    Abstract: Bilayer platelet fillers are employed to compensate for a positive coefficient of thermal expansion (CTE) of an embedding polymeric material, or even to provide a composite structure having a negative CTE to eliminate or alleviate thermomechanical stress and/or delamination during thermal cycling. A bilayer platelet includes two joined layers having different CTEs. The CTE mismatch induces bending of the bilayer platelets, thereby causing cavities at temperatures lower than the joining temperature at which the bilayers are joined. The decrease in the volume of the polymeric material and the bilayer platelets at low temperatures is compensated by an accompanying increase in the volume of the cavities so that the composite structure has a temperature independent volume, a low net CTE, or even a negative CTE.

    Abstract translation: 双层血小板填料用于补偿嵌入聚合材料的正热膨胀系数（CTE），或甚至提供具有负CTE的复合结构以消除或减轻热机械应力和/或热循环期间的分层。 双层血小板包括具有不同CTE的两个接合层。 CTE不匹配引起双层片晶的弯曲，从而在低于双层结合的接合温度的温度下引起空腔。 聚合物材料和双层血小板在低温下体积的减少通过伴随空腔体积的增加来补偿，使得复合结构具有不依赖于温度的体积，低净CTE或甚至负的CTE。
