Research Overview

Current Research

My first research project is centered on experimental studies of factors that affect the anchoring behaviors of discotic liquid crystal (DLC). I eventually aim at templating the anchoring behavior of DLC under the effect of different factors. My second research project is focus on fabricating the molecularly imprinted mesophase, which finally can be developed as highly selective membrane.

Project 1: Fabrication of highly selective membranes for real-world applications by self-assembled thermotropic liquid-crystalline hexagonal mesophases with pore size of ~1nm.

Project 2: Development of highly selective nanosheets by self-assembled lyotropic liquid-crystalline lamellar mesophases with a thickness of ~3nm.
