Alumina/polymer composites are conventional thermal interface materials widely used for heat dissipation. However, the interfacial resistance (ITR) dominates conductivity (TC) of these composites, presenting a critical challenge. This study introduces erythritol as an innovative bridge to effectively reduce ITR by selectively locating it at interfaces among alumina (Al2O3) particles. Through straightforward preparation method, was positioned Al2O3 particles, followed impregnation poly(dimethylsiloxane) (PDMS) into filler gaps. The resulting Al2O3/erythritol/PDMS composite demonstrated 3.12 W·m-1·K-1 content 4.16 wt % and 53.7 vol %. Minor usage brings 34.4% enhancement compared with Al2O3/PDMS composites. Additionally, shows potential switch due erythritol's phase change properties. approach, which emphasizes fluid-state processing bridging, presents promising new strategy improving ceramic-filled polymer
