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.roneverhart.com/Terry-s-Milk-Orange-Chocolate-with-Popping-Candy-12-Piece-Case/
