Equilibrium Swelling Study of Cationic Acrylamide-Based Hydrogels: Effect of Synthesis Parameters, and Phase Transition in Polyelectrolyte Solutions
Cationic copolymer gels of acrylamide and [(methacrylamido) Propyl] trimethyl ammonium chloride (MAPTAC) were synthesized by free radical aqueous solution polymerization. The Taguchi method, a robust experimental design, was employed for the optimization of the synthesis based on the equilibrium swelling capacity of the hydrogels. Based on Taguchi method a standard L16 orthogonal array with fiv...
متن کاملEquilibrium swelling, conductivity and electroactive characteristics of polyacrylamide hydrogels
Polyelectrolyte hydrogels are currently being studied extensively towards the realization of soft actuators. The conductivity, swelling behaviour and electroactive characteristics of partially hydrolysed polyacrylamide hydrogels, crosslinked to various extents are investigated. Conductivity studies have been made by means of dielectric relaxation spectroscopy both for hydrogels and dry gel powd...

متن کاملSwelling characterization and drug delivery kinetics of polyacrylamide-co-itaconic acid/chitosan hydrogels
Hybrid polymeric networks composed of polyacrylamide and chitosan were developed to determine their swelling and ascorbic acid delivery kinetics at various chitosan concentrations. The hybrid acrylamide/chitosan hydrogels were synthesized in aqueous itaconic acid solution (1% w/w). Young’s modulus was also evaluated for the hydrogels, and the results were correlated with the swelling properties...
متن کاملThe Adsorption of Polyacrylamide Nanocomposite Hydrogels on Sandstone
A key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. So, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. The X-ray diffraction patterns indicated that exfoliated ty...
