Magnetic membranes are membranes that show a measurable, nonzero, magnetic induction. Since we consider the membranes for separation, they belong only to two classes, i.e., polymeric (organic) and inorganic (ceramic) (Baker 2004; Li 2007). In both types of matrixes the magnetic powder can be dispersed, and after the membrane is formed, it is exposed to a strong magnetic field for final magnetization. Depending upon the size of the magnetic powders used as fillers, we can have: milli-, micro-, and finally nanomagnetic membranes. The process of formation is crucial in case of magnetic membranes. So far the classical casting methods have been used (Rybak et al. 2009; Dudek et al. 2012) by which the polymer solution with a magnetic powder in it is kept under the weak magnetic field to prevent the powder from sedimentation and to stimulate the formation of pores. The final structure of pores is crucial for transport properties of magnetic membranes. There are quite a few options here....
