During last few decades, membrane technology has emerged as an efficient technique over conventional methods due to its high removal capacity, ease in operation and cost effectiveness for wastewater treatment and production of clean water. Membrane based separations are commonly based on polymeric membranes because of their higher flexibility, easily pore forming mechanism, low cost and smaller space for installation as compared to inorganic membranes. Commonly employed membrane fabrication phase inversion method has been shortly reviewed in this article. Major limitation of membrane based separations is fouling and polymeric membranes being hydrophobic in nature are more prone to fouling. Fouling is a deposition of various colloidal particles, macromolecules (polysaccharides, proteins), salts etc. on membrane surface and within pores thus impedes membrane performance, reduces flux and results in high cost. Modification of polymeric membranes due to its tailoring ability with nanomaterials such as metal based and carbon based results in polymeric nano-composite membranes with high antifouling characteristics. Nanomaterials impart high selectivity, permeability, hydrophilicity, thermal stability, mechanical strength, and antibacterial properties to polymeric membranes via blending, coating etc. modification methods. Characterization techniques has also discussed in later section for studying morphological properties and performance of polymer nano-composite membranes. Graphical Abstract

“…8 Among these polymers, with excellent chemical, physical, and mechanical properties and outstanding thermal stability, PVDF has been widely used to produce microporous membranes for VMD processes. [21][22][23][24][25][26][27][28] For the fabrication of PVDF membranes, there are several different methods, such as the non-solvent-induced phase separation (NIPS) process, [29][30][31] thermally induced phase separation process, 32,33 and vapor-induced phase separation process. 24 Among these processes, NIPS is the mostly used for its flexibility in the selection of solvent and nonsolvent.…”

“…During the precipitation, the polymer demixing rate and phase-separation patterns (liquid-liquid and liquid-solid) can affect the structure and properties of the microporous membranes. 21,[25][26][27][28] The factors that may influence precipitation rate include the choice of polymer, 23 For the preparation of PVDF microporous membranes used for MD processes, the usual solvents used to dissolve PVDF include N,N-dimethylformamide, 2 N,N-dimethylacetamide (DMAc), 9,16,22,23 and N-methylpyrrolydone; 27 and the usual coagulation baths include water, ethanol, and their mixtures. 8,23 The rapid precipitation rate of casing solution creates a fingerlike macrovoid structure, whereas the low precipitation rate creates a spongelike structure or spherulite formation.…”

“…The spongelike structure is more favorable than the fingerlike structure for improvements in the membrane porosity and mechanical properties, which are important factors related to the MD performances. [21][22][23][24][25][26][27][28] In recent years, an increasing number of researchers have investigated ways to improve the VMD performance of a PVDF microporous membrane fabricated via NIPS processes. Simone et al 8 found that the properties of microporous hydrophobic hollow fibers were strongly influenced by the composition and flow rate of bore fluid.…”

The objective of this study was to investigate the effects of the exposure time on the properties and permeability of polydimethylsiloxane (PDMS)-poly(vinylidene fluoride) (PVDF) blend hydrophobic microporous membranes, which were fabricated via a non-solvent-induced phase separation process at 25 8C and 60% relative humidity in a clean-room circumstance. For the prepared PDMS-PVDF membranes, the membrane morphologies were observed by scanning electron microscopy. Crystalline structures were observed by X-ray diffraction. Pore structures were analyzed by membrane porosity and mean pore size. Hydrophobicity was measured by contact angle measurement, and the mechanical properties were characterized by tensile strength testing. Our study results show that with increasing exposure time from 10 to 110 s, all of the membranes showed a similar pore structure: a spongelike substrate layer with a thin realm of fingerlike structures under the top surface. Phase separation between PDMS and PVDF occurred. The membrane porosity and mean pore radius decreased, and the membrane thickness increased. The membrane hydrophobicity decreased, and the mechanical properties first increased and then decreased. In addition, vacuum membrane distillation experiments were conducted. With the increase in the exposure time from 10 to 110 s, the membrane permeate flux decreased from 16.54 to 6.65 kg m 22 Áh 21, and the salt rejection was higher than 99.9%.

“…Lewandowska 13 estudou a produção de blendas envolvendo a PVP e o acetato de quitosana, verificando que a miscibilidade é dependente da massa molar da PVP e do teor de umidade. Simone e colaboradores 14 produziram blendas de PVP e poli(fluoreto de vinilideno) (PVDF) para aplicação em membranas para destilação a vácuo e verificaram que a concentração de PVP é decisiva nas características físicas finais do material, podendo variar desde membranas altamente porosas com grandes cavidades até estruturas esponjosas de baixa porosidade. Saljoughi e Mohammadi 15 estudaram a aplicação de blendas de PVP e acetato de celulose em sistemas de osmose reversa e ultrafiltração e também verificaram a influência da concentração de PVP na formação de estruturas porosas.…”
