In this work, we synthesized a pair of AIEgens, designated as D- and L-TA-TPE, as dopants by utilizing tartaric acid and tetraphenylethylene. These AIEgens were incorporated as dopants into nematic liquid crystal polymer network films. The resulting films exhibited |glum| values of about 7.0 × 10–3, which can be attributed to the chiral conformations of these two AIEgens. For the AIEgen-doped cholesteric liquid crystal polymer network (CLCN) films, due to the selective Bragg reflection of the CLCN films, the |glum| values reached about 0.7. When composite films incorporating both fluorescent and CLCN layers were examined, the |glum| values reached about 1.6. The |glum| value increased with increasing CLCN film thickness. AIEgen-doped CLCN patterns were prepared by using a photomask or through screen printing. Based on the selective Bragg reflection and the handedness of the CPL, distinct images were observed through the left- and right-handed circular polarizers. Therefore, these patterns are potentially applied for decoration and anticounterfeiting.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 6","pages":"4029–4037 4029–4037"},"PeriodicalIF":4.4,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713983","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}

First, manganese sulfate (MnSO4) was oxidized to manganese dioxide (MnO2) microspheres with a diameter of 1.5–3.5 μm by catalysis of Ag+. Subsequently, polyaniline (PANI) grew in situ on the surface of MnO2 by the dilute solution method, using MnO2 as a self-degraded template in an acidic environment. The MnO2 was gradually reduced to Mn2+ because MnO2 acted as both an oxidant and a template for the polymerization of aniline, resulting in the formation of PANI microspheres with a hollow urchin-like structure. The as-prepared PANI, with its high specific surface area and porous properties, was considered a potential material for surface–interface chemical energy storage. Therefore, the specific capacitance of the hollow urchin-like PANI electrode could reach 531 ± 35 F/g at 5 mV/s, and the loss of specific capacitance was 41.0% when the current density increased from 1 to 10 A/g. Further analysis of the charge storage mechanism of the hollow urchin-like PANI electrode revealed that the electrode was controlled by slow kinetics, indicating that the electrode reaction was mainly controlled by the Faradaic intercalation process inside the active material. A symmetric supercapacitor device was also assembled using hollow urchin-like PANI microsphere electrodes, and the maximum energy density was about 17.92 Wh/kg at a power density of 500 W/kg.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 6","pages":"3544–3554 3544–3554"},"PeriodicalIF":4.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713942","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}

Specimens with varying layer thicknesses were fabricated by using a vat photopolymerization (VPP) multimaterial 3D printing process, and tensile tests were conducted to analyze the impact of thickness on the interfacial interaction and overall tensile strength. The experimental results show that reducing the layer thickness of the specimen to 0.2 mm significantly enhances the tensile strength due to improved interfacial bonding and material synergy. The finite element model of the transition region with the equivalent interfacial layer is established based on the microscopic morphology at the interface. Finite element analysis confirmed the experimental results, showing that reducing the layer thickness is beneficial for enhancing tensile strength in bimaterial structures.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 6","pages":"3935–3944 3935–3944"},"PeriodicalIF":4.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714173","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}

However, the incorporation of high stretchability, self-healing ability, toughness, and rapid adhesion into supersoft elastomers remains a formidable challenge. We synthesized an elastomer by the one-step photoinitiated copolymerization of commercially available acrylate monomers. The elastomer exhibited strain-reinforcing behavior, and its Young’s modulus was as low as 28.7 kPa. Because of the cooperation of soft and hard phases and hierarchical dynamic interactions, such as dipole–dipole interactions and hydrogen bonds, the elastomer possesses high stretchability (2815% elongation), rapid recovery (3 min), high crack resistance, and self-healing abilities. Notably, the elastomer exhibited rapid (contact time: 3 s), repeatable, and tough adhesion on various substrates in both air and underwater environments. In addition, the elastomer-based sensor detected human motion and handwriting. Overall, this work provides a simple strategy for synthesizing a multifunctional supersoft elastomer, which could be used in supersoft electronic devices.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 6","pages":"3588–3600 3588–3600"},"PeriodicalIF":4.4,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143713943","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 effect of the polymeric nature on the ionic conductivity was investigated. All polymer electrolytes exhibit an electrochemical stability of up to 4 V vs Li+/Li. This is extended to 4.3 V vs Li+/Li in polymer-containing methyl sulfonium groups, which possess the highest ionic conductivity (2·10–4 S cm–1 at 70 °C) and lowest plating–stripping overpotentials (≈0.1 V vs Li+/Li). However, polymer electrolytes containing thioether groups show not only high ionic conductivity but also oxidation in sulfoxide/sulfone between 4 and 4.5 V vs Li+/Li.

