“…Neither appreciable TOC nor protein was detected on the modified membrane surface, which is in accordance with the finding that the modified membrane enhances the anti-biosorption property. Some previous research has also reported the anti-fouling property of CS-associated membranes for organic foulants (Boributh et al, 2009;Ghiggi et al, 2017;Xia et al, 2018). A decrease of EPS and protein mass on the membrane surface by CS modification in a membrane bioreactor was also reported by Wang et al (2010a).…”

“…However, in the present study, most of the active amino groups are thought to have covalently reacted with PDA layer via Schiff-base/Michael-addition reactions (Luo et al, 2017), leading to an insufficient number of functional amino groups. Another possible reason is that amino groups are reported to present antimicrobial property under acidic condition, while natural water is a weakly basic environment (Xia et al, 2018;Zhang et al, 2014). This suggests the importance of using real water when investigating the applicability of CSassociated products in wastewater treatment processes.…”

Ordered porous membranes have wide and important application prospects in the fields of filtration, separation, catalysis, biomedicine, etc., and have attracted growing interest in the field of material science. Among diverse membrane preparation approaches, breath pattern method has been widely concerned due to its simplicity in the preparation, ease in tuning the structure/property and functionality of formed membranes, and broad utility for various polymers. With the development of material design, the application spectrum of breath figure membrane has been greatly expanded. However, since the pore morphology of porous membrane is influenced by many factors, the controlling mechanism of normalization has not been clear yet. In this paper, the research progress of film-forming materials in recent years is reviewed, and the correlation between pore formation and pore morphology is discussed in details. This information will provide a systematic and in-depth perspective for research in this filed and an important guideline for the preparation of the ordered porous films with divergent applications.

“…In membrane technology, the most important point to be considered is control over the structure and properties of membranes . Because membrane production is a very sensitive process, it depends on the operating conditions, such as the thermodynamic and kinetic factors of phase inversion . Additives have been widely used to control membrane morphology and tune the pore size, as they affect the phase‐inversion process.…”

A series of amphiphilic graft copolymers of poly (vinylidene fluoride‐co‐chlorotrifluoroethylene)‐g‐poly(2‐vinyl pyridine), P (VDF‐co‐CTFE)‐g‐P2VP, with different degrees of P2VP grafting (from 26.3 to 45.6 wt%) was synthesized via one‐pot atom transfer radical polymerization (ATRP). The amphiphilic properties of P (VDF‐co‐CTFE)‐g‐P2VP graft copolymers allowed itself to self‐assemble into nanoscale structures. P (VDF‐co‐CTFE)‐g‐P2VP graft copolymers were introduced into neat P (VDF‐co‐CTFE) as additives to form blending membranes. When two different solvents, N‐methyl‐2‐pyrrolidone (NMP) and dimethylformamide (DMF), were used, specific organized crystalline structures were observed only in the NMP systems. P (VDF‐co‐CTFE)‐g‐P2VP played a pivotal role in controlling the morphology and pore structure of membranes. The water flux of the membranes increased from 57.2 to 310.1 L m−2 h−1 bar−1 with an increase in the PVDF‐co‐CTFE‐g‐P2VP loading (from 0 to 30 wt%) due to increased porosity and hydrophilicity. The flux recovery ratio (FRR) increased from 67.03% to 87.18%, and the irreversible fouling (Rir) decreased from 32.97% to 12.82%. Moreover, the pure gas permeance of the membranes with respect to N2 was as high as 6.2 × 104 GPU (1 GPU = 10–6 cm3[STP]/[s cm2 cmHg]), indicating their possible use as a porous polymer support for gas separation applications.
