摘要

The chemical inertness,thermal stability,and low dielectric constant characteristics of polytetrafluoroethylene make this polymer very attractive for advancded technology applications.Current production technologies are not adequate for the deposition of often desired,thin-layer Teflon coatings.In this article the synthesis and characterizatio of Teflon-like macromolecular structures from dodecafluorocyclohexane and octadecafluorodecaline vapors under RF-cold-plasma conditions is discussed.It was demonstrated,based on high-resolution ESCA,ATR-FTIR,and LD-FT-ICR-MS investigations,that the deposited Teflon-like layers are built of CF,CF_2,CF_3,and exsitu origing C-O groups with an over 60% fluorine content,and that they have a branched and/or crosslinked nature.These structures have a relatively high thermal stability (340 deg C) and are characterized by a low dielectric constant (2.1).Plasmaenhanced coatings of Teflon-like layers can be performed at room temperatures at large substrate areas.
