■ Abstract :
Soft materials including nanoparticles and polymers show properties that are highly dependent on how they are organized in space. Therefore, the ability to control their assembly structure is important in understanding their collective properties and realizing their full potential in various applications. Our group uses tools and concepts in nature to control the packing structure of nanoparticles and functional polymers. In particular, we use self-assembly of nanoparticles and amphiphilic block copolymers to prepare new hybrid materials with interesting collective properties. We also incorporate functional polymers such as conjugated polymers and DNA into amphiphilic block copolymer architecture, whose properties can be manipulated through self-assembly. These results demonstrate that amphiphilic self-assembly is a powerful tool not only for making complex nanoscale architectures but also for manipulating materials properties. Furthermore, this talk will present how we fabricate dynamic nanostructures based on the self-assembly principles.
