The nanometer scale structure of colloid-filled polymeric materials depends on complex interactions and correlations between the components.
By measuring the motion of micrometer-size particles, we determined the transition between dilute and entangled regimes for a semiflexible polymer solution and identified the formation of polymer-depleted layers near the particle surfaces. Our results are in good agreement with recent theoretical models.
