Research Areas
- Technical Textiles and Textile Structures
- Health and Safety
- Nanosciences, Surface Modification, Fibers and Polymers
Surface modification of polymers, nanotechnology, smart polymers, nonwovens, structure/property/process relationships, Raman spectroscopy of polymers, polymer physics.
In particular, we try to covalently bond 1-10 nm thick coatings onto polymerics surfaces to introduce new functionality. My research group has developed antimicrobial treatments, and superhydrophobic materials (with water contact angles as high as 178 degrees). We have increased surface electrical charges, dye-sites, and stain resistance. We are currently working on ways to enhance electrical conductivity, UV and NIR absorption, and signalling characteristics for sensors. Of particular interest is the interplay of materials science with polymer physics using polymer chemistry to impart the desired functionalilty.

Dr. Michielsen received his Ph.D. in Chemistry from the University of Chicago in 1979 working with Prof. Stuart A. Rice. He did a Post-Doctoral Fellowship in the Chemistry Department at Stanford University under the direction of Prof. Robert Pecora. The then joined DuPont at the Experimental Station in the Polymer Products Department in 1980. In 1990, he moved to DuPont Fibers. Then in 1995, he joined the faculty of the School of Textile and Fiber Engineering at the Georgia Institute of Technology. In 2004, he moved to North Carolina State University in the Department of Textile and Apparel Technology and Management in the College of Textiles.
Recently, Dr. Michielsen has invented an antiviral fabric with collaborators at Emory University (Atlanta, GA). A new spinoff company, LaamScience, has licensed this material from NCSU to bring it to the marketplace.
