Self-assembled nanostructures from block copolymers have been studied for years at Almaden Research Center. Current research focuses on advancement in new materials, controlled assembly of nanostructures, and device oriented placement on substrates. While effort to synthesize new block copolymers with novel molecular architectures continues, hybrid approaches using simple mixtures are being introduced. As shown below, well-defined nanostructures ranging from spheres to cylinders to lamellae can be obtained from simple binary mixtures of an amphiphilic diblock copolymer and a silicon-containing inorganic precursor. Thermal crosslinking followed by thermolysis of the organic block copolymer gives nanostructured inorganics with well-defined morphologies which can be observed using Atomic Force Microscopy.
