3D solid supported inter-polyelectrolyte complexes obtained by the alternate deposition of poly(diallyldimethylammonium chloride) and poly(sodium 4-styrenesulfonate) Guzmán Solís, Eduardo Maestro, Armando Llamas, Sara Álvarez-Rodríguez, Jesús Ortega Gómez, Francisco Maroto-Valiente, Ángel González Rubio, Ramón This work addresses the formation and the internal morphology of polyelectrolyte layers obtained by the layer-by-layer method. A multimodal characterization showed the absence of stratification of the films formed by the alternate deposition of poly(diallyldimethylammonium chloride) and poly(sodium 4-styrenesulfonate). Indeed the final organization might be regarded as threedimensional solid-supported inter-polyelectrolyte films. The growth mechanism of the multilayers, followed using a quartz crystal microbalance, evidences two different growth trends, which show a dependency on the ionic strength due to its influence onto the polymer conformation. The hydration state does not modify the multilayer growth, but it contributes to the total adsorbed mass of the film. The water associated with the polyelectrolyte films leads to their swelling and plastification. The use of X-ray photoelectron spectroscopy has allowed for deeper insights on the internal structure and composition of the polyelectrolyte multilayers. 2023-06-18T06:50:03Z 2023-06-18T06:50:03Z 2023-06-18T06:50:03Z 2016-02-05 journal article https://hdl.handle.net/20.500.14352/24348 2190-4286 10.3762/bjnano.7.18 eng FIS 2012-28231-C02-01 FIS 2014-62005-EXP FASES and PASTA Marie Curie ITN-CoWet CM1101 and MP1106 https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España Beilstein-Institut zur Förderung der Chemischen Wissenschaften
