Insulated silicone/alumina (Al₂O₃) composites with high thermal stability and thermal conductivity were fabricated, in which the silicone resin was fabricated by a hydrolysis and condensation reaction with triethoxysilane (MTES), dimethyldiethoxysilane (DMDES) and phenyltrimethoxysilane (PhTMS). When the Al₂O₃ loading was 80 wt.%, the composite had only a 1.2% weight loss at 390°C. When the volume ratio of the 10 μm Al₂O₃ powder to 0.5 μm Al₂O₃ powder was controlled at 7:3, the silicone resin-based composite had thermal conductivity of 1.18 W m⁻¹ K⁻¹, which is 6.2 times as high as that of the pure silicone resin. Furthermore, the silicone/Al₂O₃ composite had dielectric strength of 87.5 kV mm⁻¹.

制备了具有高热稳定性和导热性的绝缘硅/氧化铝（Al ₂ O ₃）复合材料，其中硅树脂是通过与三乙氧基硅烷（MTES），二甲基二乙氧基硅烷（DMDES）和苯基三甲氧基硅烷（PhTMS）水解和缩合反应制得的。当Al ₂ O _3的负载量为80重量％时，该复合材料在390℃的重量损失仅为1.2％。当将10μm的Al ₂ O ₃粉末与0.5μm的Al ₂ O ₃粉末的体积比控制为7：3时，基于有机硅树脂的复合材料的热导率为1.18W m ^-1  K ^-1，是纯有机硅树脂的6.2倍。此外，有机硅/ Al ₂ O ₃复合材料的介电强度为87.5kV mm ^-1。
