| description | A method of producing porous materials for optical elements, to the contact lenses and to the porous materials with gradient refractive index. A porous material producing method comprised of following steps: (i) producing the particles, (ii) distributing the particles within the mass of optically transparent polymer, (iii) forming the layers, (iv) exposing said layers to emission, (v) removing the particles from the layers to form the pores, and (vi) producing the porous material from these layers. In step (iv) said emission is used to heat up the particles and partly evaporate the base material around the particles so that they can be removed. In step (v) the formed pores are filled with a substance having a refractive index different from the refractive index of the base material. It simplifies the process of producing and expand functionality of a porous material with predetermined optical properties.
La présente invention concerne un procédé de fabrication de matériaux poreux pour éléments optiques, les lentilles de contact et les matériaux poreux ayant un indice de réfraction à gradient. Un procédé de production d'un matériau poreux selon l'invention comprend les étapes suivantes : (i) la production des particules, (ii) la distribution des particules à l'intérieur de la masse de polymère optiquement transparent, (iii) la formation des couches, (iv) l'exposition desdites couches à une émission, (v) le retrait des particules à partir des couches pour former les pores, et (vi) la production du matériau poreux à partir de ces couches. Dans l'étape (iv), ladite émission est utilisée pour chauffer les particules et faire évaporer partiellement le matériau de base autour des particules de telle sorte qu'elles peuvent être retirées. Dans l'étape (v), les pores formés sont remplis d'une substance ayant un indice de réfraction différent de l'indice de réfraction du matériau de base. Ceci simplifie le procédé de production et accroît la fonctionnalité d'un matériau poreux ayant des propriétés optiques prédéterminées. |
