Nanocomposites

 

Polymer nanocomposites are intensely investigated because nanoparticles improve polymer properties already at very low volume fractions and because they provide additional functionalities that would otherwise not be available for polymeric materials. Further developments are seriously delayed by the large tendency of nanoparticles to aggregate in the polymer matrix. This also prevents the elucidation of the nanoscale effects that lead to the observed efficiency of these materials. We have elaborated a route to fully miscible nanocomposites where the nanoparticles do not aggregate even at the highest volume fractions. This breakthrough allows the efficient preparation of nanocomposites and the control of the interparticle distance in a range of 5 – 50 nm relevant for applications in magnetic storage and hybrid solar cells.
