(a) A representative SEM image (2000 × magnification) of a cross-section of a strip created using 0.8 mL/h core flow rate; (b) Box-and-whisker plots representing pore size (d_n) of five fiber strips. Median values, interquartile ranges (i.q.r.) and 1.5 times the i.q.r (excluding outliers ° and extreme values *) are denoted by horizontal bars, boxes and whiskers respectively. The variations in pore sizes were small but significant (Kruskal–Wallis, p < 0.01); (c) Plot of porosity for each of five strips.
