项目摘要
The purpose of this research is to actively control factors affecting the quality of the Langmuir fils, which we call "processing". It is essential to have in situ characterization techniques in order to know the effect of a particular processing. We used the following techniques : (1) Capillary wave probe : The effect of the film heterogeneity has been studied. In liquid/gas coexisting films, the liquid phase is practically invisible to the capillary wave. In solid/gas coexisting films, the continuity of the solid phase (islands) determins the propagation characteristics. (2) Reflection spectroscopy : The formation of polyion complex with a spread monolayer has been studied. The charge nutrality was found to be the deciding factor of the amount of the polymer on the monolayer and hence the adsorbed layer is monomolecular. The kinetics is completely governed by the diffusion of the polyymer in the solution and can be fitted to a universal curve. (3) Nonlinear optics : The 2nd and 3rd harmonic generations have been used to elucidate the nonlinear effects particular to the ultra thin films. Further refinement of the LB related techniques has been attempted as follows : (4) Single layer LB films have been used as an anisotropic substrate for the subsequent vacuum deposition. We demonstrated that the orientational order in the LB film can be transferred semi-quantitatively to the evaporated film. (5) An automated moving-wall trough with the capillary wave probe has been constructed and thick LB films have been succesfully fabricated in which the order in the L-film has been preserved in the LB-film.
这项研究的目的是主动控制影响 Langmuir fils 质量的因素,我们称之为“加工”。为了了解特定处理的效果,必须采用原位表征技术。我们使用了以下技术: (1) 毛细管波探针:研究了薄膜不均匀性的影响。在液/气共存膜中,毛细波实际上看不到液相。在固/气共存薄膜中,固相(岛)的连续性决定了传播特性。 (2) 反射光谱:研究了具有展开单层的聚离子络合物的形成。发现电荷中性是单层上聚合物量的决定因素,因此吸附层是单分子的。动力学完全由聚合物在溶液中的扩散控制,并且可以拟合通用曲线。 (3) 非线性光学:第二和第三谐波产生已用于阐明超薄膜特有的非线性效应。 LB相关技术的进一步改进已尝试如下:(4)单层LB膜已被用作后续真空沉积的各向异性基底。我们证明了 LB 薄膜中的取向顺序可以半定量地转移到蒸发薄膜中。 (5)构建了带有毛细波探针的自动移动壁槽,并成功制备了厚LB膜,其中LB膜中保留了L膜中的有序性。
