Electroless formation of conductive polymer–metal nanostructured composites at boundary of two immiscible solvents. Morphology and properties

The effect of the functionalization and molecular weight of cationic dextran polyelectrolytes on their electrochemical behavior at the water/1,2-dichloroethane interface

“…20 Particularly, regarding the study of polyelectrolytes, polymers and surfactants at liquid/liquid interfaces, this methodology has been successfully employed to elucidate the interaction of the cationic polyelectrolyte polyquaternium-10 with anionic surfactants of different chain length and head group; 36 to characterize the behavior and interaction with phospholipid monolayers of chitosan, 39 dextran sulphate 40 and nanostructures composed of dextran sulfate/ruthenium nanoparticles; 41 to sense the anticoagulant heparin (a multi-charged polysaccharide) and its antidote protamine (a charged polypeptide) in aqueous/PVC plasticized membranes via amperometric [28][29][30][31][32][33][34] and potentiometric methods; [42][43][44][45] to study the counterion binding to the protamine polyion in aqueous solution; 15 to study the behavior of proteins, DNA and their complexes; 46,47 and to characterize the interaction between humic acids and herbicides, 48 the association of pharmaceutical drugs with neutral or charged sites in hydrogels and membranes, 49,50 the transfer process of dendritic molecules 51 and the formation of a conductive polymer using nanostructured composites. 52 In the present study, cyclic voltammetry is used to characterize the electrochemical behavior of CD, DEAE-D and AD at the polarized aqueous/1,2-dichloroethane interface, with the aim of correlating the nature of substituents in the chain with the interfacial behavior of the resulting polyelectrolyte. An investigation into the influence of the scan rate, concentration, pH, the nature and the concentration of the anion present in the electrolyte of the organic phase and into the effect of the polymer molecular weight is presented.…”

Polypyrrole–gold nanostructured composite, active and durable electrocatalytic material

“…The principles of this easy and effective technique were described in reference [14]. The used procedure of formation of noble metal-conducting polymer composite is based on the electroless redox liquid-liquid interphase synthesis [15,16].…”
