“…Hua et al utilized ZIF-90 NPs to fabricate NCMs with Matrimid ® polymer for IPA dehydration [ 148 ]. NCMs composed of phosphotungstic acid in SA for dehydration of alcohol by PV has been studied [ 160 ]. The incorporation of nanosized SA zeolite materials into the PVA matrix exhibited a fairly high water flux and reasonable SF for n-butanol-water system.…”

Pervaporation (PV) has been considered as one of the most active and promising areas in membrane technologies in separating close boiling or azeotropic liquid mixtures, heat sensitive biomaterials, water or organics from its mixtures that are indispensable constituents for various important chemical and bio-separations. In the PV process, the membrane plays the most pivotal role and is of paramount importance in governing the overall efficiency. This article evaluates and collaborates the current research towards the development of next generation nanomaterials (NMs) and embedded polymeric membranes with regard to its synthesis, fabrication and application strategies, challenges and future prospects.

“…Glutaraldehyde is most commonly employed as a cross-linker to form sodium alginate membranes [83][84]. These membranes cross-linked with glutaraldehyde were developed for use in organic dehydration by pervaporation [66,79,82]. A sodium alginate membrane cross-linked with phosphoric acid was prepared for pervaporative dehydration of ethanol aqueous solution [67].…”

Membranes prepared from oceanic biopolymers have a high potential in membrane separation processes and water purification. It is anticipated to result in more biocompatible and lower-cost materials compared with artificial polymers. This chapter describes the excellent performance of oceanic biopolymer membranes in separation engineering and the regulation factors controlling membrane properties. In particular, chitosan and alginate were picked up as intelligent membrane materials to provide the promised molecular size recognition and other membrane properties. Future prospective strategies for a simple methodology for preparing stable membranes from oceanic biopolymers and the development of selective separation processing were reviewed.

“…Permeation of diffusing molecules pass through the membrane becomes easier, therefore, the mass transport is faster and the total flux increases. What's more, as the temperature increased, the thermal mobility and the free volume of polymer were elevated, which led to the increase of the solubility of solution on the surface [29,30]. Meanwhile, the activation energy for permeation through the membrane can be described by Arrhenius relationship in Eq.…”
