“…A wealth of heterostructures exist which contain PB in combination with other materials, such as dye-sensitised titania 3 and conductive polymers. 4,5 There have also been a number of studies that employ multiple Prussian blue analogues (PBAs) to create heterostructures in the form of thin films or nanoparticles to study photoinduced magnetism 6,7 and magneto-structural effects. [8][9][10] Their electrochemical 11 and optical 12 properties have also been studied.…”

The distinct optical absorption spectra of the two layers allowed spectroelectrochemical measurements to probe the electrochemical activity of the individual layers during the switching of the Prussian blue layer.We found that for producing layers of equal optical density, the thickness of the layers had to be different due to a difference in oscillator strength for the metal-to-metal charge-transfer transition. The films used here had a thickness of 300 AE 70 nm and 30 AE 15 nm for the FeCr and FeFe sub-layers, respectively.The colouration efficiency was found to be 147.8 AE 0.8 cm 2 C À1 for the multilayered film. These resultsshow that it is possible to obtain bilayers of Prussian blues that, with a unique optical spectral fingerprint of each sub-layer, retain the electrochromic functionality and therefore enable layer-sensitive studies of charge-transfer processes in thin film heterostructures of multifunctional materials.

“…Since then, the LbL technique has attracted significant interest as a simple, highly versatile approach and has been widely used to prepare nanostructured materials with tailored properties on macroscopic surfaces [38] as well as on micro-and nanoparticles [39][40][41][42][43]. Classically, the LbL deposition procedure involves the stepwise, electrostatic assembly of the oppositely charged polyelectrolytes, usually by consecutive dipping a substrate into the polyelectrolyte-containing solutions with the intermediate rinsing step that enables forming a multilayer coating with a nanometer scale precision.…”

“…5,6 Thus, its simplicity, universality and the high quality of obtained films make the LbL an attractive method for the production of stratified thin films, in which layers are organized in a specifically predetermined order. 7 It leads to a broad range of applications including (bio)sensing, 8 (bio)electronics, targeted delivery of active agents ,9 protein adsorption, 5,10 antimicrobial coatings, 11 tissue engineering, 12 implants, adhesives, catalysis, 13 separation, storage and conversion of energy. 14 The polyelectrolyte film architecture and properties such as thickness, roughness, wettability, solvent responsiveness, surface charge and permeability are controlled by many parameters, which enable the design of appropriate, desired structures.…”

Interfacial and structural characteristics of polyelectrolyte multilayers used as cushions for supported lipid bilayers

et al. 2017

The surface properties of polyelectrolyte multilayers (PEMs) obtained via sequential adsorption of oppositely charged polyions from their solutions and used as cushions for supported lipid bilayers were investigated. Five types of polyelectrolytes were used: cationic polyethyleneimine (PEI), poly(diallyldimethylammonium)chloride (PDADMAC), and poly-l-lysine hydrobromide (PLL); and anionic polysodium 4-styrenesulfonate (PSS) and poly-l-glutamic acid sodium (PGA). The wettability and surface free energy of the PEMs were determined by contact angle measurements using sessile drop analysis. Electrokinetic characterisation of the studied films was performed by streaming potential measurements of selected multilayers and the structure of the polyelectrolyte multilayer was characterized by synchrotron X-ray reflectometry. The examined physicochemical properties of the PEMs were correlated with the kinetics of the formation of supported lipid bilayers atop the PEM cushion.
