Functional nanofibers to decompose toxic chemicals in fabrics

May '08
Nylon nanofibers coated with metal nanoparticles
The position and distribution of the electrical charges on the nanofibers will be fed into computerized fluid dynamics algorithms developed by Andrey Kutznetsov of NC State to predict the trajectory of the nanoparticles challenging the filter. Hinestroza and NC State's Warren Jasper pioneered work in this area a couple of years ago.

The second project, in collaboration with the University of California-Los Angeles (UCLA), will study the incorporation of a new type of molecules called metal organic polyhedra and metal organic frameworks onto polymeric nanofibers to trap dangerous gases as toxic industrial chemicals and chemical warfare agents, then decompose them into substances that are less harmful to humans and capture them for further decontamination. The synthesis of these molecules was pioneered by Omar Yaghi of UCLA.

This project will also look into the potential toxicity of these nanofiber-nanoparticle systems to humans in collaboration with Andre Nel from UCLA Medical School.

Hinestroza's research group specializes in understanding and manipulating nanoscale phenomena in fiber and polymer science.

Sheri Hall is assistant communications director for the College of Human Ecology.
