چکیده مقاله
Membrane technology has gradually become a popular separation technology over the past
few decades. There are many significant advantages to use membranes for industrial processes.
MWCNT possible locations for small molecules are absorbed. Since the transmission properties of
CNTs is always the key issue is to improve the properties of polymeric membranes to separate the
CNTs are able to transfer the molecules studied. MWCNT/PVDF membranes were fabricated
using solution casting method. The synthesized membranes were structurally characterized using
Fourier transform infrared spectroscopy, scanning electron microscope and thickness of
membrane. The membrane performance was tested by vacuum membrane distillation setup. SEM
images showed appropriate distribution of multi wall carbon nanotubes within polyvinylidene
fluoride matrix. FTIR analysis showed a physically linking between the nanoparticles and the
polymeric matrix of the membrane. Thickness of membranes wasabout 40,50 µm. The MD
performance of neat PVDF and MWCNT/PVDF flat sheet membranes with the approximate
contact area of 32 cm
2
was examined in a vacuum membrane distillation setup. The pure water
flux for PVDF/MWCNT and neat PVDF membranes was 8.44 ,11.25(kg/m
2
h), Respectively. Pure
water flux test showed that increasing the nanoparticle, pore wetting is reduced. so, the
hydrophobicity is increased.
