4种三维打印材料的太赫兹光谱特性检测与分析
|
摘要
对常用的4种三维(3D)打印材料进行了太赫兹光谱检测与分析。实验结果表明:4种3D打印材料在0.20～2.60 THz范围内差异明显,其中3D打印聚碳酸酯材料对太赫兹光的透过率最高;4种材料的折射率在1.45～1.65之间,光敏树脂的折射率最大,在1.62左右;4种材料的介电常数实部在2.20～2.75之间,虚部在0.05～0.35之间;从吸收谱上看,4种材料都没有吸收峰并且吸收较小。该研究为利用3D打印材料制作太赫兹器件的材料选取提供了重要的参考。
Herein, terahertz spectra of four kinds of commonly used three-dimensional(3 D) printing materials are detected and analyzed. Experiments show that these printing materials have obvious differences in the range of 0.20-2.60 THz. The transmittance of 3 D printing polycarbonate measured in terahertz is highest. The refractive index of the four materials ranges from 1.45 to 1.65, and the refractive index of the photosensitive resin is the highest, which is approximately 1.62. The real and imaginary parts of the dielectric constant of these materials range from 2.20 to 2.75 and from 0.05 to 0.35, respectively. From the viewpoint of the absorption spectra, there are no absorption peaks among the four materials. This study lays the foundation for the selection of materials for 3 D printed terahertz devices.
