For the [10]CPP-PCL samples, this statistical difference is due to a bimodal distribution of fiber diameters (i.e., both smaller and large fiber diameters), while the average diameter was similar to [8]CPP-PCL and [9]CPP-PCL solutions. This result could be attributed to either the [10]CPP within the material or, potentially, to the inherent variability that can occur for the SES process .
