Layer-by-layer assembly of PAA and PLL on PEI-C primed SiOx. A) XPS spectrum after single-step PEI-C adsorption on SiOx B) XPS spectrum of (PEI-C/PAA)1-(PLL/PAA)10 adsorption on SiOx. C. Ellipsometry thickness of (PEI-catechol/PAA)1-(PLL/PAA)n. AFM image of a bare SiOx substrate (D), after (PEI-C/PAA)1 deposition (E), and after (PEI-C/PAA)1-(PLL/PAA)10 deposition (F). AFM images showed relatively smooth topography of the polymeric deposition.
