“…The mechanical properties of the membranes were measured by means of a DMA 8000 (Perkin Elmer Waltham, MA, USA) in the so-called “tension configuration”, on small membrane pieces that were 4–6 mm wide, 10–12mm long, and 0.10–0.15mm thick [18,19,20,21]. The samples were cut from the various membranes dried in an oven, at 80 °C (dry samples), or immersed in bi-distilled water, at room temperature (wet samples).…”
