Weatherability and wear resistance characteristics of plasma fluoropolymer coatings deposited on an elastomer substrate

X-Ray Photoelectron Spectroscopy for Characterization of Engineered Elastomer Surfaces

“…From systematic studies of fluorinating process under different conditions we concluded that high concentration of fluorine on the elastomer surface, typically higher than 7%, is associated with formation of fluorine-containing functional groups in form of CF, CF2 or CF3.The presence of CF and CF2 can be explained by H substitution and chain scissions [32], where -CF2-represents the main chain of the polymer, -CF-component could indicate crosslink sites [72], and-CF3 component indicates end groups of polymer chains [72] and grafting [32]. These findings imply enhancing of cross-linking in the elastomer due to plasma processing with fluorine-containing gas.…”

Role of the surface chemistry of plasma polymer layers on their long‐term antifogging behavior

“…Surface rearrangement of the polymeric chains is frequently investigated by air/ WCAs measurement [19,20] whereas postoxidation due to free radicals in the plasma coatings, by X-ray photoelectron spectroscopy (XPS). [21][22][23] Thus, in this study, thermal stability and wet surrounding resistance of hydrophilic/oleophobic plasma films deposited on polycarbonate (PC) substrates are carried out by wettability measurements and XPS analysis. The antifogging properties of aged surfaces are also examined by the water vapor contact test.…”

Fluorinated modification of hyperbranched polyesters used for improving the surface property of UV curing coatings

“…Therefore, the fluorinated materials are considered to be used for high performance coatings on different substrates, showing the good protection against corrosion, weathering, and environmental pollution [11][12][13][14].…”
