Research Statement

Our research covers a wide range of materials, including polymeric materials, ceramics and glasses, and composites. One of our main goals is to design materials with unique structure (down to nano- and molecular-scale) for specific applications, such as packaging, energy, catalysis, etc. In most cases, the structural design and control are the keys to the high performance of these materials.
Overall, we are engaged in four areas of materials research:

Multi-functional Nanostructured Materials
  • Synthesis of nanomaterials (nano-particles, tubes, platelets, porous materials, etc.)
  • Polymer nanocomposites
  • Bio-nanocomposites
  • Layer-by-Layer self-assembly
  • Thin films and fibers
 Solid State Chemistry
  • Layered compounds and intercalation/exfoliation chemistry
  • Porous materials and pillared layered compounds
  • Functional ceramics and glasses
 Polymeric Materials and Polymer Processing
  • Fluoropolymers
  • Polyolefins and thermoplastic polyolefins (TPOs)
  • Bio-polymers
  • Polymer composites/nanocomposites and blends
  • Polymer processing (injection molding, extrusion, blow molding, thermoforming, biaxial stretching, new processing technique development, etc.)
Green Science
  • Synthesize/isolate/derive valuable materials from biomass
  • Polylactic acid and other bio-based polymeric materials
  • Ionic liquids and their applications
