Forward osmosis (FO) technology, characterized by high energy efficiency and low fouling propensity, holds considerable potential in desalination and wastewater reclamation. Nevertheless, the tortuous microporous structure of conventional support layers induces severe internal concentration polarization (ICP), limiting performance enhancement and further application of FO membranes. Here, we report the fabrication of 3D-printing support layers featuring through-pore structures, followed by integrating PES-COOH separation layers to develop a novel PES-COOH-TFC FO membrane. The through-pore architecture of 3D-printing support layers endows PES-COOH-TFC FO membranes with an ultra-low structural parameter, effectively mitigating the detrimental influence of ICP on membrane permeability. Moreover, surface segregation within the ultrathin PES-COOH separation layer promotes carboxyl enrichment on the membrane surface, ensuring superior rejection for the salt solutes. The optimal PES-COOH-TFC FO membrane achieved a water flux of 9.6 L m −2 h −1 and a reverse salt flux of 6.3 mmol m −2 h −1 when assessed using 2 M NaCl draw solution, corresponding to a superior reverse flux selectivity of 1523.8 ± 132.6 L mol −1 . This study transcends conventional structural design by introducing a strategy that leverages high-precision 3D printing technology to optimize FO membrane performance, offering a novel paradigm for the fabrication of advanced separation membranes.

Bismaleimide (BMI) resin is characterized by a high degree of cross-linking. However, its application is limited due to inadequate toughness. In this research, a series of thermoplastic reactive poly(arylene ether sulfone) (rPES-PPIs) resins with different propenyl contents were designed and used to toughen the N,N′-(4,4’-diphenylmethane) bismaleimide (BDM)/diallyl bisphenol A (DABPA) system. The study systematically examined the thermal stability, impact resistance, flexural strength, and fracture surface characteristics of both the BDM/DABPA system and the rPES-PPIs/BDM/DABPA blends. The findings indicated that the blend containing 10 phr of rPES-PPIs achieved an unnotched impact strength of 21.23 kJ/m2, which is a 220.21% increase compared to the unmodified system, while the flexural strength reached a maximum increase of 38.80% over the unmodified system. Dynamic mechanical analysis (DMA) also revealed an increase in the glass transition temperature (Tg) of the blends. Additionally, the system exhibited a relatively low curing activation energy of 18.25 kJ/mol, which facilitates the curing process. These results suggest that rPES-PPIs can greatly enhance the toughness of cured BMI resin without compromising thermal properties, and a related toughening mechanism is proposed.

Conventional toughening of bismaleimide (BMI) resin with linear thermoplastic faces a critical compromise: enhanced toughness often compromises thermal properties and elevates melt viscosity, severely limitations for their application in extreme environments. To overcome this long-standing challenge, a novel strategy was pioneered by designing and synthesizing a unique class of hyperbranched poly(carbazole-type bisphthalazinone sulfone)s (h-PCBPSs) with tailored reactive groups (propenyl or allyl), with the trifunctional monomer 4,4′-(9H-carbazole-2,7-diyl)bis(phthalazin-1(2H)-one) (CZ-BDHPZ) employed as the building block via a two-step procedure for the modification of BMI resin. h-PCBPSs exhibited high thermal resistance, with glass transition temperatures ( T g ) ranging from 308 to 355°C. The rheological behavior of the h-PCBPSs/BMI blends was characterized. The temperature range corresponding to the processing window, defined by a viscosity below 0.2 Pa·s, was broadened up to 140.1-185.5°C. The formation mechanisms of sea-island, single-phase, and star-shaped morphologies were elucidated, and the effects of these three distinct morphological structures on the thermal and mechanical properties of the BMI were systematically analyzed. The T g , unnotched impact strength, and flexural strength reached 293°C, 33.5 kJ/m², and 190 MPa, respectively. Compared with the cured product of the neat BMI, these values increased by 5.4%, 196.5%, and 36.7%, respectively. The thermo-oxidative aging resistance mechanism of BMI modified by h-PCBPS-A was elucidated. After 7 days of aging at 250°C, the impact strength retention rate and flexural strength retention rate of h-PCBPS-A-10phr/BMI reached 36.3% and 88.9%, respectively. This work provides a new design strategy for BMI toughening agents and promotes the application of BMI resin in extreme environments.

Membrane distillation (MD), a promising thermal desalination technology, faces a critical challenge in its practical deployment: membrane wetting induced by low-surface-tension contaminants, which compromises separation efficacy and long-term operational stability. To address this challenge, we conceptualize and fabricate a photo-responsive composite nanofiber membrane endowed with an intrinsic self-cleaning capability to overcome this limitation. This MoO 3 @ZIF-8/PAES-CF 3 composite membrane is architected with a hierarchical roughness and engineered to exhibit dynamic, light-gated anti-wetting behavior. The strategic integration of hydrophobic and photoactive MoO 3 @ZIF-8 nanoparticles, within a fluorinated poly (arylene ether sulfone) (PAES-CF 3 ) matrix via electrospinning yields a robust, photoactive interfacial structure that concomitantly enhances surface hydrophobicity and mechanical integrity. In direct contact membrane distillation (DCMD), the optimized membrane demonstrates exceptional performance, achieving a water flux of 21.3 L·m −2 ·h −1 while maintaining a salt rejection rate exceeding 99.9%. Crucially, the membrane shows excellent resistance to wetting induced by sodium dodecyl sulfate (SDS) under light illumination, withstanding concentrations up to 0.15 mM. Moreover, under a feed solution containing 0.1 mM SDS, the membrane maintains stable operation for 24 h. This work presents a novel strategy for designing anti-wetting MD membranes, providing a foundation for the development of environmentally responsive and adaptive separation materials.

