摘要
用旋转涂覆法在石英衬底上涂覆单壁碳纳米管(SWCNT)和聚甲基丙烯酸甲酯(PMMA)溶液,恒温干燥后形成SWCNT薄膜。利用扫描电子显微镜(SEM)观测SWCNT的分布情况,研究了不同溶度、不同旋转速度对成膜的影响,用红外光谱仪测试薄膜试样的线性透过率,结果表明这种薄膜可用作可饱和吸收体。
we coat single -walled carbon nanotubes (SWCNT) and polymethylmethacrylate (PMMA) so- lution in quartz substrate by using rotation coating, which forms SWCNT film After drying on constant temperature. Using scanning'electron microscopy (SEM) observes the distribution of SWCNT, and re- searching the influence of the film, which the different solubility and rotating speed arouse, Using Infrared spectrometer tests the linear transmission of the sample films. The experimental results show that this kind of film fits to be used for saturable absorber.
