In particular, inorganic materials with layered crystal structures, such as graphite, are a well-known category of solid lubricant. However, their structural designability is restricted because of their chemically stable nature, making it difficult to control their tribological characteristics. In this study, the solid lubricity of copper(<small>II</small>) benzene-1,4-dicarboxylate (CuBDC), a two-dimensional metal–organic framework (2D-MOF), was investigated as a new type of solid lubricant with structural diversity. The tribological measurements of powder-supported specimens revealed that CuBDC exhibited good lubrication properties comparable to those of typical solid lubricants, such as graphite and polytetrafluoroethylene. From the scanning electron microscopy observations of the worn surfaces of the CuBDC-supported specimen, the layered crystal structure of CuBDC effectively formed a smooth wear surface at the contact area. In contrast, specimens supporting copper(<small>II</small>) benzoate and copper(<small>II</small>) benzene-1,3,5-tricarboxylate, which have similar chemical natures as CuBDC, exhibited high frictional force, reflecting on the difference in their crystal structures. Furthermore, the transformation of the CuBDC crystal by thermal treatment, which afforded interlayer coordination bonds, increased the friction coefficient. These results suggest that the solid lubricity of CuBDC originates from its layered crystal structure. Thus, the 2D-MOFs with layered crystal structures are potential candidates for solid lubricants with good property tunability.</p>","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 2","pages":" 451-459"},"PeriodicalIF":0.0,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d4lf00267a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various polymer/HNT composites have been studied, but generally these composites have HNTs as a minor component. Here, we report novel polymer/HNT composites with high HNT content facilitated by strong hydrogen-bonding interactions between the polymer and HNTs. These composites with 50–75 wt% HNTs were prepared by <em>in situ</em> polymerization reactions of mixtures comprising HNTs, acrylic acid, triethylene glycol dimethacrylate, potassium persulfate, and water, followed by drying. The chemical structure of composites was verified by Fourier-transform infrared spectroscopy (FTIR). The high dispersity of HNTs in the poly(acrylic acid)-based matrix was demonstrated by scanning electron microscopy (SEM). Studies of mechanical properties illustrated greatly enhanced mechanical strength of the composites relative to the pure polymer matrix, with the highest flexural strength, microhardness, and ultimate tensile strength achieved for the composite with 66.7 wt% HNTs. Thus, the incorporation of high mass fractions of HNTs in a polymer matrix can offer potential benefits for applications requiring superior mechanical properties, in addition to other functions endowed by either HNTs or the polymer matrix. Differential scanning calorimetry (DSC) characterization did not show evidence of a glass transition in the polymer matrices of these composites, and thermogravimetric analysis (TGA) revealed increased thermal stability of the composites relative to the matrices. Swelling tests indicated that the swelling capacity is primarily determined by the amount of polymer present in the composite, and the presence of HNTs may facilitate mass transfer of water within the polymer matrix.</p>","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 2","pages":" 410-419"},"PeriodicalIF":0.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d4lf00356j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143594501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the vast adsorbent space, computational studies play a critically significant role in facilitating the discovery of potential candidates. However, large-scale computational deployment by conventional grand canonical Monte Carlo (GCMC) to identify optimal water adsorbents is challenging due to its extreme computation time and expense. In this work, a lattice GCMC method (LGCMC) with hierarchically constructed discretized interaction of host–guest and guest–guest driven by atomistic potentials was attempted to accurately and rapidly simulate the water adsorption performance of adsorbents using a coarse-grained Molinero water (mW) model. Nevertheless, given the monatomic nature of the mW model, leading to different phase behaviors in nanoscale confinement, a remarkable discrepancy in the primitive LGCMC-predicted isotherms, especially different step positions, compared with experiments was observed. Thus, a general correction strategy of water adsorption isotherm by tuning the saturation pressure was adopted. Taking metal–organic frameworks (MOFs) as examples, simulated water adsorption isotherms consistent with experimental results were obtained by the correction strategy using LGCMC. It is worth highlighting that the simulation of water adsorption in adsorbents by LGCMC can be accomplished within a few hours, which yields a significant acceleration of two to three orders of magnitude compared to conventional GCMC simulations. Therefore, the corrected LGCMC is a powerful tool to screen a huge number of adsorbents to facilitate the discovery of potential adsorbents for water adsorption-related applications, and this study provides microscopic insights into water adsorption mechanisms in porous adsorbents.</p>","PeriodicalId":101138,"journal":{"name":"RSC Applied Interfaces","volume":" 1","pages":" 230-242"},"PeriodicalIF":0.0,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/lf/d4lf00354c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
