dc.description.abstractEnWe present a measurement of the viscoelastic properties of polymer solutions using the resonant thermal capillary fluctuations (RTCF) of the surface of a polymer solution droplet. The instantaneous deflection of a cantilever in contact with the drop surface allows for measuring the nanoscale thermal fluctuations of the interface. From the power spectral density of the measured fluctuations, we determine the two components of the rheological response of the fluid. Our experimental results were compared with rheological measurements using a classical commercial rheometer. We find a good agreement between the two measurements. Additionally, our experiments allow to extend the range for dynamical measurements of the rheological properties of the solutions up to 20000 s-1 .
