Title: Ion distribution in dry polyelectrolyte multilayers: a neutron reflectometry study

Abstract

Counterions were found to be uniformly distributed in polycation-terminated films of poly(diallyldimethylammonium) and poly(styrenesulfonate) prepared on silicon wafers using layer-by-layer adsorption.

Figures / Tables:

Scheme 1 Scheme 1: A) Stoichiometric polyelectrolyte complex films contain only polymer/polymer interactions – intrinsic sites, while B) overcharged or overcompensated films, in addition to these sites, also contain extrinsic sites, polymer/counterion interactions, stemming from the excess of one polyelectrolyte. For simplicity, the scheme shows idealized layering in a cross-section.
