Polymer composites are materials of great potential due to its improved final properties. The incorporation of fillers into ordered nanostructures of block copolymers can provide control over the distribution and orientation. Then nanocomposites with enhanced mechanical, optical, electrical and/or barrier?s properties can be obtained. The incorporation of fillers can be achieved by melt-mixing, a solvent-based processing or a combination of both. In this work, a solvent-based processing was used with the subsequent application of an alignment technique: roll-casting. Roll-cast technique allows obtaining macroscopically oriented films while a simple cast technique produces isotropic films.
