| X. Han is working on supercritical CO2 assisted polymer processing,
including foaming and blending extrusion. Now research mainly focuses on
nanocomposite foams with excellent thermal insulation, barrier property,
and mechanical strength. The phase equilibrium behavior of the polymer/CO2
system and the corresponding rheological properties are also studied. |

| My research is in the field of polymer processing, as a part of the NSF sponsored
Center for Advanced Polymer and Composite Engineering (CAPCE) at The Ohio State University. My dissertation
investigates extrusion of polymeric foams, for both closed and open cell products. In particular, this work studies polystyrene
nanocomposite foams using carbon dioxide as a physical blowing agent and organophilic montmorillonite nanoclay as a nucleation agent.
The two major components of my work are viscosity and cell growth. The first part is to examine the effects of pressure, blowing agent concentration,
and nucleation agent concentration on shear viscosity. The latter stage uses modeling and die design to control cell size and openness |

My research focus on experiment and molecular simulation. With a microbalance system, we measured adosrption/desorption isotherms
of CO2 on zeolite from vaccum to 2800 PSI at 32,35,40 and 50 C.Our setup measures isotherms near continuously.
We are also doing molecular simulation of adsorption of supercritical CO2 on NaY Zeolite. |
