In this study,menthol was used as the core material,while β-cyclodextrin (β-CD) and its metal-organic framework derivative sodium β-cyclodextrin metal-organic framework (Na-β-CD-MOF) were employed as wall materials.Two inclusion complexes,menthol/β-CD and menthol/Na-β-CD-MOF,were prepared via the coprecipitation method and the mixed grinding method,respectively,with the optimal preparation conditions determined.The complexes were characterized by Fourier-Transform Infrared Spectroscopy (FT-IR),Scanning Electron Microscopy (SEM),X-ray Powder Diffraction (XRD),and Thermogravimetric Analysis (TGA).Furthermore,the sustained-release properties of the inclusion complexes at different temperatures were investigated using ultraviolet-visible spectrophotometry (UV-Vis).The results showed that the encapsulation efficiency of menthol/Na-β-CD-MOF reached 76.63%.Characterization data confirmed that menthol was successfully loaded,and its thermal stability was significantly enhanced after encapsulation.Notably,menthol/Na-β-CD-MOF exhibited excellent sustained-release performance,with its release mechanism better fitted by the Weibull model,indicating a complex release process.These findings demonstrate that loading menthol into Na-β-CD-MOF can effectively improve its stability.
