Molecular-Level Processing of Conjugated Polymers. 4. Layer-by-Layer Manipulation of Polyaniline via Hydrogen-Bonding Interactions

Abstract: The molecular-level layer-by-layer processing of polyaniline with a variety of different nonionic water soluble polymers has been demonstrated. This new type of layer-by-layer adsorption process is driven by hydrogen-bonding interactions and has been accomplished with poly(vinylpyrrolidone), poly(vinyl alcohol), poly(acrylamide), and poly(ethylene oxide). FTIR spectroscopy measurements confirm a high level of hydrogen bonding between polyaniline and the nonionic polymer in the multilayer films. The effects of … Show more

“…Not only electrostatic interactions but also other interactions between polymers have been utilized for the LbL assembly of functional polymers. [2] The LbL assembly method potentially could be used in applications involving time-controlled desorption of polymer constituents. Several reports have already demonstrated deconstruction (or simple desorption) of LbL assemblies that depend on the preparation conditions and/or the immersion media.…”

“…Trabalhos recentes [28][29][30] mostraram que outros tipos de interação, diferentes da atração eletrostática, podem predominar no processo de automontagem. Polímeros condutores como a polianilina e seus derivados encontram-se no estado carregado (dopados) quando em soluções de baixo pH 31 .…”

“…Polímeros condutores como a polianilina e seus derivados encontram-se no estado carregado (dopados) quando em soluções de baixo pH 31 . Verificou-se, entretanto, que estes polímeros podem ser automontados a partir de soluções em pHs elevados, ou seja, como se fossem polímeros neutros 28,29 . Neste caso, o processo de automontagem é governado por interações não iônicas, como ligações de hidrogênio.…”
