Tierno, P. et al.

Using paramagnetic particles as repulsive templates for the preparation of membranes of controlled porosity.

Using mixtures of repulsive superparamagnetic polystyrene particles and a photopolymerizable organic liquid (trimethylolpropane trimethacrylate) that are applied to a water surface, it is possible to prepare porous membranes with controlled porosity. The particles were polarized by applying a magnetic field H perpendicular to the interface and spread out over the interface making use of the induced repulsive magnetic dipole interactions. As a consequence, the organic liquid in which the particles were embedded covered the water surface uniformly. Subsequent photo cross linking of the organic liquid and dissolution of the embedded particles gave rise to membranes whose porosities were controlled mainly by the chosen areas per particle. The spatial distribution of the pores and the deviation from a crystalline arrangement were characterized in terms of the 2D pair-correlation function and the mean nearest-neighbor interpore distance.[1]
