Abstract

Una capa o patrón de polímero de cristal líquido quiral (CLCP, por sus siglas en inglés) que comprende cráteres distribuidos en forma aleatoria de diámetro medio controlado en número y/o la densidad. La densidad y/o el diámetro medio en el número de los cráteres se pueden controlar, por ejemplo, por medio del ajuste de la humectación de un sustrato por medio de una composición precursora de CLCP, el tiempo de desarrollo de la composición precursora, y el espesor de la composición precursora aplicada.A chiral liquid crystal polymer (CLCP) layer or pattern comprising randomly distributed craters of average diameter controlled in number and / or density. The density and / or the average diameter in the number of the craters can be controlled, for example, by adjusting the wetting of a substrate by means of a precursor composition of CLCP, the development time of the precursor composition, and the thickness of the precursor composition applied.
