Abstract	The thermo–mechanical behaviour of a Zirconia-Polyimide-ZIF-8 composite coating is examined in this study, with a specific focus on electric vehicle battery thermal management applications. Effective thermo-mechanical properties were derived using the Maxwell–Eucken model and the Rule of Mixtures for a 1:1:1 weight fraction blend. A cuboidal coating geometry of 100 mm × 100 mm × 10 mm was subjected to a hot surface temperature of 300°C and a convective cold boundary at 20°C with a forced convection coefficient of 20 W/m²·K. Steady-state coupled thermal and structural analyses were conducted in ANSYS Workbench 2026 R1. The composite produced a lower cold-surface temperature and reduced thermal stress relative to monolithic zirconia, while exhibiting greater deformation and strain - collectively reflecting improved thermal insulation alongside enhanced stress relaxation capability.
