以氮化硼粉末为导电填料，研制成功了导热硅橡胶弹性体导热垫。研究了填料含量和粒径对硅橡胶导热性能和力学性能的影响。结果表明，在相同的总填料含量下，与具有单一粒径的每种氮化硼相比，以优选的重量比使用具有三种不同粒径的混杂氮化硼赋予硅橡胶更好的导热性。此外，扫描电子显微镜、差示扫描量热仪、热重分析仪等，的形态，固化行为，热稳定性，和热膨胀系数（CTE）的硅橡胶复合材料的表征。Polym.比较器：28：23-28，2007.© 2007年塑料工程师协会
Thermally conductive silicone rubber used as elastomeric thermal pad is successfully developed with boron nitride powder as conductive filler. The effects of content and particle size of filler on the thermal conductivity and mechanical property of silicone rubber are investigated. The results indicate that the use of hybrid boron nitride with three different particle sizes at a preferable weight ratio gives silicone rubber better thermal conductivity compared with each boron nitride with single particle size at the same total filler content. Furthermore, scanning electron microscopy, differential scanning calorimeter, thermogravimetric, etc., are used to characterize the morphology, curing behavior, thermal stability, and coefficient of thermal expansion (CTE) of the silicone rubber composites.
