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 at least one lens-shaped micro-deposit (21) comprising the polymer(s) and/or polymer blend(s) to the compound; and illuminating the surface of the micro-deposit in order to detect a change in the spatial distribution of the intensity of the light reflected or transmitted by the micro-deposit, linked to a variation in the dimensions and/or the refractive index of the micro-deposit, as a result of 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 au moins un micro-dépôt (21) de forme lenticulaire, comportant le ou les polymères et/ou le ou les mélanges de polymères, au composé, - détecter en éclairant la surface de ce micro-dépôt, un changement de la distribution spatiale de l'intensité de la lumière réfléchie ou transmise par ce micro-dépôt, lié à une variation des dimensions et/ou de l'indice de réfraction de ce micro-dépôt, sous l'effet d'une interaction entre le ou les polymères et/ou le ou les mélanges de polymères et le composé.
