Fig. 3: Effect of preparation conditions of (NixCoy)MnO/CNT on microwave absorption performance.
a Violin plots of the real (\(\varepsilon {\prime}\), red) and imaginary (\(\varepsilon {\prime} {\prime}\), blue) parts of the complex permittivity as a function of the NCM811/PE/PET mass ratio (left) and heating temperature (right). The central line indicates the mean value, and the inner lines represent the first and third quartiles (25th and 75th percentiles). Squares connected by dashed lines show the average values. Data were obtained from n = 3 independent measurements. Complex permittivity; EMWA performance of (Ni8Co1)MnO/CNT, (Ni8Co1)MnO/CNT-800, and, (Ni6Co2) MnO/CNT-800, (b–d), 2D RL values, e–g, impedance matching for |Z-1|, (h), attenuation constant, (i), polarization loss \({\varepsilon }_{p}^{{\prime} {\prime} }\) and conduction loss \({\varepsilon }_{c}^{{\prime} {\prime} }\) and (j), corresponding \({\varepsilon }_{p}^{{\prime} {\prime} }/{\varepsilon }_{c}^{{\prime} {\prime} }\).
