چکیده انگلیسی
A novel approach, continuous needleless electrospinning from the tips of magnetization-induced self-assembling PVA/ferrofluid cone array, was proposed to prepare magnetic nanofibers. A PVA/ferrofluid was synthesized, the needleless electrospinning process was observed, and the morphology and magnetic properties of magnetic nanofibers were investigated. The results showed that the PVA/ferrofluid could remain stable and homogeneous for 21â¯days under the magnetic field gradient (2.2â¯mT/mm). “Taylor cone” array of PVA/ferrofluid was self-assembled under both the magnetic and electric fields. As the electric voltage reached 25â¯kV, the jets were emitted from the “Taylor cone” array, resulting in needleless electrospinning of magnetic nanofibers. Magnetic nanofibers were homogeneous and continuous with an average diameter of 73.6â¯nm. Magnetic nanofibers showed a good magnetic response property and relatively high saturated magnetization (1.71â¯emu/g), which is expected to be applied in the biomedical field.
