Crystallinity of Electrospun and Centrifugal Spun Polycaprolactone Fibers: A Comparative Study

Table 1

Overview of data obtained from DSC curves analysis for all tested fibrous and nonfibrous materials: (°C) melting temperature; (%) degree of crystallinity calculated from the 1st heating, cooling, and 2nd heating and width at half height (°C). Data represent average value and 95% confidence interval. The gray-tinged cells symbolize materials produced from raw PCL of molecular weight = 80,000 g/mol.
