Abstract
Nonwoven materials with an average fiber diameter of 4.7 μm and 3.9 μm were prepared by electrospinning of a heated solution and melt of the thermoplastic polyolefin elastomer – ethylene-octene copolymer. The materials prepared from the melt have fibers with a smooth surface, while materials produced from a heated solution have “shish-kebab” morphology with highly extended surface. X-ray diffraction analysis data demonstrates increasing of the mesophase content in the fibers prepared from the melt and the orthorhombic crystalline phase – for a heated solution. The produced nonwovens show superhydrophobic and oleophilic properties, high sorption capacity (up to 109 g/g for motor oil) and can be used for various applications, e.g. oil removal from water surface and matrices in tissue engineering.
