Research Overview

Design and synthesis of functional polymers. Construction of hybrid nanomaterials, hierarchical ceramic nanocoating, and chiral ceramics with functional polymers as templates.

Research Subjects

  • 1.Synthesis of specially structured polyoxazolines and polyethyleneimines.
  • 2.Self-assembly of polymers in aqueous media.
  • 3.Chiral polymeric supramolecules.
  • 4.Temporally and spatially controlled sol-gel reactions.
  • 5.Synthesis of chiral silica and metal oxides.
  • 6.Chiral discrimination and racemic resolution based on chiral ceramics.

Introduction:

Shape control, from molecularly structured scales and self-assembled supramolecules entities to hierarchical metal oxides, directed by shaped organics, is important because material functions often depend on morphology. We are particularly interested in the concept of shape control in designing hybrid nanomaterials for new functional materials.
