“…[21,32] Covalent functionalization of a BCP-derived nanopore surface has been pursued to tailor the nanopore permeability, as discussed in a recent review article. [41] One approach is to use intrinsic surface functional groups yielded as a result of nanopore formation, including the amidation/esterification of surface ÀCOOH groups on PS-b-PMMA-derived nanopores [47,60] and the quaternization of pyridyl groups on PS-b-P4VP-derived nanopores. [61] The more sophisticated approach is to use BCPs that are designed to offer nanopores with known surface functional groups (e.g., À COOH, alkene, À NH 2 ) at a controlled density upon the removal of the cylindrical domains.…”

Microphase separation of block copolymers (BCPs) has been extensively studied because it leads to the self-assembled formation of periodic structures controlled on the scale of tens of nanometers. In particular, BCP-derived cylindrical microdomains have attracted considerable interest for various applications owing to their well-defined shapes of uniform and tunable diameters. This focus review highlights recent efforts to apply BCP-derived monolithic films/membranes comprising cylindrical nanopores for chemical sensing and separations. The nanopores provide confined molecular pathways that exhibit enhanced selectivity based on steric, electrostatic, and chemical interactions, and thus, enable us to design unique electrochemical sensors and highly efficient separation membranes.

“…The cylindrical nanopores with tunable diameters, narrow pore diameter distributions, and chemical functionalization capabilities [41] will lead to the design of highly selective chemical sensing/separation media. The high porosity (20-30 %) will make high-flux separations possible, in contrast to TEPMs with relatively low porosity.…”

“…28,99 As detailed in some of the examples above, these chemical alterations can modify the physical properties of membranes fabricated from block polymers such that they display excellent size-selective separation abilities. In addition, the block polymer system can be modified using straightforward schemes for controlled properties that go beyond the size of the membrane pores.…”

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.

“…[1][2][3][4] A promising approach to nanoporous materials is based on the self-assembly of block copolymers. [5][6][7][8][9] Utilizing the nanosegregation of two covalently-connected, incompatible polymer blocks, nanoporous materials can be obtained with pore diameters down to 10 nm after selective phase removal. Inorganic nanoporous materials, like aluminosilicate structures known as zeolites, have pore sizes below 1 nm and are robust materials.…”

The development of a nanoporous material from a columnar liquid crystalline complex between a polymerizable benzoic acid derivative and a 1,3,5‐tris(1H‐benzo[d]imidazol‐2‐yl)benzene template molecule is described. The morphology of the liquid crystalline complex is retained upon polymerization and quantitative removal of the template molecule affords a nanoporous material with the same lattice parameters. The nanoporous material selectively binds cations from aqueous solution, with selectivity for sodium and potassium ions over lithium and barium ions, as shown with FT‐IR. Binding is also quantified gravimetrically with a quartz crystal microbalance with dissipation monitoring, a technique that is used for this purpose for the first time here.
