Abstract
A method is described for preparing a 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 method includes (a) injecting a composite of nanomaterial and lyotropic liquid crystal into a space between an upper plate and a lower plate in a laminate; and (b) applying a shearing force to the composite of nanomaterial and lyotropic liquid crystal.
Claims3
A method for preparing a coating layer, comprising:
- (a) injecting a composite of nanomaterial and lyotropic liquid crystal into a space between an upper plate and a lower plate in a laminate;
- and
- (b) applying a shearing force to the composite of nanomaterial and lyotropic liquid crystal,
- wherein
- the shearing force is applied by repeatedly changing the pulling speed to 1 to 3 μm/s and 9 to 15 μm/s so that the nanomaterial is alternately aligned perpendicular and parallel to the pulling direction.
