METHOD OF MANUFACTURING A TRANSPARENT AND BIREFRINGENT THIN SOLID MINERAL LAYER AND OPTIC COMPONENT WITH A TRANSPARENT AND BIREFRINGENT THIN SOLID MINERAL LAYER
摘要
A method of fabricating a transparent and birefringent mineral solid thin layer comprises the following steps: a) preparing a colloidal solution constituted by anisotropic mineral nanoparticles in suspension in a dispersion liquid; b) depositing the colloidal solution on a surface of a substrate by spreading as a thin layer while applying directional shear stress tangentially to the surface of the substrate so as to deposit the colloidal solution as a liquid thin layer on the surface of the substrate, the value of the shear stress and the concentration of mineral nanoparticles in the colloidal solution being determined in such a manner as to cause the anisotropic mineral nanoparticles to be aligned along the direction of the shear stress tangential to the surface of the substrate; and c) drying the liquid thin layer by evaporating the dispersion liquid.
