Dr. Stephen Michielsen (Steve)
Professor, Director of Professional Development of Graduate Scholars
Textile Engineering, Chemistry, and Science
- 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.

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 NC State University to bring it to the marketplace.
