Complexes of sodium poly(4-styrenesulfonate) (NaPSS) and poly(diallyldimethylammonium chloride) (PDADMAC) were formed on mixing equimolar solutions in high salt concentration. Under ultracentrifugal fields, the complex precipitates were transformed into compact polyelectrolyte complexes (CoPECs), which showed extensive porosity. The mechanical properties of CoPECS make them attractive for bioim...

We show that ionically self-assembled polyelectrolyte/surfactant complexes allow a facile route to tailor the electrical surface resistance of paper sheets for antistatic dissipative regime. We use anionic polyelectrolyte carboxymethyl cellulose (CMC) where cationic alkyltrimethylammonium chloride surfactants (C(n)TAC) with the alkyl chain lengths n=12, 14 or 16 methyl units are ionically compl...

Cryo-TEM was carried out on samples containing polyelectrolyte-micelle complexes, formed by combining poly(diallyldimethylammonium chloride) (PDADMAC), a strong cationic polyelectrolye, with oppositely charged mixed micelles of sodium dodecyl sulfate (SDS) and nonionic Triton X-100 (TX100), in 0.40 M NaCl. Complexation appears to involve the formation of micelle-rich regions, presumably within ...

Fibers were electrospun from a solution comprised of oppositely charged polyelectrolytes, in efforts to achieve highly confined macromolecular packaging. A stoichiometric ratio of poly(allylamine hydrochloride) and poly(acrylic acid) solution was mixed in an ethanol-water co-solvent. Differential scanning calorimetry (DSC) analysis of electrospun fibers demonstrated no indication of glass trans...

Among different polymers, chitosan, the N-deacetylated product of the polysaccharide chitin, is gaining increasing importance in medical and pharmaceutical applications due to its good mucoadhesion and absorption enhancing ability. Moreover, chitosan shows the ability to form hydrogels able to control the rate of drug release from the delivery system as well as protect the drug from chemical an...

The current challenges in the food packaging field are, on one side, replacing plastic from non-renewable sources with biopolymers and, other hand, generating a material attractive properties for consumer. Currently, consumer is ecologically concerned; industry must think ahead to satisfy their needs. In this context, utilization of polyelectrolyte complexes (PECs) presents itself as an excelle...

Abstract There are so many significant developments made in drug delivery system (DDS) which Polymer DDS has reached great developments. The main motive of this paper is to focus on developing by Polyelectrolytes. Polymers have achieved much importance DDS. Polyelectrolytes shows an exceptional category polymer compounds containing opposite charged polyions mainly cationic or anionic charges; t...
