Abstract

original image

On page 5946, Tobin J. Marks, Mark A. Ratner, Michael T. Lanagan, and co-workers report a series of metal oxide core/Al2O3 shell polypropylene nanocomposites synthesized via in situ polymerization utilizing a metallocene polymerization catalyst chemisorbed on the nanoparticle surfaces. The good particle dispersion and tunable shell thickness afford materials with high energy storage capacities and low dielectric loss at high voltages.
