“…Usually, the membranes employed in water filtering are polymeric, because of their lower cost and ease of processability; however, they do not present a high thermal and mechanical resistance, therefore reducing its lifetime. In order to increase the membrane life cycle, fillers are added such that they produce composite membranes with a higher performance and improved intrinsic features [5][6][7][8].…”

Polysulfone/ Recam® composite membranes were prepared via the wet-phase inversion method. The interactions between polysulfone and additive were revealed by Fourier-transformed infrared spectroscopy and atomic force microscopy. Material properties, such as thermal and mechanical ones, were also analyzed. The increase of rugosity by augmenting the Recam® content was depicted by AFM images. Infrared spectroscopy provided very useful information about the interactions between polymer chains and additive. Thermal stability and mechanical resistance showed dependence on the additive content, which were higher for higher contents.
