摘要

This study constructed a yam mucin composed of polysaccharides and proteins)-modified two-dimensional nickel-benzene−1,4-dicarboxylate metal-organic framework (2D Ni-BDC) nanocomposite via freeze-drying, leveraging the exceptional lubrication properties of yam mucus. Yam mucin was successfully extracted using hot water, followed by spectroscopic analysis and tribological evaluation of its lubrication performance. The structure and composition of the mucin-modified 2D Ni-BDC nanocomposite were comprehensively characterized through multiple techniques, enabling the preparation of mucin-modified 2D Ni-BDC-stabilized Pickering emulsions (Mucin-2D Ni-BDC-PK) with varying nanocomposite contents. Properties of these emulsions were systematically investigated as a function of nanocomposite addition, and their tribological performance was evaluated across different formulations. Results demonstrated that Mucin-2D Ni-BDC-PK emulsions reduced the average friction coefficient and wear rate by 73.1 and 71.69% respectively compared to pure water.
