Fabrication and response characteristic of liquid crystal composite device using laminated nanofibers

Abstract

The interaction between electrospun nanofiber and nematic liquid crystal has been studied. In our previous research, we reported the use of aligned nanofiber as an alignment layer in a twisted nematic liquid crystal device and homogeneous alignment liquid crystal device. In this reported, nanofiber is used to improve the response time of thick nematic homogeneous liquid crystal device. With increasing concentration of nanofiber, the decay time of the device decreased. We found that the relaxation time of the composite devices is independent of the device thickness but strongly influenced by the nanofiber concentration.
