Publication number: 20190056545Abstract: 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.Type: ApplicationFiled: August 9, 2018Publication date: February 21, 2019Inventors: Dong Ki Yoon, Yun Jeong Cha
