Spherical Nanoparticle Ordering in Block Copolymers
The ability to create ordered structures on the nanoscale is one of a number of critical issues in the ever-increasing quest towards miniaturization. Theories presented by Balazs and co-workers suggest that spherical nanoparticles included into a block copolymer would undergo self-assembly with size-selective separation and ordering. (1,2) Our work investigates the fundamental aspects of these theories, specifically those centered around size selectivity. By utilizing the natural self-assembling tendencies of block copolymers to form a well-known set of basic morphologies, we are able to create a structured matrix to house the particles. These composites are studied and characterized by numerous means including numerous X-ray and TEM/STEM techniques and methods.
