Improvement of electrospun polymer fiber meshes pore size by femtosecond laser irradiation

▶ Micropores can be formed in polymeric fiber meshes by laser irradiation. ▶ Pore size can be controlled by controlling laser parameters. ▶ Chemistry of the fibers is kept after femtosecond irradiation. ▶ Integrity of the laser irradiated fibers is kept (no sealed pores).