A series of poly (aryl ether sulfone) containing different contents of amino groups (ABPFx) were synthesized by nucleophilic polycondensation reaction. The ABPFx has excellent thermal resistance with the T g reaching 277 °C as well as maintains good mechanical and film-forming properties. Particularly, the ABPF10 membrane exhibits high gas permeability [P (H 2 ) = 22.24 Bar] and gas selectivity [α (H 2 /N 2 ) = 63.5]. Consequently, the ABPFx membranes have potential application value in the field of gas separation for hydrogen separation.

The inevitable membrane damage during the use of separation membrane seriously affects the separation and purification effects. Herein, we first synthesized a novel poly(aryl ether sulfone) material containing boronic acid groups (PES-H 2 BO 2 ) through molecular design, then PES-H 2 BO 2 ultrafiltration membrane was prepared via non-solvent induced phase inversion method. Further, the PES-H 2 BO 2 ultrafiltration membrane and polyvinyl alcohol (PVA) hydrogel were composited by hydrogen bonds and reversible boronate ester bonds between the two to fabricate a series of novel PVA hydrogel/PES-H 2 BO 2 composite ultrafiltration membranes. Through the ultrafiltration experiment of polyacrylamide (PAM) solution, the flux and retention rate changes of the composite ultrafiltration membrane in the initial stage, damage stage, self-healing stage, and stabilization stage were tested and analyzed. The results confirmed that the composite membrane has the ability to rapidly restore the flux and retention rate to the pre-breakage levels through a self-healing effect within 15 min after being damaged, demonstrating their outstanding self-healing characteristics. The design strategy of fabricating composite ultrafiltration membrane with excellent self-healing performance by forming hydrogen bond and reversible boronate ester bond between hydrogel and membrane matrix in this study provides a convenient and feasible way for the design and preparation of high-performance self-healing separation membranes.

The thermal degradation mechanism of POPESKs was determined investigated by TG-FTIR. The T g s of POPESKs range from 296 to 326 °C and the storage modulus retention is up to 46.1 % at 290 °C. POPESKs have good solubility in dichloroethane, chloroform, tetrachloroethane, N -methyl-2-pyrrolidone and pyridine, and exhibit good film-forming property. The tensile strength, tensile modulus, and tensile elongation of POPESK films are 85–96 MPa, 1.34–1.86 GPa, and 8.9–11.6 %, respectively. Meanwhile, the polymer films exhibit the high light transmittance of up to 83 % at 800 nm and its water contact angle are in the range of 82.3–94.3°. Its superior overall performance shows great potential in aerospace, petrochemical and energy applications.

Developing polymer-based organic afterglow materials with switchable ultralong organic phosphorescence (UOP) that are insensitive to moisture remains challenging. Herein, two organic luminogens, BBCC and BBCS, were synthesized by attaching 7H-benzo[c]carbazole (BBC) to benzophenone and diphenyl sulfone. These two emitters were employed as guest molecules and doped into epoxy polymers (EPs), which were constructed by in situ polymerization to achieve polymer materials BBCC-EP and BBCS-EP. It was found that BBCC-EP and BBCS-EP films exhibited significant photoactivated UOP properties. After light irradiation, they could produce a conspicuous organic afterglow with phosphorescence quantum yields and lifetimes up to 5.35% and 1.91 s, respectively. Meanwhile, BBCS-EP also presented photochromic characteristics. Upon thermal annealing, the UOP could be turned off, and the polymer films recovered to their pristine state, showing switchable organic afterglow. In addition, BBCC-EP and BBCS-EP displayed excellent water resistance and still produced obvious UOP after soaking in water for 4 weeks. Inspired by the unique photoactivated UOP and photochromic properties, BBCC and BBCS in the mixtures of diglycidyl ether of bisphenol A (DGEBA) and 1,3-propanediamine were employed as security inks for light-controlled multilevel anticounterfeiting. This work may provide helpful guidance for developing photostimuli-responsive polymer-based organic afterglow materials, especially those with stable UOP under ambient conditions.

