Abstract
The influence of mid-IR (1.94 μm) laser radiation on the morphology of polylactide and polycaprolactone nonwoven materials obtained by electrospinning has been revealed. It has been shown that laser irradiation makes it possible to achieve local structuring of the nonwovens at the micrometer level, in particular, to fuse individual fibers, straighten them between fusion points, and prepare monolithic films from the materials or, conversely, create breaks in them. The influence of laser irradiation parameters (power, laser spot speed, scan line density) and additional wetting of the samples on the structure of the nonwovens has been determined.
