中文摘要： 近年来，成像探测设备的防护成为了激光防护领域研究的重点，也是国家发展的迫切需求。激光防护技术发展的基础和前提是具有高的稳定性、快速的响应时间、高的线性透过率、性能优异的材料。有机非线性光学材料具有响应速度快、线性透过率高、防护波段宽等特点，然而低的稳定性制约了其发展；液晶材料具有稳定性高、透明性好的特点，但是慢的响应时间阻碍了其发展。将有机非线性光学材料与液晶材料复合将能够满足实际的需求。本项目主要是针对激光防护技术的发展需求，围绕成像探测设备防护这一主要目标，从原理分析出发，设计合成出稳定快速响应的有机非线性光学-液晶（本项目拟定石墨烯-液晶）复合型激光防护材料，为激光防护技术的发展奠定重要的材料基础。该研究是材料、物理、化学等多学科交叉领域，具有重要的研究意义和应用前景。

英文摘要： Recently, the protection for the image detectors is the main issue in the laser protection field, which is also one of the most important requirements for a nation. The foundation and premise of the laser protection material is their good stability, rapid response time and high linear transmittance. Organic optical nonlinear materials, which possess rapid response time, high linear transmittance and broad protective bands, are regarded as the promising materials. However, the organic optical nonlinear materials suffered from their intrinsic poor stabilities and in turn limited their developments. Meanwhile, liquid crystal materials show good stability and high transparency yet with slow response. So the design of the combination of organic optical nonlinear materials with liquid crystals could be a good solution to meet the requirements for high performance laser protection materials. In this proposal, we will design and synthesize organic optical nonlinear-liquid crystal (graphene-liquid crystal) complex and characterize their properties. This is very important for achieving high performance in laser protective materials and will accelerate the development of these materials in industry. We intend to believe that this study covers the multidisciplinary fields of material sciences, physics and chemistry, and it
