes with different thickness in the X-band region; (b) comparison of total EMI shielding effectiveness (SETotal), microwave absorption (SEA), and microwave reflection (SER) at a frequency of 12.4 GHz of the MCS composite membranes with different silver nitrate solution; (c) comparison of the specific EMI shielding effectiveness of different materials (i.e. carbon-based, MXene-based, CNT-based, and MCS composite membranes); (d) effect of silver nitrate content on the SSE/t of the MCS composite membranes with different silver nitrate contents in the X-band region; (e) proposed EMI shielding mechanism of the MCS composite membranes.
