“…There are plenty of studies starring the TIPS method followed by a post-treatment imparting the membrane with antifouling properties, but very few exist, to our knowledge, in which only TIPS is used to induce phase separation of a polymer/antifouling material/diluent blend. In the period of time on which this survey focusses, we shall mention the work performed in Matsuyama’s group who entrapped a PEGylated copolymer in PVDF TIPS membranes in one step (hollow fibers) [ 365 ] as well as those of Xu et al [ 23 ] and Li et al [ 366 ], who used multi-wall carbon nanotube and nanoparticles of SiO 2 and GO, respectively, to fabricate PVDF membranes by TIPS (flat sheet). Regarding the former, the authors did not notice any significant effect of the copolymer on the membrane structure.…”

Membrane technology is an essential tool for water treatment and biomedical applications. Despite their extensive use in these fields, polymeric-based membranes still face several challenges, including instability, low mechanical strength, and propensity to fouling. The latter point has attracted the attention of numerous teams worldwide developing antifouling materials for membranes and interfaces. A convenient method to prepare antifouling membranes is via physical blending (or simply blending), which is a one-step method that consists of mixing the main matrix polymer and the antifouling material prior to casting and film formation by a phase inversion process. This review focuses on the recent development (past 10 years) of antifouling membranes via this method and uses different phase-inversion processes including liquid-induced phase separation, vapor induced phase separation, and thermally induced phase separation. Antifouling materials used in these recent studies including polymers, metals, ceramics, and carbon-based and porous nanomaterials are also surveyed. Furthermore, the assessment of antifouling properties and performances are extensively summarized. Finally, we conclude this review with a list of technical and scientific challenges that still need to be overcome to improve the functional properties and widen the range of applications of antifouling membranes prepared by blending modification.

“…[6][7][8] Some features in comparison with homopolymer membranes are the high porosity along with much narrower pore-size distribution, stimuli-response properties, betterdefined pore morphology, rich possibilities of functionalization, lower fouling, and surface roughness, versatility of morphology control, more appropriate surface chemistry and structuration. [6,[8][9][10] Therefore, application of BCP membranes could be extended to more efficient and promising separations, due to their superior final structures. [8,11] Notwithstanding these general advantages, there is still a need and opportunities for improving BCP membranes for other demanding applications, by overcoming their versatility limitations, for example, the lack of mechanical, chemical, thermal, and long-term stability.…”

Self-standing isoporous membranes based on amphiphilic block copolymers (BCPs) are an outstanding candidate for efficient separation processes. Such fascinating membranes have been generated through combining the BCP self-assembly (micro-phase separation) together with the classical non-solvent induced phase separation (macro-phase separation), known as SNIPS process. However, the controllability, reproducibility, and cost-effectiveness of the process along with the mechanism for pores generation are still challenging in the SNIPS strategy, especially when new BCP or conditions are utilized. It is mainly due to the narrow efficacy window of numerous variables influencing the desired structure formation. In this review, first, an overview of the one-step readily scalable SNIPS technique and the stepwise explanation of the process are given. Then the formation mechanism of SNIPS membranes, according to the related hypotheses and assumptions proposed on the basis of experimental evidence so far, is presented and discussed. As the main focus , governing factors in the SNIPS process which affect the preparation and structural characteristics of final membrane structures are entirely reviewed and interpreted. This review will help to have a better understanding of the connection between determinant factors and final membrane structure, which facilitates successful preparation of BCP membranes via SNIPS.

Passive warm‐keeping textiles could reduce carbon emissions by turning down indoor heating in winter. Polar bear hair exhibits a unique structure composed of a hollow core and an aligned porous shell, which extremely helps to resist heat transport. Great interest has arisen in the development of thermo‐insulating textiles with this biomimetic structure. In this work, cellular hollow fibers were made by a large‐scalable wet spinning‐foaming process. This efficient method achieved rapid formation of polar bear hair‐like fiber as well as facile turning properties of the fibers. The structure and properties of biomimetic fibers depended on the content of foaming agent. As‐prepared porous thermoplastic polyurethane (TPU)/polyacrylonitrile (PAN) composited fiber showed excellent ductility. The maximum tensile strength and breaking elongation was 4.31 MPa and 121%, respectively. The corresponding woven textile exhibited excellent thermal insulation properties even under deformation by compression or tension. The temperature difference across the thickness of textile was 17.9 and 34.9°C under a background temperature of 0 and 80°C, respectively. It may pave the way to fabricate new structure–function integrated fiber materials for warm‐keeping textiles.
