聚合物纳米复合材料是其中填料在至少一个维度上小于100 nm的聚合物基质复合材料。这些复合材料表现出非常有趣的特性。聚合物纳米复合材料的一个定义特征是，与传统复合材料相比，填料的小尺寸导致界面面积的显著增加。该界面面积产生了显著体积分数的界面聚合物，其具有甚至在低负载下也不同于本体聚合物的性质。该界面区域的性质和结构尚未定量地知道，这对控制和预测聚合物纳米复合材料的性质提出了挑战。本文简要介绍了聚合物纳米复合材料，重点是界面区域的影响。
Polymer nanocomposites are polymer matrix composites in which the fillers are less than 100 nm in at least one dimension. These composites have exhibited extraordinarily interesting properties. A defining feature of polymer nanocomposites is that the small size of the fillers leads to a dramatic increase in interfacial area as compared to traditional composites. This interfacial area creates a significant volume fraction of interfacial polymer with properties different from the bulk polymer even at low loadings. The properties and structure of this interfacial region are not yet known quantitatively, presenting a challenge both for controlling and predicting the properties of polymer nanocomposites. This paper provides a brief overview of polymer nanocomposites with emphasis on the impact of the interfacial region.
