Polymer and Molecular Characterization


The polymer and molecular characterization facility is a collection of instruments by STAMI faculty members with the capability of measuring: 1) molecular weights of polymers by GPC at ambient and high temperatures; 2) sizes of macromolecular particles by DLS; 3) liquid-solid surface interface properties by contact angle measurement; 4) the absorptive properties of solutions, solids, and thin films from UV to the near IR wavelengths; 5) infrared absorption properties of solutions, solids, and thin films; 6) fluorescent and phosphorescent properties of solutions, solids, and thin films at variable temperatures; and 7) thermal properties such as glass transition temperature and thermogravimetric properties with DSC/TGA.

The polymer and molecular characterization facility is currently used by permission from STAMI faculty members. In 2017, the facility will move to a new laboratory in the Molecular Sciences and Engineering building with plans for conversion into a cost center to increase usage by the broader Georgia Tech community. If you are interested in using the facility, please contact us.
