The lightweight and high-strength functional nanocomposites are important in many practical applications. Natural biomaterials with excellent mechanical properties provide inspiration for improving the performance of composite materials. Previous studies have usually focused on the bionic design of the material's microstructure, sometimes overlooking the importance of the interphase in the nanocomposite system. In this Perspective, we will focus on the construction and control of the interphase in confined space and the connection between the interphase and the macroscopic properties of the materials. We shall survey the current understanding of the critical size of the interphase and discuss the general rules of interphase formation. We hope to raise awareness of the interphase concept and encourage more experimental and simulation studies on this subject, with the aim of an optimal design and controllable preparation of polymer nanocomposite materials.
轻质且高强度的功能纳米复合材料在许多实际应用中都很重要。具有优异机械性能的天然生物材料为改善复合材料的性能提供了灵感。以往的研究通常集中在材料微观结构的仿生设计上,有时忽略了纳米复合材料体系中界面相的重要性。在这篇观点文章中,我们将聚焦于受限空间内界面相的构建与调控以及界面相与材料宏观性能之间的联系。我们将综述目前对界面相临界尺寸的认识,并讨论界面相形成的一般规律。我们希望提高对界面相概念的认识,并鼓励更多关于该主题的实验和模拟研究,以期实现聚合物纳米复合材料的优化设计和可控制备。
