In this study, the effects of hot airflow on macromolecular orientation
and crystallinity of melt electrospun PLLA fibers were
explored. In specific, five types of PLLA fibers (with diameters in
microns) were prepared via melt electrospinning at 200 °C with or
without hot airflow; and the hot airflow was set at two (i.e., slow
and fast) speeds and two temperatures (i.e., 80 and 120 °C)
