摘要：为了实现同步防护脉冲激光和连续波或准连续波激光的攻击,人们在过去几十年间已经投入了大量的人力和物力来研发高性能光限幅材料.石墨烯、过渡金属硫化物、黑磷等二维纳米材料拥有许多优异独特的性质,激发了全世界的广泛研究兴趣.本文简要回顾了基于石墨烯、黑磷、过渡金属硫化物和钙钛矿等最具代表性的二维材料及其有机/高分子衍生物在激光防护领域中的研究进展、存在的亟待解决的关键科学问题和未来的发展趋势.为了充分利用这些二维纳米材料的优点,人们可以使用功能小分子或聚合物与它们进行共混掺杂,制备复杂的多相材料体系,也可以将可溶性的有机/高分子共价功能化的二维纳米材料掺杂于高分子基质中形成主客体复合材料,这些制备方法有助于促进或提高整个体系的光限幅能力.总而言之,一个优化的复杂的多组份纳米材料体系能极大地增强光限幅器件的性能和适应性.此外,开展二维纳米材料和它们的衍生物在不同固体基质中展现出来的光物理和光子性质研究,将有助于在分子水平上实现对这些纳米材料的改性.
To achieve simultaneous protection against both pulsed and continuous wave(CW) or quasi-CW lasers,significant research effort has been devoted to the state-of-the-art optical limiting(OL) materials and processes in an attempt to achieve some measures of protection against such laser beams in the past decades. Twodimensional(2D) nanomaterials with a lot of unique properties, including graphene, transition metal dichalcogenides, black phosphorus and others, have aroused the extensive research interest of many researchers.In this review paper, we describe systematically the OL mechanisms and the recent achievements in the 2D nanomaterials and their organic/polymeric derivatives for laser protection. In an effort to sustain the advantage of 2D nanomaterials, one can not only introduce the functional molecules or polymers to blend with them to form a complex multi-phase material system, but also embed the soluble 2D nanosheets covalently functionalized with organic/polymeric materials in a polymer host to form host-guest composite materials that are expected to improve the OL performance of the whole system. All in all, an optimized complex multicomponent nanomaterial system enormously enhances the performance and applicability of OL devices. In addition, the fundamental studies of the photophysical and photonic properties of 2D nanomaterials and their derivatives in various solid hosts are of significance for modifying the nanomaterials at a molecular level.
