17In this study we present the use of co-axial electrospinning to produce core-shell composite micro- 18/nano-fibers of Polyurethane (PU) and Cellulose acetate phthalate (CAP). The designed fibers possess 19 enhanced mechanical properties with a tensile strength of 13.27±2.32 MPa, which is a clear 20 improvement over the existing CAP fibers that suffer from a poor mechanical strength (0.2±0.03 MPa). 21The CAP imparts pH responsiveness to the core-shell structure giving the fibers potential for "semen 22 sensitive" (intravaginal) drug delivery.

In recent years, both the increasing frequency of oil spill accidents and the urgency to deal seriously with industrial oil-polluted water, encouraged material scientists to design highly efficient, cost effective oil–water separation technologies.
