dc.description.abstract | The cathodic delamination of poly(styrene) [PS] model coatings from oxidecovered
zinc has been evaluated by scanning Kelvin probe (SKP). Linear and
acrylate cross-linked PS model coatings covalently bound to zinc oxide via
Zn─O─Si bonds have been prepared. PS was prepared by thermally initiated free
radical polymerization in the presence of vinyltrimethoxy silane modified zinc.
Cross-linkers ethylene glycol diacrylate (EDA) and hexanediol diacrylate (HDA)
were used in some preparations. Resulting polymers are 8–15 nm thick. PS model
coatings show a delamination rate of only ≈20% of that of comparable
poly(methyl methacrylate) [PMMA] samples. The slower cathodic delamination
of PS is attributed to denser chain packing and higher amounts of hydrophobic
moieties, leading to a reduction in penetration of corrosive species. As opposed to
the situation in PMMA, the addition of HDA increases the delamination rate, due
to its flexible chains and hydrophilic groups. The lowest delamination rate is
observed in the presence of 25% EDA. Consequently, ester hydrolysis of acrylates
accelerates delamination, it is however not the main factor in cathodic
delamination of such thin model system. | nb_NO |
