Method for preparing coating layer having highly aligned nanomaterial in lyotropic liquid crystal matrix

Abstract

The present invention relates to a method for preparing coating layer having highly aligned nanomaterial in a lyotropic liquid crystal matrix. More specifically, it relates to a method for preparing coating layer having highly aligned nanomaterial by applying shearing force to a composite of nano material and lyotropic liquid crystal material after mixing the nano material and the lyotropic liquid crystal material. The present invention has an advantage in that orientation of nanomaterials, which have a high industrial utilization but are difficult to control orientation, can be controlled very easily and simply by applying a shearing force using a medium, such as a lyotropic liquid crystal matrix which is extractable from nature, thereby cheap and biocompatible. Further, the present invention can induce a highly aligned orientation of nanomaterials over a wide area, and can be applied to produce a plasmonic color filter film using a polarization dependent surface plasmonic resonance phenomenon of the oriented nanomaterials.
