Research Abstract

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.
