Dan D. Edie, Ph.D.

Research Interests: High Performance Fibers, Composite Materials, Polymer
                               Processing, and Rheology

In past research Dr. Edie and his students discovered that non-circular carbon fibers exhibited unique properties. This discovery has formed the basis for several Clemson patents and much of Dr. Edie's subsequent research. Dr. Edie and his students have applied liquid crystalline continuum theory to explain and predict the structure developed during the extrusion and drawdown of the discotic liquid crystalline precursor used to form pitch-based carbon fibers. Based on this breakthrough in rheology and carbon science, they have developed new extrusion dies, which can produce ribbon-shaped carbon fibers with extremely high thermal conductivities (three times that of copper).

In ongoing work, Dr. Edie and his students are applying a similar approach to create activated carbon fibers that are designed to adsorb specific molecules. The team is collaborating with Professor Thies' research group to produce pitch precursors with specific molecular structures. This unprecedented control precursor chemistry combined with careful control of process conditions has allowed them to produce activated carbon fibers with specific pore structures. Applications for these fibers range from environmental remediation to hydrogen storage.
