Research Interests  

When polymers are confined under nanoscale, their packing of molecular chains is perturbed, resulting in different structure and unique physical, mechanical, thermal, electrical, and optical properties. My research interests focus on the surface mechanics and interface mechanics of polymer nanostructures, thermophysical properties and thermal transport of polymer and its nanocomposites at the nanoscale, and the potential applications in energy field. 
  • Thermophysical properties of polymeric materials at the nanoscale
  • The thermophysical properties of polymer thin films were investigated by a nano-thermomechanometry, a customer-designed scanning probe microscope technique. Finite element method simulations were performed to explain the effects of the thermal and mechanical coupling on these measurements.
  • Mechanics of nanopatterned polymer structures
    • The temperature and molecular weight dependence of the slumping and stability of nanoscale polymeric patterns, which were induced by nanoimprint lithography process, were investigated.
    • The elastic moduli of one-dimensional (1D) polymer nanoliners are measured by surface wrinkling experiments. The dimensional dependence of the mechanical properties is carefully analyzed and related to the perturbation on the packing of molecule chains under 1D nanoconfinement. 
  • Thermal transport properties of polymeric materials and its nanocomposites
  • The thermal conductivity of polymeric materials is measured by 3ω thermal measurements. Fullerene, clay, and graphene oxide are added into polymers to make nanocomposites to improve the thermal transport properties.
  • Thermal stability and proton conductivity of Nafion and its nanocomposites
