“…According to the GPC results, the weight fraction of the PS block was 63%. Assuming that the bulk densities of PMMA and PS are 1.18 g cm À3 and 1.06 g cm À3 , respectively, 47,48 and a soluble PS shell. We found that the selective/common solvent ratio was very important to stabilize the self-assembled nanostructure during the subsequent hypercrosslinking process.…”

“…Researchers also have successfully deprotected poly(methyl methacrylate‐ r ‐trimethylsilyl)prop‐2‐ynyl methacrylate)‐ b ‐poly(4‐bromostyrene) (P(MMA‐ r ‐TMSPYMA)‐PBrS) block polymers to form poly(methyl methacrylate‐ r ‐propargyl methacrylate)‐ b ‐poly(4‐bromostyrene) (P(MMA‐ r ‐PgMA)‐PBrS) prior to solvent annealing without sacrificing the block polymer's capacity to self‐assemble into cylindrical domains. This process resulted in thin films with an alkyne‐functionalized pore wall that can be further modified by alkyne/azide click chemistry for applications such as biosensing and cell‐adhesion controlling . Another example of this transformative capability is detailed in a report regarding the fabrication of membranes from a poly(isoprene‐ b ‐styrene‐ b‐N , N ‐dimethylacrylamide) (PI‐PS‐PDMA) triblock polymer.…”

Nanoporous membranes based on self‐assembled block polymer precursors are an emerging class of promising separation, purification, and sensing devices due to the ability of researchers to control the nanostructure and chemistry of these multifunctional materials and devices. In fact, modern polymer chemistry provides techniques for the facile, controlled synthesis of the block polymers that constitute these devices. These designer macromolecules, in turn, can then self‐assemble into functional nanostructures depending upon the chemical identity of the synthesized block polymers and the thin film fabrication methods employed. After fabrication, these nanoporous membranes offer a highly tunable platform for applications that require high throughput, high surface area, homogeneous pore size, and varying material properties. And, with these readily tunable chemical and structural properties, block polymer membranes will allow for significant improvements in myriad applications. In this Review, we summarize the key advances, with a specific emphasis on the previous 5 years of work, that have allowed block polymer‐based membranes to reach their current level of technology. Furthermore, we project how these state‐of‐art, self‐assembled block polymer membrane technologies can be utilized in present‐day and future application arenas. In this way, we aim to demonstrate that the rigorous work performed on block polymer‐based membranes has laid a strong foundation that will allow these macromolecular systems to: (1) be major avenues of fundamental scientific research and (2) be parlayed into transferable technologies for the betterment of society in the imminent future. © 2014 Wiley Periodicals, Inc.

“…Recent studies have been focused on membranes equipped with a highdensity of functional groups amenable to several of these reaction mechanisms. [126][127][128][129][130][131] The thiol-ene mechanism demonstrates the flexibility associated with these approaches. In one study, the covalent linkage is realized by using membranes that contain reactive thiol groups, such as polystyrene-b-poly(4-vinylpyridine)-b-poly(propylene sulfide) (PS-P4VP-PPS) to attach the dye tetramethyl rhodamine-5 to the membrane surface.…”

Fit-for-purpose block polymer membranes molecularly engineered for water treatment

Continued stresses on fresh water supplies necessitate the utilization of non-traditional resources to meet the growing global water demand. Desalination and hybrid membrane processes are capable of treating non-traditional water sources to the levels demanded by users. Specifically, desalination can produce potable water from seawater, and hybrid processes have the potential to recover valuable resources from wastewater while producing water of a sufficient quality for target applications. Despite the demonstrated successes of these processes, state-of-the-art membranes suffer from limitations that hinder the widespread adoption of these water treatment technologies. In this review, we discuss nanoporous membranes derived from self-assembled block polymer precursors for the purposes of water treatment. Due to their well-defined nanostructures, myriad chemical functionalities, and the ability to molecularly-engineer these properties rationally, block polymer membranes have the potential to advance water treatment technologies. We focus on block polymer-based efforts to: (1) nanomanufacture large areas of highperformance membranes; (2) reduce the characteristic pore size and push membranes into the reverse osmosis regime; and (3) design and implement multifunctional pore wall chemistries that enable solute-specific separations based on steric, electrostatic, and chemical affinity interactions. The use of molecular dynamics simulations to guide block polymer membrane design is also discussed because its ability to systematically examine the available design space is critical for rapidly translating fundamental understanding to water treatment applications. Thus, we offer a full review regarding the computational and experimental approaches taken in this arena to date while also providing insights into the future outlook of this emerging technology.
