The goal of this work is to fabricate a new composite based on polyurethane (PU). grapefruit (GP) oil. and cobalt nitrate [Co(NO3)2] using an electrospinning technique. Morphology results revealed the reduction in the fiber diameter of the composites compared to pristine PU control. https://www.bekindtopets.com/mega-pick-Silbrade-Braid-Reinforced-Silicone-Tubing-1-4-ID-x-520-OD-x-1-hot-grab/
