WebPolyelectrolyte coacervates (PECOVs)52−55 represent an interesting intermediate between PECs and solutions of the same polyelectrolytes (i.e., where all polymer chains are isolated). These coacervates contain weakly bound polyelectrolytes that are so well hydrated that they behave like fluids. WebCurrent literature on polyelectrolyte multilayer deposition by spraying is reviewed to place the spraying method in its context, and the fundamental issues that have been addresses so far are reviewed. The alternate deposition of polyanions and polycations on a solid substrate leads to the formation of nanometer to micrometer films called Polyelectrolyte …
WebJun 18, 2024 · Upturns in the scattering at low angle, seen for complexes in lower [KBr], are consistent with porosity, observed macroscopically as whitening of the bulk complex—a universal property of polyelectrolyte complexes. Reasons for this porosity, imaged by scanning electron microscopy, are discussed. WebApr 5, 2024 · The sensor surface was modeled using the Au_nk1_mat layer (100 nm), while the spin-coated polystyrene as well as the adsorbed coatings were modeled by an individual Cauchy layer with parameters A n = fitted (PS = 1.54; adhered films = coupled Cauchy), B n = 0.01, C n = 0, and k = 0. The models were fitted using a specified spectral range of λ ...
