Abstract in another language

Short electrospun fibers were obtained by using UV cutting method. Either polymers with double bonds with a photocross-linker (CL) and photoinitiator (PI) or known photochemistry of coumarin (2 + 2 cycloaddition reaction) without the addition of CL and PI is utilized for making short electrospun fibers. The electrospun fibers were irradiated by UV light in the presence of a mask with a defined width of slits. The uncovered parts of fibers were cross-linked and therefore became insoluble. The non-cross-linked parts were removed by immersion of the fibers into an appropriate solvent. The length of obtained short fibers can be controlled by changing the width of the slits of the employed mask.
