However, the energy absorption performance of these STF related materials is not fully exploited due to the low coupling efficiency between the STF and the structure. In this paper, the dynamic compressive behavior of STF filled star-shaped honeycombs (SSH) with significant negative Poisson's ratio (NPR) effect was studied using modified SHPB experiments and finite element (FE) simulations. The coupling mechanism between the NPR effect and the shear-thickening behavior of STF is analyzed. The dynamic mechanical performance of the STF-filled SSH (SSH-STF) under initial velocity impact and constant velocity compression loading, including stress distribution, energy dissipation, and coupling strength, is comprehensively analyzed. The results indicate that SSH-STF enhances energy absorption efficiency by the mutual extrusion effect of SSH and STF, which limits local deformation and modifies the unstable deformation mode of SSH, while also expanding the energy absorption region. The shear thickening effect of STF limits 82 % of the in-plane rotation behavior of SSH-STF unit cells compared to unfilled SSH under high-velocity impact, promoting uniform and sufficient contraction deformation across the unit cells, which enhances the mean crushing force by 253 %. Meanwhile, the shear thickening behavior of STF leads to faster stress transfer within SSH, significant enhancement of the local deformation stability and effectively increasing the critical impact velocity of the SSH-STF. In this paper, the significant enhancement of energy absorption performance of the STF-SSH composite provides valuable insights for the design of STF-filled auxetic honeycomb structures in practical applications.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"299 ","pages":"Article 112415"},"PeriodicalIF":12.7,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143685515","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}

In this study, we propose SUM-1(Zr), a two-dimensional layered MOF that effectively captures C₂H₂ molecules by utilizing electronegative oxygen as hydrogen bond donors and separates C₂H₂/CO₂ mixtures by competitive adsorption between C₂H₂ and CO₂ molecules. The adsorption capacity of SUM-1(Zr) for C₂H₂ was measured to be 3.07 mmol g⁻¹ at 298 K and 1 bar, with an IAST selectivity for C₂H₂/CO₂ reaching 3.33. Kinetic studies demonstrated faster diffusion rates of C₂H₂ and CO₂ molecules in hexagonal channels with larger pore sizes. The electronegative oxygen atoms and –NH molecules in SUM-1(Zr) create a favorable adsorption environment for the guest molecules, while the –NH moiety in SUM-1(Zr) is oriented towards the narrow triangular channels, and the wide hexagonal channels contains numerous electronegative oxygen atoms that act as hydrogen bond donors, selectively trapping C₂H₂ molecules. Theoretical calculations indicate that C₂H₂ prefers to adsorb near the oxygen atoms in the wide hexagonal channels, forming multiple hydrogen bonds with the oxygen atoms in the two adjacent parallel layers. It is worth noting that the binding energies of these two types of channels for C₂H₂ are significantly higher than those for CO₂, resulting in competitive adsorption between C₂H₂ and CO₂.

The inherent connection between the prepared thin film and substrate decreases the overall resistance and facilitates electron transfer across the interface. Also, the thin film porosity helps in effective ion diffusion between the electrode/electrolyte interface.
