This review comprehensively delineates recent breakthroughs in surface modification strategies for inorganic fillers, emphasizing their pivotal role in advancing the performance of cable insulation material. The dispersion homogeneity and interfacial compatibility of inorganic fillers within cable insulation material matrices are identified as critical determinants of composite functionality. Physical modification techniques, leveraging non-covalent interactions such as surfactant adsorption and polymer encapsulation, mitigate particle aggregation and enhance dispersion. Chemical approaches, including coupling agent functionalization and graft polymerization, establish covalent interfaces to fortify filler-matrix adhesion. Notably, the emergence of dynamic reversible chemistry—encompassing stimuli-responsive covalent bonds (e.g., Diels-Alder adducts, boronate esters) and supramolecular interactions (e.g., hydrogen bonding, metal-ligand coordination)—has revolutionized composite design. These adaptive interfaces enable self-healing, stress relaxation, and reprocessability, addressing longstanding challenges in high-filler-loading systems. This work critically evaluates the mechanisms, efficacy, and applications of these methodologies while charting future research trajectories toward multifunctional, sustainable cable composites.

摘要

This review comprehensively delineates recent breakthroughs in surface modification strategies for inorganic fillers, emphasizing their pivotal role in advancing the performance of cable insulation material. The dispersion homogeneity and interfacial compatibility of inorganic fillers within cable insulation material matrices are identified as critical determinants of composite functionality. Physical modification techniques, leveraging non-covalent interactions such as surfactant adsorption and polymer encapsulation, mitigate particle aggregation and enhance dispersion. Chemical approaches, including coupling agent functionalization and graft polymerization, establish covalent interfaces to fortify filler-matrix adhesion. Notably, the emergence of dynamic reversible chemistry—encompassing stimuli-responsive covalent bonds (e.g., Diels-Alder adducts, boronate esters) and supramolecular interactions (e.g., hydrogen bonding, metal-ligand coordination)—has revolutionized composite design. These adaptive interfaces enable self-healing, stress relaxation, and reprocessability, addressing longstanding challenges in high-filler-loading systems. This work critically evaluates the mechanisms, efficacy, and applications of these methodologies while charting future research trajectories toward multifunctional, sustainable cable composites.
