提出了一种基于包覆共掺杂结构金属纳米粒子偶氮染料复合物(MNPADC) 合成的新方法,可使偶氮染料甲基橙定向吸附于球形金属银纳米粒子表面形成染料对纳米粒子的包覆结构,再将具有该结构的掺杂剂掺于聚合物基质聚乙烯醇中,制备出MNPADC复合材料薄膜.紫外可见吸收光谱表明,该材料在波长为400~450 nm的波段具有良好的光吸收特性.热质量分析发现,其热学特性更适合于光存储的要求.实验结果表明,该材料的设计方法为改善有机光存储介质材料的热学性能提供了简便而有效的途径.
A new method based on the co-doped metal nanoparticles nanoparticle azo dye complex (MNPADC) was proposed, which can make the azo dye methyl orange adsorbed on the surface of spherical metal silver nanoparticles to form the dye-to-nanoparticle And then doping the dopant with the structure in the polymer matrix polyvinyl alcohol to prepare a MNPADC composite film.The UV-visible absorption spectrum shows that the material has a good wavelength band of 400-450 nm Optical absorption characteristics.The thermal analysis shows that the thermal properties are more suitable for optical storage.The experimental results show that the design method of the material provides a simple and effective way to improve the thermal performance of the organic optical storage medium material.
