"Multi-Component Responsive Fibers"

This research builds on our established strengths in multi-component polymer/liquid crystal systems (first in electrically responsive films and more recently in responsive fibers). We pioneered the development of fibers consisting of a low molecular weight liquid crystal core surrounded by a polymer sheath using phase separation and electrospinning. Most recently we have used airbrush and jet blowing techniques to form these multicomponent fibers. We are investigating the mechanism of formation and the properties of the results fibers.

The fibers are ideally suited for a variety of applications. Because they incorporate the exquisitely sensitive response of liquid crystal to external stimuli they can be used as sensors. The fiber morphology provides an intimate interface between the environment and the liquid crystals. Finally, the inherent flexibility and drapability of the fibers make them ideally suited for wearable devices.
