Magnetic-field-induced synthesis of magnetic wire-like micro- and nanostructures


A lot of physical and chemical preparation methods of one-dimensional (1D) structures are known today. Most of them use the highly-advanced technology or the quite complex chemical reagents. This results in their high costs and difficulties with their implementation to a large industrial scale. Hence, the new, facile and inexpensive approaches are still sought. One alternative of wire-like structures production is based on the chemical reduction reactions combined with an external magnetic field which acts as an independent synthesis parameter. This approach is commonly called as magnetic-field-assisted (MFA) synthesis or magnetic-field-induced (MFI) synthesis. As usual, this manufacturing strategy comprises both drawbacks and advantages which are introduced in this review. Moreover, this work shows that the MFI synthesis depends on several synthesis parameters including strength of applied magnetic field, reaction temperature, pH value of reaction environment, chemical composition of precursor solution, reaction time, and also presence of surfactants, complexing agents, nucleating agents, initiators as well as organic solvents. All of them have an impact on the morphology and dimensions of wire-like materials and their chemical, physical and mechanical properties. Finally, the opportunities and challenges associated with the magnetic-assisted fabrication of wire-like structures are widely discussed in this review.
