Membranes separations are playing increasingly important roles in providing clean water to people and industry, environment protection and remedy, and energy conversion and storage, etc. The separation performances are dictated by the size, size distribution, geometry, and chemistry of membrane pores.

Our research is focused on the design, fabrication, upscaling, and applications of homoporous membranes (HOMEs). HOMEs are defined as membranes with monodispersed and through pores (the pores do not necessarily need to be cylindrical in shape), which are expected to exhibit selectivity, permeability, and fouling resistance.


Conventional membranes: 

Tortuous pores

Wide pore size distribution



Homoporous membranes:

Through pores

Monodispersed pores

Block copolymers (BCPs) and atomic layer deposition (ALD) are our main tools to build HOMEs.
