The present invention relates to a method for preparing oriented
anisotropic particles comprising the steps of providing at least one
anisotropic particle, dispersing the one anisotropic particle(s) in a
medium, and freeze drying the dispersion of anisotropic particle(s) and
the medium. In another embodiment, the present invention relates to an
oriented anisotropic material comprising at least one anisotropic
particle dispersed in a medium and thereafter freeze dried. Another
embodiment relates to an article comprising an oriented anisotropic
material and at least one matrix, wherein the oriented anisotropic
material comprises a freeze dried anisotropic material.
