The scale-up of material microstructuring: from scanning probes to self-assembly
- 114 Downloads
The behaviour of materials is governed by their microstructures, whether they are naturally occurring or artificially designed. Engineered microstructures lead to materials with new and useful functions, but their real-world application requires scalable microstructuring methods for production. This review discusses several principles of fabrication and their scalability. Replication by imprint and multiplexed probes are obvious candidates for scale-up, but they limit the choice of materials. The assembly of interacting particles is a promising, scalable fabrication method. A wide range of materials can be obtained as particles which assemble into regular superstructures, but large-scale structuring at high precision and yield as yet remains a challenge.
