In summary, increasing fiber and binder concentration generally reduces porosity while increasing tortuosity. Electrical and thermal conductivities (IP and TP) tend to rise with increasing fiber diameter due to its conductive nature. Resistivity and diffusivity decrease with these changes. The complete correlation (Figure ) and partial correlation (Figure ) matrices are provided in the supplementary information for further reference. Similar trends are also observed on the correlation (Figures S5) and partial correlation (Figures S6) matrices of the domain size 2000 µm × 200 µm dataset. Therefore, in general, the correlation analysis is independent of the domain size dataset.
