A series of well-defined brush, star, and block copolymer systems bearing various functional moieties (biomolecules, mesogens, and charge-trapping molecules, and so on) were newly synthesized. All the polymer were found to be thermally stable up to high temperatures (200-500℃), providing a process and utilization windows. They often self-assembled and formed various unique nanostructures, depending on the chemical architecture and regularity as well as the thermal-annealing, solvent-annealing or their combinations. Such self-assembly nanostructures and their orientation were successfully analyzed in detail using synchrotron grazing incidence X-ray scattering and reflectivity; the determined nanostructures were understood with considering favorable interactions of the polymer backbones and functional moieties. The phase and surface characteristics in the self-assembled nanostructures can be well controlled. In particular, biomolecule-containing brush polymer self-assemblies were successfully controlled to always provide biomolecule rich surface over various processes, which are essential to demonstrate excellent biocompabilities, anti-adherence of bacteria, anti-adsorption of proteins, and drug deliveries. Moreover, some other interesting nanostructure systems demonstrated ultra-low dielectric constant, programmable digital volatile and nonvolatile memories or liquid crystal controllability, which are highly demanded for advanced microelectronics and flat panel displays.
