Fig. 2: Electrical conductivity, microwave shielding, and mechanical properties of PP@AW hybrid membranes.

a Electrical conductivity of PP@AW hybrid membranes with different Ag/W ratios. b Microwave shielding effectiveness SET of PP@AW hybrid membranes with different Ag/W ratios. c SET of PP@AW24 hybrid membranes with different thicknesses. d Shielding performance of PP@AW24 hybrid membranes, the detailed contribution of SEA and SER to total SET and their dependence on frequency. e Mechanical flexibility and durability of hybrid membranes. The PP@AW24 membrane was flexible enough to retain its structural integrity even after 2000 bending cycles and there were negligible changes in its SET values as shown in f.
