One of the major difficulties is the solid/solid contact between the electrode and the electrolyte, which is troublesome to efficiently construct during manufacturing. To overcome this problem, preliminary efforts have been made so far to incorporate SPEs as ion-conductive binders in electrodes, as reported in the literature. To further this concept, the present study examines in detail the rheological properties of aqueous graphite electrode slurries containing poly(ethylene oxide) (PEO)-based SPEs, which are critical for practical deployment but have not received much attention. The evaluations were conducted using flow curve, strain, and frequency sweep viscoelasticity, and step flow measurements. These evaluations demonstrate that the SPE-containing slurries exhibit practical feasibility with a shear-thinning and thixotropic nature. These properties resemble those of common battery slurries and are appropriate for manufacturing. The studies also suggest that viscosity and moduli can be controlled by optimizing the preparation procedure of the slurries as well as the SPE composition. Nevertheless, a slightly stronger tendency toward dilatancy and poor dispersion problems were identified, which may present challenges. The results demonstrate that the development of electrodes containing SPEs necessitates careful evaluation and optimization of the rheological properties of the slurries. The present study sheds significant light on the importance of specialized knowledge and techniques to obtain accurate and useful information on the non-Newtonian fluidity and viscoelasticity of battery electrode slurries containing SPE materials. We believe that the present feasibility study will contribute to advancing the concept of SPE-containing electrode slurries to the practical manufacturing level.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 8","pages":"4973–4981 4973–4981"},"PeriodicalIF":4.4,"publicationDate":"2025-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867606","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, its slow crystallization rate and low crystallinity limit its heat resistance, rendering it insufficient for many practical applications. In this study, heat-resistant tannic acid-epoxidized soybean oil (TA-ESO)/PLA composite fibers reinforced with TA-ESO microgel are successfully fabricated via melt spinning. The TA-ESO microgel functions as a physical cross-linker, establishing a cross-linked structure within the PLA matrix. The incorporation of TA-ESO microgel substantially influences the isothermal crystallinity of the TA-ESO/PLA composite and effectively reduces spherulite size. Moreover, the TA-ESO microgel enhances the mechanical properties of as-spun TA-ESO/PLA fibers, increasing tensile strength from 0.80 cN/dtex of pure PLA to approximately 1.00 cN/dtex. The hot-drawn process significantly improves both the mechanical properties and thermal stability of TA-ESO/PLA fibers.

However, in the complex environments of battlefields and disasters, in addition to the required CWA protection functionality, these materials must also possess physical protective properties, such as flame retardancy, thermal insulation, and breathability. Traditional Zr-MOF-loaded substrates, such as fibers, polyester films, and foams, face limitations like a low surface area, porosity, and poor breathability, hindering their multifunctional protection potential. Therefore, how to achieve a combination of chemical and physical protection remains a challenge.

The composite exhibits self-disinfection, flame retardation, heat insulation, comfort, and air/moisture permeability with a porous three-dimensional fiber network. It has a high MOF loading rate of 55.6%, achieving CEES and DMNP degradation rates of 98.5 and 99.3%, respectively, along with excellent chemical stability and reusability. Furthermore, the composite demonstrates strong mechanical properties (with a tensile stress reaching 223.4 kPa and a compressive stress of up to 318.5 kPa at 60% strain), along with flame retardancy, thermal insulation, breathability, moisture permeability, and comfort.

Plastic recycling, although a very prominent option, has its limitations by way of poor mechanical integrity of recycled plastic compared to virgin plastic, which severely limits the applications of this recycled plastic. To facilitate closed-loop recycling in thermoplastics, scientists have increasingly turned to dynamic covalent bonds (DCBs) as a potential solution. Incorporating DCB’s into commercially available plastics to convert them into vitrimers improves the mechanical integrity of plastics and preserves them during the recycling process. In this study, we convert acrylonitrile-butadiene-styrene (ABS) into vitrimers via reactive extrusion, which is a facile and industrially scalable method widely employed in the polymer industry. The vitrimerization process was carried out by cross-linking ABS with a commercially available polyepoxide resin, 4,4′-methylenebis(N,N-diglycidylaniline) (TGDDM). The vitrimers showed a significant improvement in the ultimate tensile strength (approximately 44%) and high retention of mechanical and thermal properties after three reprocessing runs. Additionally, the vitrimers showed good dimensional stability, good thermal stability, and fast stress relaxation at elevated temperatures.
