Polymer Thin Film & Analysis Laboratory

Du Yeol Ryu research group

Research Interests

  • Self-assembled nanostructures (including quasicrystals) by block copolymer
  • Interface engineering : Interaction between polymer film and adjacent surfaces
  • Hardcore polymer physics : glass transition, order-disorder transition, and dewetting
  • Organic-inorganic hybrid with 3-dimensional gyroid and its application to optics
  • Analysis with precision by small-angle scattering (X-ray or neutron)

Current Researches

Block copolymer (BCP)

  • Fundamental issues on BCP self-assembly in both bulk and thin film states.
  • Understanding the core properties leads to a firmer foundation for practical applications.
