The observed X-ray reflections appear to correspond to the (0 2 0), (1 1 0) and (0 2 1) reflections of PVDF [17] but the relative intensities do not indicate the possibility of a different crystal structure. The proposed solution for this issue was to fabricate membranes with hydrophobic properties.
