Polyelectrolyte and carbon nanotube multilayers made from ionic liquid solutions.
The inevitable contact of substrates with water during the traditional practice of layer-by-layer assembly (LBL) creates problems for multiple potential applications of LBL films in electronics. To resolve this issue, we demonstrate here the possibility of a LBL process using ionic liquids (ILs), which potentially eliminates corrosion and hydration processes related to aqueous media and opens a...
متن کاملMechanical properties of nanotubes of polyelectrolyte multilayers.
The elastic properties of nanotubes fabricated by layer-by-layer (LbL) assembly of polyelectrolytes in the nanopores of polycarbonate track-etched membranes have been investigated by resonant contact Atomic Force Microscopy (AFM), for nanotube diameters in the range of 100 to 200 nm. The elastic modulus of the nanotubes was computed from the resonance frequencies of a cantilever resting on free...
متن کاملSurface thermodynamic properties of polyelectrolyte multilayers.
Multilayer architectures of polyelectrolytes fabricated by the layer-by-layer technique (LbL) on pretreated polymeric and inorganic substrates were studied by contact angle measurements. Poly(diallyldimethylammonium chloride), PDADMAC, and poly(sodium 4-styrenesulfonate), PSS, were used as polyelectrolytes. Contact angle data were used to calculate the van der Waals and Lewis acid-base componen...
متن کاملFormation of polyelectrolyte multilayers: ionic strengths and growth regimes.
This article presents a study of layer-by-layer (LbL) formation of poly-electrolyte multilayers (PEMs). Upon increasing ionic strength LbL growth patterns vary from linear for the lowest salt concentrations ([NaCl] = 0, 0.001, and 0.01 M) to exponential (for [NaCl] = 0.5 and 1 M). The slope of the linear growth at the lowest ionic strengths increases with increasing [NaCl]. During the LbL proce...
