Gas Jet Deposition of Teflon-like Films and Ultra-Dispersed Particles

Polymer gas jet deposition is proposed as a method to produce Teflon-like films that allows control on morphology and structures on different length scales including nanometer. Gasified Teflon is used as precursor and a computational modeling is proposed for better understand the gas dynamic occurring at the impact of the hypersonic C2F4 jet with substrate. The properties of the films produced are presented and discussed on the basis of their morphology as well as of AES, XPS and UPS electron spectroscopies, which are demonstrated. Gas Jet deposition is shown to be a quite promising method to produce and control the synthesis of Teflon-like and possibly of other polymers films.
