Abstract

Smart materials hold great promises for many intrigue applications as they can exhibit chemical and physical responses to the applied external stimuli. This presentation will focus on smart nanostructured materials with responsive optical properties that can find applications in printing, sensing, anti-counterfeiting, signage, and display. In particular, we will discuss some of our latest advances in the development of novel chemical synthesis and assembly approaches for the fabrication of various nanostructured materials, and how to dynamically tune the optical properties of these materials by controlling the spatial arrangement and orientation of the nanoscale building blocks. By controlling the interaction between light and nanostructures, various optical properties such as diffraction, refraction, birefringence and electron resonance can be dynamically controlled to develop many new types of smart optical materials.

智能材料能对所受的外部刺激表现出化学和物理反应，因而在很多未来的设备中都有极大的应用前景。 本报告将重点介绍具有光学响应特性的智能纳米材料，其可用于印刷，传感，防伪，标志，和显示等很多方面。 我们将特别讨论我们在制造各种纳米结构材料的新型化学合成和组装方面的一些最新进展，介绍如何通过控制纳米级构件的空间排列及取向来动态调整这些材料的光学特性。通过控制光与纳米结构之间的相互作用，可以实现对衍射，折射，双折射和电子共振等很多光学性质进行调控，从而来开发出许多新型的智能光学材料。
