Ionic microgels, in particular, are highly sensitive to changes in environmental conditions such as temperature, solvent quality, polymer cross-linking, suspension ionic strength and particle concentration, which allows for controlling their size and effective interaction. In this work, we theoretically study the effects of concentration-dependent deswelling of weakly-crosslinked ionic microgels on dynamic and structural suspension properties [1]. We use and compare two different theoretical approaches to calculate the equilibrium microgel size, namely the Denton-Tang method based on Poisson-Boltzmann cell model [2], and a multiparticle-based thermodynamic perturbation method [3]. In combination with an effective interaction potential for spherical ionic microgels [4], we compute static pair correlation functions and structure factors. These are used as input in our calculations of dynamic suspension properties including the hydrodynamic function, collective diffusion coefficient, and low- and high-frequency viscosities. As a consequence of the concentration-dependent deswelling, we show how the collective diffusion is enhanced while the viscosity is lowered in suspensions of ionic microgels.References[1]	M.
