Dynamics of interface of gels undergoing volume phase transition
The dynamics of interface of chemical gels undergoing volume phase transition is studied for one-dimensional geometry Permeation of solvent through the interface is taken into account It is shown that the rate determining process of motion of interface is the permeation of solvent through the bulk domains Generalization to three-dimensional case is also discussed.
متن کاملVolume Phase Transition of Swollen Gels: Discontinuous or Continuous?
Poly(N-isopropylacrylamide) (PNIPAM) linear chains and spherical microgels were studied using laser light scattering. The volume change associated with the temperature dependence of the hydrodynamic radii of both the linear chains and the spherical microgels is continuous, in contrast to a discontinuous volume phase transition observed for a bulk PNIPAM gel with an identical composition. A reex...
متن کاملSalt-Induced Swelling and Volume Phase Transition of Polyelectrolyte Gels
A theoretical model of polyelectrolyte gels is presented to study continuous and discontinuous volume phase transitions induced by changing salt concentration in the external solution. Phase diagrams are constructed in terms of the polymer–solvent interaction parameters, external salt concentration, and concentration of fixed charges. Comparisons with previous experiments for an ionized acrylam...
متن کاملSwelling/deswelling of anionic copolymer gels.
Studies of dynamic and equilibrium swelling of ionic gels are important in understanding the diffusion of physiologically important fluids in materials for site-specific controlled drug delivery applications. The dynamic and equilibrium swelling properties of dry glassy poly(2-hydroxyethyl methacrylate-co-methacrylic acid) and poly(2-hydroxyethyl methacrylate-co-acrylic acid) polymeric networks...
متن کاملRheological properties of suspensions of thermo-responsive poly(N-isopropylacrylamide) microgels undergoing volume phase transition
The rheological properties of suspensions of thermo-responsive poly(N-isopropylacrylamide) (PNIPAM) microgels are investigated in the swollen and collapsed states using oscillatory and long-time creep measurements. In the swollen state with repulsive interparticle interaction, the zero shear viscosity and quasi-plateau modulus are solely governed by the effective volume fraction (φeff) and are ...
