AI Technical Summary
Existing modification techniques cannot simultaneously achieve high insulation and high strength in high insulation materials. Traditional interface modification strategies have limited interfacial bonding strength, leading to performance degradation of materials under multi-field coupling conditions.
By constructing an interface with a topological interlocking structure, utilizing the nanopores on the surface of modified mica to form a geometric interlock with nylon 66 molecular chains, and combining it with glass fiber to construct a three-dimensional interlocking network, the material achieves high volume resistivity and high tensile strength.
A breakthrough has been achieved in the synergistic effect of high insulation (volume resistivity ≥1.5×10⁶ Ω·m) and high strength (tensile strength ≥220 MPa). The material exhibits excellent performance stability under extreme environments, meeting the needs of cutting-edge fields such as ultra-high voltage and deep-sea exploration.
