Block Copolymer - Nanoparticle Composites in Electric Fields — •Clemens Liedel, Kerstin Schindler, Christian Wilhelm Pester, and Alexander Böker — Lehrstuhl für Makromolekulare Materialien und Oberflächen, DWI an der RWTH Aachen e.V., RWTH Aachen University, D-52056 Aachen, Germany

The creation of thin and densely-packed metallic wires is of key importance for creating new devices for electronic applications. Because of its size, block copolymers and metal nanoparticles are promising materials for this purpose. By creating composite materials from both, it is possible to combine the possibility of orienting block copolymer structures in electric fields with the conductivity of metal nanoparticles. Hence, ordered metallic structures are accessible.

We present a deeper understanding of nanoparticle - block copolymer composites in electric fields. Therefore, we show the influence of nanoparticles on the field strength that is necessary for aligning the morphologies. In addition, we describe the impact on the kinetics of orientation and the resulting order parameter.

Understanding composites from block copolymers and nanoparticles in electric fields may help to build new devices in the field of optical gratings, data storage or organic-inorganic solar cells.
