Study the Effects of SiO2 Nanoparticle on the Hydrophobic Properties of PVDF Composit Membrane

By using SiO2 nanoparticles and polyvinylidene fluoride (PVDF), membranes with high hydrophobicity viaphase separation technique produced. The effect of nanoparticle concentration on the morphology and hydrophobicitymembranes have been studied. The morphologies and hydrophobicities of PVDF microporous membranes wereinvestigated by Scanning Electron Microscopy (SEM) and Contact Angle (CA) measurement. The maximum watercontact angle of 1320was observed.
