Abstract
The continuous development of hybrid and composite materials opens new avenues for precisely tuning and adjusting the transport properties of functional polymers. This study presents novel composite membranes, incorporating different types of magnetic fillers with distinct magnetic properties into a polymer matrix, prepared both with and without the application of an external magnetic field.
The hybrid strategy leverages the magnetic heterogeneity to modulate key physicochemical properties of the membrane, such as molecular diffusion, sorption dynamics and selective permeability - all of which govern the overall separation performance. These effects are closely linked to the type, size, distribution, and magnetic character of the fillers, as well as the local magnetic fields they generate. Such magnetically responsive behaviour is particularly advantageous in processes requiring fine control over the transport of polar molecules - for instance, in the dehydration of bio-alcohols for biofuel applications. The combination of fillers with diverse magnetic properties, along with membrane prepared in an external magnetic fields results in structurally dynamic membrane domains that interact actively with permeating molecules. This responsiveness aligns with the concept of ‘smart materials’, where the filler network contributes functionally, beyond merely reinforcing the structure.
Our findings highlight that the magnetic infuence in membranes plays a key role in shaping the internal membrane environment, enabling the formation of directed transport channels and offering tunable selectivity.
