CAREER: Design and Discovery of Polymers with Pendant Rings for Membrane Gas Separations

Haiqing Lin Membrane Research Lab

The goal of this project is to elucidate the effect of pendant rings and crosslinking on membrane gas separation properties, and design advanced materials with superior gas permeability and selectivity, and great stability against aging and plasticization for practical separations.  

Overview

We will design and prepare hydrocarbon- or fluoro-polymers and investigate their structure/property relationship for membrane gas separation. This project is funded by the National Science Foundation.
