Summary: Aromatic polysulfides and polysulfones are important sulfur-containing polymers with diverse applications. In this study, novel poly(arylene sulfide)s were synthesized in high yields through a metal-free, highly regioselective, one-pot reaction. The resulting polymers were soluble in common solvents. Controlled incorporation of functional groups was achieved by post-modification reactions. The oxidation of the poly(arylene sulfide)s produced poly(arylene sulfoxide)s and poly(arylene sulfones) with high selectivity, and heating resulted in the formation of nanofoams with homogeneous pore distribution.

Summary: Metal nanoparticles, particularly palladium nanoparticles (Pd NPs), can be effectively controlled and stabilized by iptycene-containing poly(arylene ether)s (PAEs). The PAEs not only limit the growth of Pd NPs but also facilitate the efficient transport of analytes, making them excellent sensory materials for hydrogen gas detection under ambient conditions. Strategies such as presorting SWCNTs with pentiptycene-containing poly(p-phenylene ethynylene)s (PPEs) and thermal annealing further enhance the chemiresistive performance.

Summary: In this work, a grafted polyamide 6 with quasi-block structure was used as a compatibilizer for an immiscible PVDF/PA6 blend, and its effects on the morphology, crystallization behavior, mechanical properties, and surface resistance of the blend were systematically investigated. It was found that the compatibilizer had a favorable effect on the blend, improving its morphology and mechanical properties, and providing surface conductivity. Differential scanning calorimetry and wide-angle X-ray diffractometry results revealed different effects of the compatibilizer on the crystallization behavior of PVDF and PA6.

Summary: In this work, a triketoenamine based dynamic covalent network was developed, which allows for easy construction of highly crosslinked and chemically reprocessable networks. The resulting polymer monoliths have high mechanical properties and can be recycled through aqueous solution-mediated monomer-network-monomer cycling. Furthermore, a catalyst-free and low-temperature reprogrammable covalent adaptable network was achieved. This design concept can be applied to the development of other novel vitrimers with high repressibility and recyclability, and contributes to the future design of sustainable polymers with minimal environmental impact.

Summary: A facile strategy was developed to achieve heterogeneous and high-efficiency photocatalytic dehalogenation by tuning the exciton binding energy of conjugated microporous polymers. The integration of acceptors into the polymer scaffolds effectively minimized the exciton binding energy, suppressed charge carrier recombination, and facilitated charge transfer. The designed CMP-CSU11 exhibited superior photocatalytic dehalogenation efficiency, surpassing state-of-the-art catalysts and enabling a broad scope of substrates with excellent recyclability. This work provides an effective strategy to develop task-specific heterogeneous photocatalysts based on intramolecular charge transfer engineering.

Summary: Triazine-based covalent organic frameworks functionalized by thiol and thioether (COFS-CH3/COFS-SH) were designed as a platform for specific binding with mercury ions based on Hard-Soft-Acid-Base theory. The COFS-CH3-modified carbon paste electrode exhibited exceptional performance (detection limit of 0.01 ppb; linear range of 0.1 to 1.0 ppb) and repeatability for electrochemical detection of trace mercury, even in real water samples. This innovative approach showcases the potential of covalent organic frameworks (COFs) for highly sensitive and selective detection of target analytes.

Summary: In this study, three fluoroalkyl trimethoxysilane (FATMS) additives with different chain lengths were incorporated into a two-component polyurethane clearcoat to improve its hydrophobic durability. The coatings modified with FATMS maintained their surface hydrophobicity under various conditions, but quickly lost it when exposed to both UV irradiation and/or high temperature with water. The results suggest that the FATMS route is more suitable for indoor applications at room temperature.

Summary: Green flame retardants have garnered attention for their environmental friendliness, but current options fall short in achieving high flame retardancy for flammable polymers and maintaining environmental protection. This study takes a two-pronged approach to address flame retardants and the flame-retardant process. An eco-friendly bio-based synergistic flame retardant (PAU), synthesized using phytic acid (PA) and urea (U), is used to create a flame retardant coating that can be directly applied to any surface shape using polydopamine as an adhesive. The resulting EPS-PAU exhibits excellent flame retardancy, smoke suppression, and light weight while only slightly increasing the density.
