“…The reason may be that the adsorption sites in the SPENH-60 decrease with the increase of the number of cycles. [39] The results show that SPENH-60 adsorbent has good stability and regeneration performance, and has the potential for industrialized Li + separation.…”

“…However, after 7 consecutive adsorption-regeneration cycles, the loss of adsorption uptake was large and only achieved 80.71 % of the initial value. [39] Therefore, there is an urgent need to develop high-performance lithium adsorption materials with -SO 3 H groups. [40] Sulfonated polyarylene ether (SPEN) is a special polymer material with adjustable -SO 3 H groups.…”

In this paper, a series of sulfonated polyarylene ether nitriles copolymers (SPEN) with adjustable sulfonic acid groups are synthesized through nucleophilic substitution reaction. Then, the SPEN hollow fiber membrane (SPENH) adsorbents are successfully prepared by dry-wet phase conversion. Due to the increase of hydrophilic groups sulfonic acid (À SO 3 H) and increases surface roughness, the water contact angle of SPENH-60 is as low as 46.97°, and the wettability of SPENH adsorbent is improved. In addition, SPENH-60 adsorbent has a high porosity of 97.87 % and À SO 3 H groups (1.53 mmol g À 1 ), which shows an excellent Li + adsorption uptake of up to 20.54 mg⋅g À 1 . The adsorption kinetics of Li + follows the pseudo-second-order adsorption kinetic and the adsorption isotherm data conforms to the Langmuir model. The selectivity factors of Li + to Na + , K + , Ca 2 + and Mg 2 + are 5.019, 4.038, 2.726 and 48.348, respectively. After 10 times of adsorption-desorption cycles, the adsorption uptake decrease by only 4.3 %. Therefore, SPENH adsorbent has the potential to selectively separate and recycle Li + from brine.

“…An approach like this could be beneficial for sterilizing a polyHIPE-based filter as the inner surface of current N95 filters can have a warm, wet microclimate which can contribute to bacterial growth (a strategy that could also work for viral infections)[ 83 ]. Silver is an effective antibacterial agent and can be coated on the surface of a polystyrene sulfonate-based polyHIPE[ 84 ] or a polystyrene-based polyHIPE[ 85 ]. Alternatively, broad-spectrum antimicrobial activity can be obtained by iodine-releasing polyHIPEs made from kaolin-containing cross-linked PEG-NaAA-PEG polyHIPEs[ 86 ].…”

This review paper explores the potential of combining emulsion-based inks with additive manufacturing (AM) to produce filters for respiratory protective equipment (RPE) in the fight against viral and bacterial infections of the respiratory tract. The value of these filters has been highlighted by the current severe acute respiratory syndrome coronavirus-2 crisis where the importance of protective equipment for health care workers cannot be overstated. Three-dimensional (3D) printing of emulsions is an emerging technology built on a well-established field of emulsion templating to produce porous materials such as polymerized high internal phase emulsions (polyHIPEs). PolyHIPE-based porous polymers have tailorable porosity from the submicron to 100 s of μm. Advances in 3D printing technology enables the control of the bulk shape while a micron porosity is controlled independently by the emulsion-based ink. Herein, we present an overview of the current polyHIPE-based filter applications. Then, we discuss the current use of emulsion templating combined with stereolithography and extrusion-based AM technologies. The benefits and limitation of various AM techniques are discussed, as well as considerations for a scalable manufacture of a polyHIPE-based RPE.

“…Therefore, adsorption method is a preferred separation method for metal ions because of its simple, rapid, and high efficiency. PolyHIPEs with oxygen‐, nitrogen‐, and sulfur‐containing functional groups, or grafted with EDTA, aniline, pyridine, crown ether, or other organic compounds, have been successfully demonstrated effective in the adsorption separation of various metal ions, including Ag + [36], Cs + [129, 130], Li + [131–135], Rb + [130, 135], Cd 2+ [36, 136–138], Cu 2+ [36, 75,103, 138–143], Hg 2+ [144], Ni 2+ [98], Pb 2+ [72, 136, 142, 145], Sr 2+ [130, 135], Zn 2+ [143], Cr(IV) [146, 147], plutonium ions [148, 149], and rare‐earth metal ions (Ce 3+ , La 3+ ) [150] through direct adsorption or ion‐exchange process.…”

Polymerized high internal phase emulsions as highly porous adsorption materials have received increasing attention and wide applications in separation science in recent years due to their remarkable merits such as highly interconnected porosity, high permeability, good thermal and chemical stability, and tailorable chemistry. In this review, we attempt to introduce some strategies to utilize polymerized high internal phase emulsions for separation science, and highlight the recent advances made in the applications of polymerized high internal phase emulsions for diverse separation of small organic molecules, carbon dioxide, metal ions, proteins, and other interesting targets. Potential challenges and future perspectives for polymerized high internal phase emulsion research in the field of separation science are also speculated at the end of this review.
