利用和频发生（SFG）显微成像方法进行低碳钢表面硫醇自组

Sum frequency generation imaging microscopy has been used to investigate a self-assembled monolayer of
an alkanethiol (octadecanethiol, ODT) on a mild steel surface. The images are used to analyze the orientation
of the alkanethiol monolayer and the distribution of orientational angles as well as defects in the film. The
results show that, on average, ODT forms an ordered monolayer on mild steel when compared to the same
monolayer on gold. However, the image analysis suggests that the distribution of tilt angles and conformational
defects is greater for ODT on a mild steel surface compared to ODT/Au. 表面和频光谱分析系统(SFG) PL2230系列高能量全固态锁模皮秒Nd:YAG激光器 Ekspla CARS 相干反斯托克斯拉曼显微光谱仪
