Microrheology in systems of polymeric colloids
Original language description
Passive microrheology is a novel approach determining viscoelastic properties of the soft materials based on the thermal movements of inserted particles. This method was utilized to investigate properties of selected polymeric colloids and measured values were compared with classical rheology results. Two different diameters of probes were applied to characterize measurability range of the passive microrheology for various polymeric materials. In our work, poly(sodium 4-styrenesulfonate) (PSS) and sodium carboxymethyl celullose (CMC) were used. Our results show comparable values for samples of lower concentrations determined by classical rheology and passive microrheology, using various particle sizes for PSS and CMC. In case of higher concentrations of polymers, discrepancies in measured values from different techniques were observed. These differences can indicate applicability limits of the method but can also demonstrate characteristic properties of the sample microstructure. Evalu
