The interactions between nanoparticles and polymerchains lead to a change in dynamics such as mechanical properties, dielectric relaxation and polymer dynamics.
Also the modification of the parameters within the sample preparation process (amount of solvent, time frame between adding nanoparticles and drying the sample) could modify the actual distribution of the particles as well as these dynamic quantities.
This poster shows the results of SAXS, broadband dielectric and linear rheology measurements concerning a PBO-Silica-System under the variation of particle concentration as well as sample preparation parameters named above.
