Research Topic

Membrane Separation Technology

Membrane processes, an energy-efficient separation technology, are our major research area. We currently concentrate on fabrication of membranes for pervaporation and membrane distillation. The next step is to prepare low-fouling membranes for protein separation and water treatment by combining pore control and material modification techniques.

Molecular Simulation

Another research subject is using molecular simulation to study how molecules permeate through polymeric membranes and to investigate the interaction between polymer and solvent. At the present stage, we concentrate on studying the permeation of drug molecules. The next step is to look into the relationship between the polymer-solvent interaction and the microstructure of the solution they form.

Tissue Engineering

Tissue engineering is a major biomedical research stream in the 21st century. Our present research interest lies on preparation of scaffolds for tissue engineering. The material studied includes biodegradable PLGA, PLLA and chitosan. We are cooperating with the medical school to develop the GTR membranes and cell-specific bone regeneration scaffolds, for treating periodontal disease.
