Paraffin wax (PW) has significant potential for spacecraft thermal management, but low conductivity and leakage issues make it no longer sufficient the requirements of evolving control systems. Although free-state expanded graphite (EG) as a enhancer can ameliorate above problems, remains challenging to achieve higher (K) (>8 W/(m·K)) at filler contents below 10 wt.% mitigate problem. Two preparations thermally conductive shape-stabilized PW/EG composites, using pressure-induced method prefabricated skeleton method, were designed in this paper. The formed nanoscale porous structure by different methods, which enhanced capillary action between flake layers, improved adsorption encapsulation EG, alleviated latent heat phase-change materials (PCM) prepared two methods mentioned are 9.99 W/(m·K), 10.70 W/(m·K) 240.06 J/g, 231.67 respectively, EG loading wt.%, residual mass fraction was greater than 99% after 50 cycles high temperature. In addition, due excellent management capability PW/EG, operating temperature electronic components be stably maintained 68–71 °C about 15 min peak reduced least 23 when heating power is w. These provide novel cost-effective further improve
