SEM (Tescan Vega (LMU)) was used to look at the cross-sectional and area morphology of the membranes of various NP loadings (Determine 1 and Figure S1). Membranes ended up broken in liquid nitrogen to fix the cross-sectional finishes in the membranes and also a voltage of 15–20 Kv at different magnifications was used with gold coating with the sa
