| 摘 要： | 由于含有偶氮苯染料侧基,聚(氨酯-酰亚胺)(PUI)对532nm的光具有较强的吸收.采用该波长的可见偏振脉冲激光(Nd∶YAG激光器的倍频输出),在PUI薄膜表面制备了激光诱导周期性表面微结构(LIPSS).研究了染料引入方式以及染料侧基含量对微结构形成过程的影响,讨论了入射角、激光脉冲数、激光脉宽等激光辐射条件对LIPSS形成过程以及对微结构形貌和周期性的影响.

| Abstract: | Poly(urethane-imide) (PUI) greatly absorbs the visible light of 532 nm because it contains azobenzene side groups. For the first time, laser-induced periodic surface structures (LIPSS) were generated on PUI films with a linearly polarized laser of 532 nm, the second harmonic generation of an Nd∶YAG laser. The absorption of the molecular chain was necessary to form LIPSS and the increase of the content of the azobenzene side groups accelerated the appearance of LIPSS. The direction of LIPSS was parallel to the polarization direction of the laser beam and the periodicity was near the wavelength used. The influence of the laser parameters, including the incidence angle, the number of laser pulse and the length of laser pulse on the configuration and the periodicity of LIPSS was studied. The obtained surface pattern was observed by atomic force microscope. |
