      abstract     = {The combination of various types of materials is often used
                      to create superior composites that outperform the pure phase
                      components. For any rational design, the thermal
                      conductivity of the composite as a function of the volume
                      fraction of the filler component needs to be known. When
                      approaching the nanoscale, the homogeneous mixture of
                      various components poses an additional challenge. Here, we
                      investigate binary nanocomposite materials based on polymer
                      latex beads and hollow silica nanoparticles. These form
                      randomly mixed colloidal glasses on a sub-μm scale. We
                      focus on the heat transport properties through such binary
                      assembly structures. The thermal conductivity can be well
                      described by the effective medium theory. However, film
                      formation of the soft polymer component leads to phase
                      segregation and a mismatch between existing mixing models.
                      We confirm our experimental data by finite element modeling.
                      This additionally allowed us to assess the onset of thermal
                      transport percolation in such random particulate structures.
                      Our study contributes to a better understanding of thermal
                      transport through heterostructured particulate assemblies.},
