Three dimensional (3D) image recording on photopolymer film was explored using a mixture of s-triazine diepoxy (SEP) and ethylene glycol phenyl ether acrylate (PA) as a monomer to induce cationic and radical polymerization during the holographic recording. The photopolymer films were sensitive to a visible light source and polymerized upon excitation with a visible laser. 3D image was recorded on the photopolymer film by holographic recording using a 491 nm laser. The film containing a molecular composite of SEP and PA showed high diffraction efficiency via dual photo polymerization. Within 10 min of recording the image formation was vivid. In this way 3D screw and a letter image with large viewing angle were obtained onto the photopolymer film. The images were stable for longer than 3 month at RT and 5 hr at 85 degrees C, when read by a visible light.
利用均三嗪二环氧(SEP)和乙二醇苯基醚丙烯酸酯(PA)的混合物作为单体,探索在光聚合物薄膜上进行三维(3D)图像记录,以便在全息记录过程中引发阳离子和自由基聚合反应。该光聚合物薄膜对可见光源敏感,用可见激光激发时会发生聚合反应。使用491 nm激光通过全息记录在光聚合物薄膜上记录3D图像。含有SEP和PA分子复合物的薄膜通过双重光聚合显示出高衍射效率。在记录的10分钟内,图像形成清晰。通过这种方式,在光聚合物薄膜上获得了具有大视角的3D螺旋和字母图像。当用可见光读取时,这些图像在室温下稳定超过3个月,在85摄氏度下稳定5小时。
