Figure 5. Electromagnetic shielding performance of the hydrogels. (A-C) Clearly illustrate the influence of frequency on the SET, SER, and SEA of the hydrogels; (D) Average SET, SER, and SEA values of hydrogels; (E) Electrical conductivity of the hydrogels; (F) T-R-A coefficients of the hydrogels; (G) Electromagnetic shielding mechanism of the hydrogels. Data are presented as mean ± SD (n = 3); error bars represent standard deviation. PG: Polyacrylamide/glycerol; SET: total shielding effectiveness; SER: reflection shielding effectiveness; SEA: absorption shielding effectiveness; SD: standard deviation.
