عنوان انگلیسی Ion Pair [NaCMC-CAPB] Complex Formed via Interaction of Carboxymethylcellulose Sodium Salt (NaCMC) with Cocamidopropyl Betaine (CAPB)
چکیده انگلیسی مقاله Polyelectrolyte complexes (PECs) based on oppositely charged polyelectrolytes-surfactants have gained great attention for their potential range of applications, such as membranes for filtration or in fuel cells and flocculants for water purification. In this current paper, the complex formed between carboxymethylcellulose sodium salt polyelectrolyte and cocamidopropyl betaine surfactant was reported. Conductimetry, potentiometry, viscometry and FTIR methods were used to study the structure and properties of this complex. The result shows that the complex is formed by ionic binding and hydrophobic aggregates. The measurements confirmed the interactions between the different functions in both components. Also, the characteristic concentrations of the complex NaCMC-CAPB such as critical aggregation concentration (CAC) and saturation concentration (X2) were calculated using the conductivity plots. The presence of charges in the complex explains water solubility in a wide range of polyelectrolyte and surfactant concentrations. Additionally, the effect of surfactant on reduced viscosity of polyelectrolyte solutions will be discussed.
