A key challenge in this field is contact angle hysteresis, caused by interfacial adhesion and frictional forces, which pin droplets and impede their mobility. To overcome this, we introduced a crack-mediated capillary bridging strategy that enables the efficient capture and directional transport of microdroplets. This approach utilizes a stretchable elastomeric substrate engineered with precision to incorporate island-like microstructures. Upon application of longitudinal tensile stress, the substrate undergoes controlled fracture, yielding densely packed, directionally oriented surface cracks. These fissures induce localized capillary forces of significant magnitude, effectively counteracting adhesion-induced resistance and facilitating programmable droplet motion. To validate the practical utility of this platform, experiments were conducted to capture airborne pathogenic agents, demonstrating a 14.2-fold enhancement in enrichment efficiency relative to conventional flat surfaces. These findings highlight the versatility of the proposed mechanism, offering promising avenues for advancing technologies in biosensing, pollutant analysis, and related interdisciplinary fields. The integration of fracture mechanics with capillary-driven fluid dynamics presented herein establishes a foundational framework for next-generation microfluidic systems.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"69 9","pages":"5827 - 5838"},"PeriodicalIF":7.7,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40843-026-4175-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148962099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The degradation mechanisms in scalable processing are dissected, highlighting the critical role of precursor ink design, where solute purity, ink aging, and solvent engineering collectively govern film uniformity and reproducibility. The exacerbation of intrinsic instabilities under scalable processing is analyzed through crystal and compositional design, defect generation and passivation, and ion migration in large-area devices. Stable device architectures suitable for scalable manufacturing are explored, including comparisons between n-i-p and p-i-n configurations and advancements in charge transport layers.

In this work, aramid nanofiber/carbon nanotube (ANF/CNT) aerogel fibers, integrating passive thermal insulation and active solar heating, were prepared by wet-spinning and ambient-pressure drying (APD). The incorporation of CNT and Ca²⁺ into ANF aerogel fibers generates abundant physical and chemical crosslinking points, strengthening the nanofiber network’s skeleton, and thereby reducing the structural collapse during APD with only 8.9% shrinkage. Thus, the synthesized ANF/CNT aerogel textiles demonstrated low thermal conductivity (33.8–40.4 mW/(m K)) and thermal insulation ability from −196 to 400 °C. More importantly, the photothermal effect of CNT enables active solar heating of aerogel fibers, effectively supplementing their thermal insulation, and allowing them to withstand extremely cold environments. In real tests, the synergistic effect of passive insulation and active heating improved the skin temperature by up to 5.9 °C, much higher than 1.6 °C obtained solely for passive insulation.
