Title (EN) OPTICAL DETECTION METHOD
(FR) PROCEDE DE DETECTION OPTIQUE
Abstract:
(EN) The present invention relates to a method for detecting the sensitivity of one or more polymers and/or one or more polymer blends to a compound, comprising the steps of: exposing a plurality of individual micro-deposits comprising the polymer(s) and/or polymer blend(s) to the compound; and, with the aid of interferometry, detecting a variation in the appearance of a group of micro-deposits exposed to the compound and/or a variation in the dimensions and/or the refractive index of at least one of the micro-deposits exposed to the compound, linked to an interaction between the polymer(s) and/or polymer blend(s) and the compound.
(FR) La présente invention concerne un procédé de détection de la sensibilité d'un ou plusieurs polymères et/ou d'un ou plusieurs mélanges de polymères à un composé, comportant les étapes consistant à : - exposer une pluralité de micro-dépôts individualisés comportant le ou les polymères et/ou le ou les mélanges de polymères au composé, et - détecter par interférométrie une variation d'aspect d'un ensemble de micro-dépôts exposé au composé et/ou une variation des dimensions et/ou de l'indice de réfraction d'au moins l'un des micro-dépôts exposé au composé, liée(s) à une interaction entre le ou les polymères et/ou le ou les mélanges de polymères et le composé.
