Description
  • Je popsána příprava řetězců (brush) polyakrylové kyseliny (PAA), naroubovaných na povrchu pevného sustrátu s gradientem hustoty roubování a rovněž analyza jejich chování. Nejprve byl povrch sustrátu pokryt polymerizačním iniciátorem s gradientem obsazení povrchu a z něho pak byly cestou „grafting from“ připraveny řetězce Pt-BuA, které byly nakonec převedeny na PAA. Tlouštka vrsvy PAA na povrchu byla měřena spektroskopickou elipsometrií ve vodném prostředí s různým pH a různou iontovou sílou. (cs)
  • Experiments are described giving rise to the polyacrylic acid (PAA) brushes with a gradient of grafting densities on solid surfaces and provide analysis of their properties. The PAA brush gradients are generated by first covering the substrate wit a gradient of polymerization initiator, followed by the grafting from polymerization of tert-butyl acrylate (t-BuA) and finally converting the Pt-BuA into PAA. Using spectroscopic ellipsometry, the wett thickness of the grafted PAA chains were measured in aqueous solutions at different pH values and different ionic strengths.
