Preparation and characterization of polyamide thin-film composite (TFC) membranes on plasma-modified polyvinylidene fluoride (PVDF)

A recent progress in thin film composite membrane: A review

“…The promising results can be explained by the fact that the high mechanical strength of substrate produced, which resists pore expansion as temperature increases. Kim et al [56] on the other hand proposed to use superior modified polyvinylidene fluoride (PVDF) as replacement for support layer because fluorinated polymers demonstrated relatively high mechanical strength and good resistance to chemical compared to PSF-based support substrate. Prior to IP process, plasma treatment on the PVDF membrane surface was conducted to improve its hydrophilicity so as it was suitable for fabrication of a PA-PVDF TFC membrane.…”

Hydrophilicity, morphology and excellent adsorption ability of poly(vinylidene fluoride) membranes induced by graphene oxide and polyvinylpyrrolidone

“…For example, Kim et al [17] used a low temperature plasma-treatment technology using oxygen as the reactive monomer to modify a commercial PVDF membrane and they found that plasma treatment of PVDF membrane produced a hydrophilic surface and then significantly reduced its water contact angle. Wang et al [18] first prepared the hydrophilic PVDF material through ozone-induced grafting polymerization of acrylic acid on PVDF chains, and then they used the material to prepare PVDF membrane through the non-solvent induced phase separation method.…”

“…Moreover, PS is relatively hydrophilic, and especially suitable for the interfacial polymerization of PA in aqueous solution [88]. Studies revealed that further improvement of PA substrate, such as via plasma treatment, assisted in the preparation of high-performance PA membranes [88][89][90].…”

“…The use of inorganic nanoparticles in PS led to the formation of nanocomposite substrate materials with enhanced mechanical stability, which resisted physical compaction of its supported PA membranes [91]. To develop TFC membranes with high operating temperature and chemical stability, considerable efforts have been made to explore other polymers as the support layers, including poly (pathalazinone ether sulfone ketone) (PPESK) [92,93], poly (phthalazinone ether amide) (PPEA) [94], polyvinylidene fluoride (PVDF) [88], and polypropylene (PP) [89].…”
