Over the past decades, the development of high performance lightweight polymer nanocomposites and, in particular, of epoxy nanocomposites has become one the greatest challenges in material science. The ultimate goal of epoxy nanocomposites is to extrapolate the exceptional intrinsic properties of the nanoparticles to the bulk matrix. However, in spite of the efforts, this objective is still to be attained at commercially attractive scales. Key aspects to achieve this are ultimately the full understanding of network structure, the dispersion degree of the nanoparticles, the interfacial adhesion at the phase boundaries and the control of the localization and orientation of the nanoparticles in the epoxy system. In this Personal Account, we critically discuss the state of the art and evaluate the strategies to overcome these barriers.
在过去的几十年中,高性能轻质聚合物纳米复合材料的发展,尤其是环氧树脂纳米复合材料的发展,已成为材料科学领域最大的挑战之一。环氧树脂纳米复合材料的最终目标是将纳米粒子的优异固有特性外推到基体中。然而,尽管付出了努力,这一目标仍有待在商业上有吸引力的规模上实现。实现这一目标的关键方面最终是对网络结构、纳米粒子的分散程度、相界面的界面附着力以及对纳米粒子在环氧树脂体系中的定位和取向的控制的充分理解。在这篇个人述评中,我们批判性地讨论了现状,并评估了克服这些障碍的策略。
