Formation Conditions

We report formation of complex responsive fibers consisting of a low molecular weight liquid crystal (LC) core surrounded by a polymer sheath using simple airbrush or jet spraying techniques. The fibers are formed using a solution of LC and polymer dissolved in a common solvent. With proper control of the solution composition and formation conditions the fibers self‐assemble. The diameter of the resulting fibers can be adjusted over a range spanning from one to tens of microns. The core of the fiber retains all of the responsive properties associated with low molecular weight LCs. A nematic LC core's director aligns along the long axis of the fiber making them highly birefringent. An electric field applied across the fiber changes both the director alignment and the optical properties of the fiber. Alternatively, thermochromic fibers are formed using a cholesteric LC in the core. Unlike similar electrospun fibers, the airbrushed fibers can be sprayed as continuous mats on virtually any surface or woven into textiles. The resulting fabrics can be made into displays, thermochromic temperature sensors, or for detection of chemical or biological agents. They offer numerous opportunities for wearable textiles that respond optically to a variety of stimuli.
