| Popis: | 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. |
