Polymer based nano composites play a crucial role in various applications. The unique properties are not only of interest for the classical field of rubber technology. Meanwhile there are several new applications in the area of micro electronics e.g. such as organic batteries. Due to the blending of nano particles and polymers, composites are created which exhibit improved features, e.g. silica-rubber blends show improved tensile properties and silicate plastics are fire retardant. In order to develop new materials with desired features a precise knowledge of the morphology and dynamics at the microscopic length scale is essential. Although a lot of studies exist, up to now the relationship between the properties of nano particles and the macroscopic behavior of the blends, which makes these systems so indispensable for industrial applications, has not been understood.
We present recent results on the structure and dynamics of silica-polymer composites obtained by neutron scattering experiments and compare them with the results of dynamical mechanical measurements.
