F. Schue et al., PLASMA DEPOSITION OF THIN FLUOROCARBON FILMS FOR INCREASED MEMBRANE HEMOCOMPATIBILITY, Journal of macromolecular science. Pure and applied chemistry, A31, 1994, pp. 1161-1168
The deposition of films from an argon plasma containing a mixture of e
thylene oxide or hydrogen and perfluorohexane was tried to obtain very
hydrophobic, less hydrophobic and intermediate coatings. This paper s
tudies more extensively the deposition of a thin coating from a perflu
orohexane and hydrogen plasma on polysulfone and polyhydroxybutyrate m
embranes to optimize their surface properties without affecting their
filtering properties. The plasma deposition of smooth and very hydroph
obic fluorocarbon coatings seems to increase the bio- and hemocompatib
ility of poorly biocompatible membranes. The treated substrates were c
haracterized by measuring the mass variations, surface profilometry an
d contact angle measurements, as well as scanning electron microscopy
and electron spectroscopy for chemical analysis.
