The development of membrane science plays a fundamental role in harvesting osmotic power, which is considered future clean and renewable energy source. However, the existing designs cannot handle low conversion efficiency power density. Theory has predicted that Janus with ionic diode-type current would be most efficient material. Therefore, rectified transportation hypersaline environment (the salt concentration at least 0.5 M sea) highly desired, but it still remains challenge. Here, we...
The design and fabrication of a robust nanoporous membrane in large scale is still challenge fundamental importance for practical applications. Here, three/two-dimensional polymer/graphene oxide heterogeneous constructed via the self-assembly approach by chemically designing charge-density-tunable ionomer with uniform pore size. To obtain polymer that maintains high mechanical strength promotes multifunctionality, we designed series amphiphilic copolymers introducing positively charged...
Abstract The membrane-based reverse electrodialysis (RED) technique has a fundamental role in harvesting clean and sustainable osmotic energy existing the salinity gradient. However, current designs of membranes cannot cope with high output power density robustness. Here, we construct sulfonated poly (ether ether ketone) (SPEEK) nanochannel membrane numerous nanochannels for generator. parallel space charges show excellent cation-selectivity, which could further be improved by adjusting...
Traditional optical organic vapor sensors with solvatochromic shift mechanisms have lower sensitivity due to weak intermolecular interactions. Here, we report a general strategy prepare higher sensor through polymeric swelling-induced variation of fluorescent intensity. We combine one-dimensional structures and aggregation-induced emission (AIE) molecules together form polymer/AIE microwires array as sensor. The prepared based on different commercial polymers can successfully classify...
A series of novel wholly aromatic sulfonated poly(arylene ether) copolymers containing sulfonic acid groups on the pendants [SC-SPAE, i.e., side-chain-type ether)] were prepared by direct copolymerization monomer [sodium 4-(4-(2,6-difluorobenzoyl)phenoxy) benzenesufonate (SDFBS)], 4,4'-dichlorodiphenyl sulfone (DCDPS), and 4,4'-dihydroxyldiphenylether (DHDPE). The sulfonate degree (DS) was readily controlled adjusting feed ratio SDFBS to DCDPS. Structures confirmed FT-IR NMR. Tough flexible...
A novel semicrystalline poly(ether ketone) (PEK)-based proton exchange membrane (semi-SPEK-x) has been developed. Through a one-step sulfonation and hydrolysis, ketimine) precursor transforms into PEK ion-conducting groups are introduced. With an ion-exchange capacity ranging from 1.49 to 2.00 mequiv g-1, the semi-SPEK-x polymers exhibit feature in both dry hydrated states. Owing domains inside polymer, obtained exhibits low water uptake volume swelling ratio. More importantly, structure...
Abstract A fast and highly efficient approach for the synthesis of hyperbranched poly(aryl ether ketone)s (HPAEKs) via polycondensation 2 BB′ monomers is described. Commercially available hydroquinone (HQ, monomer) easily synthesized 2,4′,6‐trifluorobenzophenone (TF, were thermally polycondensed to prepared fluoro‐ or phenolic‐terminated HPAEKs with K CO 3 Na as catalysts. During reaction, fluorine at 4′‐position TF reacts rapidly phenolic group HQ, forming predominantly dimers some other...
A new difluoride monomer containing electron-rich tetraphenylmethane was designed and synthesized. Based on this along with 4,4′-(hexafluoroisopropylidene)diphenol (6FBPA) 4,4′-difluorobenzophenone (DFB), a series of tetra-sulfonated poly(aryl ether ketone)s (TS-PAEK-x) were prepared by nucleophilic polycondensation, followed sulfonation reaction using chlorosulfonic acid. Tough, flexible, transparent membranes obtained solvent casing. These ion exchange capacity (IEC) values ranging from...

To obtain anion exchange membranes with both high ionic conductivity and good dimensional stability, a series of side-chain-type poly(arylene ether sulfone)s (PAES-QDTPM-x) were designed synthesized. Quaternary ammonium (QA) groups densely aggregated grafted onto the main chain via flexible hydrophobic spacers. Well-defined microphase separation was confirmed by small-angle X-ray scattering.