However, the high water content leads to inadequate antifreezing capability, severely restricting their application in cold environments. Here, an interpenetrating dual-network hydrogel with intrinsic antifreezing property was prepared by introducing silicone-containing imidazolium ionic liquid [SiM]Cl into an acrylic acid gel system. The introduction of silicone composition increases the fracture strength of the hydrogel by 157% to 0.62 MPa. Notably, the existence of ionic liquid [SiM]Cl greatly enhances the hydrogel’s low-temperature resistance, offering it a freezing point as low as −42.9 °C and a breaking elongation of 650% even at −20 °C. The hydrogel has a conductivity of 2.46 mS/cm and shows excellent linear strain-sensing behavior. Flexible sensors fabricated using this hydrogel demonstrate sensitive and responsive performance to human movements, and the array sensors produced through three-dimensional printing technology can accurately reflect the distribution of force and deformation. Furthermore, the hydrogel exhibits favorable pH sensitivity and inhibits the growth of Escherichia coli and Staphylococcus aureus in more than 99%.

SPEEK membranes were sulfonated using concentrated sulfuric acid (98%), introducing sulfonic acid (−SO3H) groups to enhance proton conductivity. To mitigate chemical degradation while maintaining conductivity, Ce(III)-benzene dicarboxylic acid metal–organic frameworks (Ce-MOFs) were incorporated. These Ce-MOFs scavenge radicals, improving the membrane’s durability and stability. Comprehensive analysis of the physicochemical, thermal, and mechanical properties showed that Ce-MOF addition enhanced conductivity and reduced degradation.

Three copolymer systems with different PVIm-TFSI chain lengths are analyzed, revealing that longer chains (430 kDa) enhance both particle dispersion and molar conductivity by forming well-connected corona layers, while other shorter chains (170 and 97 kDa) result in sparse strings and aggregated structures, respectively, and they exhibit lower conductivity. Potentiostatic polarization experiments show that the PVIM-TFSI chains rearrange and polarize irreversibly under applied electric fieds and this effect enhances ion conductivity. The polarization response of the copolymer hybrid indicates that PMMA grafts limit the polarization, and the PVIm-TFSI rearrangement in the copolymer occurs at long times. These findings underscore the critical importance of polymer hybrid structures in optimizing ionic conductivity, providing practical insights for applications in electroactive actuators, biomedical devices, wearable sensors, and electrochemical devices, such as capacitors and batteries.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 6","pages":"3853–3862 3853–3862"},"PeriodicalIF":4.4,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714126","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}

However, the influence of composition in host–guest systems has rarely been explored. Therefore, this study investigates composition-driven structural modulation in the st-PMMA/C60 complex system. Tuning the encapsulation ratio (E-ratio) of C60 not only regulates the accumulation of C60s molecules within the st-PMMA supramolecular helices but also modulates the composition of the st-PMMA/C60 helical bundles in the semicrystalline morphology. Variations in these hierarchical structures subsequently affect the vapochromism of the st-PMMA/C60 complex. At low E-ratios, isolated C60s molecules within the st-PMMA helices do not trigger a vapochromic response to aromatic volatile organic compounds (VOCs). At a moderate E-ratio of 15 wt %, the st-PMMA/C60 complex forms optimal hierarchical structures, allowing aromatic VOCs to efficiently intercalate into the st-PMMA/C60 helices and perturb the π-conjugation of C60s. However, at the maximum E-ratio, the st-PMMA/C60 complex loses its vapochromic response since the fully occupied supramolecular helices no longer encapsulate aromatic VOCs. Furthermore, the application of electrospinning to fabricate complex fibers increases the surface area, thereby improving the vapochromic response. Thus, this study highlights that hierarchical structures and vapochromic performance can be modulated by tuning the composition of host–guest systems.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 6","pages":"3863–3871 3863–3871"},"PeriodicalIF":4.4,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsapm.5c00084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
