X-ray, mechanical, thermal, rheology and optical data of melt-spun PCL filaments

WAXD and SAXS patterns of poly(ɛ-caprolactone) (PCL) monofilaments were recorded on a Bruker Nanostar U diffractometer (Bruker AXS, Karlsruhe, Germany) with a Cu-Kα radiation λ = 1.5419 Å and a VÅNTEC-2000 MikroGap area detector. Mechanical properties were measured with the tensile testing machine Statimat ME+ (Textechno, Germany). Thermal properties were characterized using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Rheological properties of the PCL polymer were characterized with the Rheometer Physica MCR 301 (Anton Paar), using a plate-plate geometry. The surface topography of fibers was analyzed using the scanning electron microscope (SEM) FE-SEM S-4800 (Hitachi High-Technologies Europe, Krefeld, Germany) with an acceleration voltage of 5.0 kV.
