Abstract Aiming at the requirements of the spacecraft interface materials with high thermal conductivity, insulation property and low migration characte-ristics, based on the molecular chain entanglement theory,the self-made long-chain alkyl modified polysiloxane(AMS) and fluorinated polysiloxane(FPS) were prepared as matrix,and spherical aluminum nitride and flake boron nitride were used as thermal conductive fillers to prepare the thermal conductive grease. Through compounding the particle size of fillers with different particle sizes, exerting the synergistic effect of fillers with different morphologies and modifying the surface of the fillers, the thermal conductivity, the volume resistance and the breakdown voltage of the thermal conductive grease can reach 2.51 W/(m·K), 3.1×10¹⁵ Ω·cm and 10.1 kV·mm^-1. Based on the results of the migration test of thermal conductive grease, made from the self-made modified silicone oil with similar viscosity, of which the surface tension and contact angle test were carried out, it can be concluded that the oil migration characteristics of the thermal conductive grease is related to the contact angle of the base oil on the test panel. Increasing the molecular chain entanglement of silicone oil and improving the contact angle of the base oil on the coated surface can effectively reduce the migration of thermal conductive grease.
