摘要: Polytetrafluoroethylene (PTFE), polyhexafluoropropylene (PHFP) and polychlorotrifluoroethylene (PCTFE) were heated to their decomposition temperature in a high vacuum. The emitted fragments passed an electron cloud, condensed on substrate formed fluoropolymer film. Growth rate of PTFE PHFP films increased up factor five the presence cloud. Mass spectrometry revealed changes mass spectra generated by thermal only under activation. observed different for each fluoropolymer. Infrared spectroscopy (IRS) showed that structure was close bulk polymers. Atomic force microscopy (AFM) has morphologies PTFE, PCTFE films, suggesting Volmer–Weber growth mechanism but Frank-van der Merwe one PCTFE. All smooth at nanoscale transparent from ultraviolet near-infrared region. Additional radio frequency (RF) plasma ignited low pressure mechanical characteristics without losing optical transparency smoothness.
