While extensive research has been conducted on LHCEs, the molecular-level mechanisms by which antisolvents function remain partially elusive. This study employs a combination of spectroscopic analysis and computational methods to investigate the impact of the antisolvent 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether (TTE) on the solvation structures within carbonate-based LHCEs. Our results suggest that the incorporation of TTE modifies the Li⁺ solvation structure by decreasing the dimethyl carbonate (DMC) concentration and increasing the anion proportion in the solvation shell, thereby enhancing Li⁺ transport. Furthermore, two-dimensional infrared (2D IR) spectroscopy discloses that elevated TTE content cause the decrease of the inhomogeneous components of LHCEs, and limited spectral diffusion relaxation dynamics are related to the refined aggregates in higher TTE addition. Most notably, 2D IR spectroscopy enables the detection of the ultrafast dynamics within the solvation structure. Specifically, at higher TTE concentrations, there is a swift energy transfer between Li⁺-DMC and free DMC. The picosecond-scale disparity in energy transfer times implies a possible link to the effectiveness of Li⁺ transport. As such, this research deepens our comprehension of the role of antisolvents and provides novel insights into their influence on the microstructure of LHCEs.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"83 ","pages":"Pages 223-230"},"PeriodicalIF":21.1,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143601219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method allows precise printing of multiple materials and structures on large-area flexible/rigid and flat/curved substrates. The printed line width, confined by microarchitectural templates, reaches a high resolution of 300 nm. The microarchitecture topography is systematically investigated to optimize the wicking effects within the cross-scale templates. As a result, a phased-array antenna on a 1.25-meter-scale 3D surface can be fabricated in just 20 min due to the multi-directional parallel wicking occurring at multiple printing locations. Additionally, the printed circuits, embedded within and protected by the microarchitectural template, exhibit exceptional robustness by maintaining their initial resistance even after undergoing 600 cycles of an abrasion test. Furthermore, high-precise printing of commonly used functional nano-inks and graphics printing on arbitrarily curved substrates were also realized.

In this study, we propose a novel methodology that integrates electrophoretic assembly (electrophoretic deposition) and laser powder bed fusion additive manufacturing processes to create personalized, semipermeable, and biodegradable polymer/metal composite membranes suitable for guided bone regeneration applications. Specifically, we first designed a personalized porous Zn substrate using an adaptively unit-cell arrayed filling method, which achieved a complex and manufacturable curved surface shape while ensuring integrity of unit cells and uniform stress distribution. Subsequently, the Zn substrate was fabricated by laser powder bed fusion, and was utilized as both the bracing structure and the template for conformal electro-growth of chitosan/gelatin cryogel to obtain the desired polymer/metal composite membrane. This composite membrane allowed efficient nutrient transfer while inhibiting 100 % fibroblasts infiltration. As compared to Zn substate, coverage of conformal chitosan/gelatin cryogel enhanced mechanical properties and reduced the biodegradation rate of the membrane.
