摘要
合成了4种新型的金属酞菁化合物,并将其掺入聚合物聚甲基丙烯酸甲酯(PMMA)中,制备出金属酞菁/聚甲基丙烯酸甲酯复合材料及涂膜材料。通过对其进行紫外—可见光谱和反饱和吸收特性测试发现其具较好的反饱和吸收性能和较大的线性透过率。其中B/PMMA复合膜层材料可见光最大透过率大于70%,起始阈值127·1mJ/cm2,动态范围1·43,是很好的反饱和吸收材料。同时探讨了影响金属酞菁材料反饱和吸收性能因素。研究结果对多波段、高光密度、高透过率新一代激光防护材料的制备具有重要意义。
Four new types of metal phthalocyanine compounds were prepared. By mingling the compounds with the PMMA, composite materials and film coating materials of metal phthalocyanine/PMMA were prepared. The compounds were characterized in the UV-VIS spectra and the reverse saturable absorption measurements of the composite materials were performed. It is found that the compounds have good performance of reverse saturable absorption and good linear transmittance. The measured max transmittance of the composite film coating materials of B/PMMA is more than 70%, its initial threshold is 127.1 mJ/cm^2 and dynamic range is 1.43. All these characters show it is an excellent reverse saturable absorption material. This research has led to be helpful in preparing new anti-laser materials applicable to multiple wavelength, high optical density and having high trans-mittance.