High-performance polymers that are both high temperature resistant and soluble is significant for the development of high-tech fields. 4,4′-(Thiobis(4,1-phenylene))bis(phthalazin-1(2H)-one) (T-BDHPZ) monomer is synthesized by an efficient two-step method using inexpensive phenyl sulfide and phthalic anhydride as raw materials. A series of novel poly(bisphthalazinone thioether sulfone ketone)s (PBPTSKs) were synthesized via aromatic nucleophilic substitution polycondensation. The structures of PBPTSKs were characterized by NMR and FT-IR. These polymers have glass transition temperatures ( T g s ) in the range of 302–328 ℃, and are soluble in N -methyl-2-pyrrolidone (NMP), pyridine (Py) and 1,1,2,2-tetrachloroethane (TECT), and partially soluble in N , N -dimethylacetamide (DMAc), N , N -dimethylformamide (DMF), dichloromethane (DCM), trichloromethane (TCM) and pyridine. PBPTSK films were prepared by solution casting, and the average light transmittance from 400 to 800 nm of films are all over 70%. PBPTSK boards prepared by hot press molding have outstanding mechanical properties with the tensile strength and the flexural strength of 91–102 MPa and 123–135 MPa, respectively. PBPTSK boards also exhibit excellent high- and low-temperature resistance properties at 290 and −60c, respectively. Moreover, these polymers with bisphthalazinone thioether moiety have outstanding inherent flame retardancy, which pass the V-0 level of the UL-94 test. This provides opportunities to develop high-performance polymers that are both high temperature resistant and soluble, showing great prospects in frontier applications.

In this paper, sulfonated poly(arylene ether ketone sulfone)s containing fluorenyl groups (F-SPAEKS) were synthesized. MIL-101-NH 2 was prepared by hydrothermal reaction . The carboxyl group was modified to MIL-101-NH 2 by amidation reaction, then difunctional MIL-101-NH 2 was designed (MIL-101-NH 2 -COOH). The fillers of MIL-101-NH 2 and difunctional MIL-101-NH 2 -COOH were added into F-SPAEKS matrix to prepare the hybridized membranes, respectively. The structures and morphologies of MIL-101-NH 2 , MIL-101-NH 2 -COOH and hybridized membranes were characterized by SEM, FT-IR, 1 H NMR, XPS and XRD . Among these prepared hybridized membranes, FSMNC-4 (the weight percentage of MIL-101-NH 2 -COOH was 4%) had the highest proton conductivity (159.90 mS cm −1 at 80 °C). The proton conductivity of FSMNC-4 was 1.79 times higher than that of pure F-SPAEKS (89.30 mS cm −1 at 80 °C) and 1.25 times higher than that of FSMN-4 (the weight percentage of MIL-101-NH 2 was 4%) (127.55 mS cm −1 at 80 °C), respectively. Meanwhile, the increase of hydrophilic groups also resulted in the highest water absorption of FSMNC-4 (21.57% at 80 °C). The ionic cross-linked networks reduced the swelling ratio of the hybridized membranes. The swelling ratio of all hybridized membranes was lower than 10%. FSMNC-4 also had good thermal and oxidative stability . The open circuit voltage (OCV) and maximum power density of FSMNC-4 were 0.994 V and 466 mW/cm 2 , respectively. The above results indicated that FSMNC-4 had a promising potential to be applied in PEMFCs.

High energy density, high temperature, and low loss dielectric polymers have drawn increasing attention in research owing to their potential applications in power electronic and pulsed power devices. In this study, a new class of organo-soluble dipolar glass polymers (DGPs) are synthesized via polycondensation and post-functionalization of poly(aryl ether)s (PAEs) based on phenolphthalin. Due to the nonplanar backbone structure, the strongly dipolar side groups (-SO 2 CH 3 and -CH 2 CH 2 CN) can easily rotate in these PAEs. As a result, desirable physical properties are obtained: high dielectric constant (4.4–5.6), high glass transition temperature (155–180 °C), good mechanical property, and low dielectric loss (dissipation factor < 0.005). Among them, cyanolized poly(aryl ether nitrile) exhibit the highest discharged energy density of 8.6 J cm −3 at 650 MV m −1 and room temperature with a high discharged efficiency of 94.3%. At 100 °C, cyanolized poly(ether ether ketone) shows the highest discharged energy density of 7.3 J cm −3 at 600 MV m −1 with a discharged efficiency of 91%. Furthermore, these functionalized PAEs exhibit good mechanical toughness with a tensile strength at a break of 60-120 MPa and elongation at a break of ≈5%. Based on their thermal, mechanical, and dielectric properties, these phenolphthalin-based PAEs are promising for potential applications such as film capacitors.

One kind of promising anion exchange membrane (AEM) bPES(x/y)-Q based on block poly(ether sulfone)s with a rigid side-chain and high-density annular quaternary ammonium groups has been developed. Characteristically, the AEMs have high conductivities (62.3–98.7 mS cm−1) at low IECs (0.9–1.5 mequiv. g−1) due to their excellent microphase separation resulting from block copolymer structures, rigid side-chains and high-density ion moieties. Meanwhile, the AEMs have relatively good alkaline stability and oxidative stability because of their special chemical structures. Further investigation reveals that the AEMs show potential application in anion exchange membrane fuel cells, where the bPES(5/20)-MPy based single fuel cell shows the maximum power density of 164 mW cm−2.
