Abstract

Establishing the generality of any new preparative method is important for its future usefulness in applications of interest. In this paper, we build on results reported earlier for the formation of nanostructured ultrathin films from macromolecular precursors (a particular cationic polyelectrolyte and inorganic sheet silicate) by demonstrating that the method can readily be adapted to different polymers and more complex adsorption schemes. In particular, we used ellipsometry to monitor the regular growth of films incorporating poly(D-lysine hydrobromide) or poly(N-methyl-4-vinylpyridinium bromide) (PMVP) and hectorite. For the PMVP/ hectorite films, X-ray diffraction confirmed the presence of structural order by revealing a lattice spacing of 1.5 nm.

20. Substrates for these adsorptions were pre-treated by performing two adsorption cycles using a 5% (w/w) solution of PDDA and a 0.2% w/w hectorite suspension under conditions described previously (see reference 15). The substrates were primed in this way to provide a hectoritecoated substrate so that we could focus on multilayer formation independently from the issue of the affinity of the particular polymer for the native oxide on the silicon wafer.Google Scholar
