PREPARATION METHOD OF PLATELET

摘要

PURPOSE: Provided is a method for preparing a platelet which has a thickness of 0.2-1,000 micrometers and a diameter of 0.5-10,000 micrometers. CONSTITUTION: The method comprises the steps of applying a material to be processed into a platelet in a flowable or gaseous state to a substrate; consolidating it; removing it from the substrate; crushing or grinding it; applying it to the substrate such that a lamina pack having a thickness of 0.2-1,000 micrometers on the cross-section perpendicular to its surface is present; and treating the lamina pack stripped from the substrate in such a way that the material disintegrates into individual laminae and the individual laminae are reduced in size to a particle size of 0.5-10,000 micrometers. Preferably the material is a polymerizable and cross-linkable liquid crystal, and more preferably the material comprises a cholesterol material.
