“…glassy polymers with a high free volume content, such as PTMSP, PMP and PIM-1 [45][46][47][48][49][50][51][52], are the promising membrane materials for diverse applications. Due to the rigid nature of their macromolecular chains (T g >200 o C), the porous structure provided by the free volume elements with the dimensions of about 1 nm is formed upon casting from polymer solutions, and no subsequent treatment (e.g.…”

“…As a result, the intrinsic microporous structure of PTMSP is responsible for much higher ethanol permeability as compared with the permeability of rubbery polymers such as the cross-linked polydimethylsiloxane or polyurethane (see Fig. 5) [45,46,49]. Fair mechanical characteristics of PTMSP and PIM-1 allowed their application as thin film selective layers (with a thickness below 1 µm) in the preparation of the high-performance OSN membranes [47,50].…”

“…Among these developed materials, glassy polymers with a high free volume fraction have generated significant concern due to their intrinsic microporosity. [98][99][100][101][102][103] NF membranes based on these polymers are expected to have a high flux and result in a high rejection due to their higher diffusion. Volkov et al [98][99][100][101] fabricated SRNF membranes using a type of glassy polymer with a high free volume fraction (up to 25%), named poly(1-(trimethylsilyl)-1-propyne) (PTMSP).…”

“…They found that dense PTMSP membranes with a thickness of approximately 24-30 μm were much more permeable to ethanol than commercial silicone-based membranes. 98 Furthermore, PTMSP has also been used to fabricate thin selective layers on a porous PAN support. Optimized PTMSP/PAN composite membranes with a selective-layer thickness of approximately 1 μm showed an ethanol permeability of 3.8 kg m −2 h −1 bar −1 and a 90% rejection of Remazol Brilliant Blue R (MW 626.5) at 5 bar.…”

Recent Advances in Polymeric Solvent‐Resistant Nanofiltration Membranes

When considering energy consumption and environmental issues, solvent-resistant nanofiltration (SRNF) based on polymeric materials emerges as a process for substituting conventional separation processes of organic solutions, such as distillation, which consume high amounts of energy. Because SRNF does not involve phase transition, this process can potentially decrease the energy consumption and solvent waste and increase the yield of active components. Such improvements could significantly benefit a number of fields, such as pharmaceutical manufacturing and catalysis recovery, among others. Therefore, SRNF has gained a lot of attention since the recent introduction of solvent-stable polymeric materials in the manufacture of nanofiltration membranes. The membrane materials and the membrane structures depending on the fabrication methods determine the separation performance of polymeric SRNF membranes. Therefore, this article gives a comprehensive overview of the current state-of-art technologies of generating membrane materials and corresponding fabrication methods for SRNF membranes made from polymeric materials expected to provide the most benefit. The transport mechanisms and the corresponding models of SRNF membranes in organic media are also reviewed to better understand the mass transfer process. Various SRNF applications, such as in pharmaceutical and catalyst, among others, are also discussed. Finally, the difficulties and future research directions to overcome the challenges faced by SRNF processes are proposed. C

Solvent‐resistant nanofiltration (SRNF) is a separation technique that allows separations in organic solvents down to a molecular level. It is a growing technology that is environmentally friendly because of its energy‐ and waste‐efficiency. This article comprises a general introduction to SRNF, explaining its basic principles and considerations. Different methods to evaluate SRNF performance are discussed as well as limitations and challenges of the separation method. A more fundamental discussion of the possible transport mechanisms for different types of SRNF membranes is given. Currently used characterization methods, both novel and state of the art, are listed and discussed. An up‐to‐date overview of SRNF membranes types found in recent literature is given, with subdivisions made for each type of material. Their preparation method is also discussed, as well as possible posttreatments. The most extensive part of this subchapter is dedicated to polymeric SRNF membranes, as these are most abundant in literature, but ceramic and mixed matrix membranes are also discussed. Lastly, commercially available SRNF membranes are mentioned.
