Controlled structure and functionalization in block copolymer thin films

초록

The self-assembly of block copolymers provides a versatile platform for the fabrication of nanostructured materials. Scaffolds and templates produced from oriented morphologies of block copolymers have been used in applications ranging from filters with well-defined pore sizes for the separation of viruses to floating gates in flash memory storage devices. Yet, to utilize fully the areal density of elements afforded by block copolymers and to realize the potential of generating addressable media, control over the orientation and long-range lateral ordering of the copolymer microdomains is necessary. In this talk, several strategies to control the structure and functionalize the thin film including the diblock copolymer blend and triblock copolymer will be given, where the structure was examined in detail by AFM, TEM, GISAXS, and neutron reflectivity.
