项目摘要

Physical vapor deposition (PVD) and vapor deposition polymerization (VDP) are useful and promising methods for the preparation of organic and polymeric thin films with desired structures. Only a few studies, however, have been reported on the formation mechanisms of these thin films.Film formation mechanism during the alternating vapor deposition polymerization was studied by monitoring the change in the amount of adsorbate during the deposition. Azelaoyl dichloride (ADC) monomers can be chemisorbed onto the diaminoheptane (DAH) layr and form a mono-molecular layr with a normal molecular orientation. DAH monomers can be chemisorbed onto the ADC layr and form a multi-molecular layr on the surface of the chemisorbed DAH layr with the normal molecular orientation. Polyamide thin film with a layred structure like an Langmuir-Blodgett film was obtained by use of the alternating vapor deposition polymerization method, similar to the atomic layr epitaxy method.This research also aims to investigate the adsorption/desorption process in PVD and VDP.Observation using a quartz crystal microbalance (QCM) reveals that the first stage in thin film formation involves two types of adsorption which should be termed as physisorption and chemisorption. Analysis of the physisorption behavior of organic molecules gives the mean stay time and the adsorption energy of the molecules on the substrate.

物理蒸气沉积（PVD）和蒸气沉积聚合（VDP）是用于制备具有所需结构的有机和聚合物薄膜的有用方法。然而，仅报告了有关这些薄膜的形成机理的少数研究。通过监测沉积过程中的吸附物量的变化，研究了交替蒸气沉积聚合过程中的FILM形成机制。偶氮酰二氯化（ADC）单体可以化学吸附到二氨基己烷（DAH）Layr上，并形成具有正常分子方向的单分子layr。 DAH单体可以在ADC Layr上进行化学吸附，并在化学吸附的DAH Layr的表面形成多分子的Layr，并具有正常的分子取向。与langmuir-blodgett膜一样的聚酰胺薄膜是通过使用交替的蒸气沉积聚合方法获得的，类似于原子级别的外观外观方法。这项研究还旨在研究PVD和VDP.Obserative中的吸附/吸附过程使用石英晶体微平衡（QCM）表明，薄膜形成的第一阶段涉及两种类型的吸附，应将其称为物理吸附和化学吸附。分析有机分子的物理吸附行为可得出平均停留时间和分子在底物上的吸附能。
