Influence of Sodium Maghnite Nanoclay on the Polyvinylidene Fluoride Crystal Transition in Composite Membranes and Its Effect on Bovine Serum Albumin Protein Extraction

Abstract

The crystal structure of poly (vinylidene fluoride) (PVDF) and morphology of composite membranes prepared from mixture of PVDF, Polyvinylpyrrolidone (PVP) and Sodium Maghnite nanoclay has been investigated in this research work. Several analytical methods were used for the characterisation of synthesised membrane samples such as FTIR spectroscopy, X-ray diffraction (XRD), porosity and contact angle It was found the effect of adding of increasing amounts of Maghnite can improve the piezoelectric phase of PVDF. These is confirmed by the increase of the Beta crystal phase ratio. It was proved also that the synthetised membranes occurs different interaction with Serum Albovine protein by the increase of the fouling index fluxes for the membrane with reach content of Maghnite. Which confirm that the deposition effect of BSA in the membrane surface with high amounts of beta crystal structures.
