By systematically analyzing their molecular structure, (opto)electronic properties, photovoltaic performance, morphological analysis, and mechanical stability, this study reveals the profound influence of donor isomerism on material properties, relevant to organic electronic applications. In particular, NDI–L-NDT exhibits a lower bandgap attributed to its extended donor π-conjugation and nearly coplanar D–A conformation compared to NDI–A-NDT. NDI–A-NDT demonstrates superior photovoltaic performance due to its higher power conversion efficiency compared to its linear counterpart. Morphological studies based on molecular dynamics simulations reveal that films of both copolymers exhibit similar levels of crystallinity. However, NDI–L-NDT possesses greater thermal stability and mechanical flexibility, capable of withstanding up to 100% strain without cracking, attributed to its dynamic conformational adaptability, making it a promising candidate for flexible electronic applications.

With the increasing demand for lightweight and high-strength materials, the utilization of carbon fiber-reinforced polymers (CFRP) in these fields has grown. Given the promising potential of superhydrophobic surfaces in mitigating ice accumulation, the fabrication of such surfaces on CFRP substrates is of great importance. In this study, we fabricate hierarchical micro/nanostructures on CFRP substrates by integrating hydrophobic silica nanoparticles and a metal sieve template through a hot-pressing process. The resulting surface achieves exceptional superhydrophobicity with a static water contact angle of 155° and a sliding angle of 4° while conferring robust mechanical and chemical durability against abrasion and chemical etching. Static freezing experiments demonstrate the superior icing delay performance of the superhydrophobic CFRP surface through prolonging both the cooling time and the freezing time. Impacting droplets exhibit full rebound behavior within Weber numbers of 20–140 when the surface temperature is above −25 °C.

Hydrogels, being moist and soft materials, have generated great interest for their use in flexible electronics and sensing. Conventional hydrogels are brittle and show inadequate self-recovery and fatigue resistance, significantly restricting their application. Moreover, the water in the hydrogel freezes at subzero temperatures, limiting the use of devices in cold climates. The efficient adhesion of the hydrogels to diverse substrates is also essential for device applications. Creating a hydrogel with a favorable combination of properties, fast self-recovery, high stretchability, self-healing, antifreezing, and self-adhesive capabilities, alongside sufficient ionic conductivity, is challenging. We report herein physically cross-linked copolymer hydrogel AAm/ORn, based on poly(acrylamide-<i>co</i>-acryloyl ornithine). The optimized hydrogel showed high toughness (1.3 MJ m^–3), excellent stretchability (fracture strain: 3000%), fast self-recovery (within 35 s after tensile loading–unloading to 100% strain), and good adhesive strength to various substrates like plastic (3900 N/m²), glass (13,360 N/m²), and rubber (7870 N/m²). The ionically conducting hydrogel-based flexible resistive strain sensor demonstrated high strain sensitivity (GF value of 0.65 within the strain range of 400–800%) and can detect human limb movements. Synthesizing the hydrogel in the presence of LiCl (1 M) significantly improved the ionic conductivity (from 3.47 to 8.84 mS/cm at room temperature) and rendered the hydrogel antifreezing. The corresponding AAm/ORn/LiCl hydrogel maintained good conductivity (7.6 mS/cm) even at −15 °C. The flexible supercapacitor device fabricated with the AAm/ORn/LiCl hydrogel electrolyte, when operated at −15 °C, retained ∼50% of the specific capacitance displayed at room temperature (37.66 F/g). This work offers a simple strategy for making a high-performance hydrogel, which may be used in human motion sensors and flexible energy storage devices in cold environments.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 19","pages":"13037–13051"},"PeriodicalIF":4.7,"publicationDate":"2025-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145247733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gelation reaction, based on cross-end linking between maleimide- and thiol-terminated TetraPEGs, in the IL containing sodium bis(trifluoromethanesulfonyl)amide (NaTFSA) was investigated using rheological measurements and kinetic analysis. The gelation rate exhibited a strong dependence on the metal ion species (Na⁺ vs Li⁺): gelation occurred more slowly in the Na system than in the Li system, as characterized by the gelation time (<i>t</i>_gel) and apparent rate constant (<i>k</i>_gel′). The resulting TetraPEG ion gels showed excellent mechanical integrity even at a low polymer concentration (5 wt %), though the Na-based gels were mechanically weaker than their Li-based counterparts. A comprehensive structural analysis combining experimental and theoretical approaches revealed the molecular-level origin of this ion-specific behavior: (1) in IL solutions without PEG, Na⁺ is coordinated by three TFSA^– anions to form the anionic complex [Na(TFSA)₃]^2–; (2) in the presence of PEG, partial TFSA^– release enables the formation of PEG–Na⁺–TFSA^– ternary complexes with expanded polymer conformations; and (3) in contrast, Li⁺ preferentially coordinates with PEG, forming compact Li⁺–PEG complexes with contracted polymer chains. These distinct coordination modes result in different chain conformations, which in turn influence the mechanical performance of the ion gels through entropy-driven elasticity.

Nevertheless, the insufficient proton (H⁺) supply derived from the sluggish water oxidation limits the overall photocatalytic H₂O₂ production rate. Herein, two pyridyl-acetylene-based porous organic polymers with identical skeletal structures but distinct substituents, namely, CH₃-TEE-POP and NO₂-TEE-POP, were synthesized by varying the substituent at the meta-position of the pyridinic nitrogen. The substituent at the meta-position of the pyridinic nitrogen influences the interaction between the pyridinic nitrogen and H₂O molecules. Density functional theory analysis reveals that the interaction between the N atom in the CH₃-TEE-POP skeleton and H₂O molecules is stronger than that in NO₂-TEE-POP, resulting in a more significant weakening of the O–H bond in water molecules. The weakening of the O–H bond facilitates the 4-electron water oxidation reaction to generate H⁺ and O₂ and simultaneously promotes the consumption of holes, leading to an improvement in the overall photocatalytic efficiency. Consequently, CH₃-TEE-POP achieves an exceptional initial H₂O₂ production rate of 3183 μmol g_cat^–1 h^–1, outperforming that of NO₂-TEE-POP (1609 μmol g_cat^–1 h^–1).
