研究了合成α-磷酸锆（α-ZrP）层状结构的环氧纳米复合材料的形貌和力学性能。由于α-ZrP具有高表面离子交换容量的特性，其层间表面易于修饰。α-ZrP结构呈层状粘土状，纵横比至少为100。剥落的状态已被证实使用直接透射电子显微镜观察样品的不同位置。α-ZrP添加量为1.9 vol %时，α-ZrP增强环氧纳米复合材料的拉伸模量提高了50%，屈服强度提高了10%。然而，经α-ZrP强化后，基体的延展性（断裂伸长率）急剧降低。讨论了α- zrp基环氧纳米复合材料的基本结构-性能关系。
The morphology and mechanical properties of epoxy nanocomposites based on synthetic α-zirconium phosphate (α-ZrP) layer structure have been investigated. The interlayer surfaces of α-ZrP can be easily modified because of its high surface ion exchange capacity characteristics. The α-ZrP structure is layered claylike and possesses aspect ratios of at least 100. The state of exfoliation has been confirmed using direct transmission electron microscopy observation at various locations of the sample. With an addition of only 1.9 vol % α-ZrP, the tensile modulus of the α-ZrP-reinforced epoxy nanocomposite is increased by 50%, and the yield strength improved by 10%. However, the ductility of the matrix (elongation at break) is drastically reduced after the α-ZrP reinforcement. The fundamental structure−property relationship of α-ZrP-based epoxy nanocomposite is discussed.
