METHOD FOR PREPARING THIN FILMS FOR CHEMICAL OPTICAL SENSORS

摘要

Method for preparing thin films for chemical optical sensors. The invention relates to the development of thin films comprising acrylic polymers on a light-transparent material as optical sensors that contain a luminescent indicator, the light-emitting properties of said indicator changing depending on the concentration of a pre-determined chemical species present in the medium into which the sensor film is inserted. The films are obtained by thermal or photochemical polymerization of acrylic monomers in the presence of a polymerization initiator and of the luminescent indicator that is physically immobilized in the polymer network formed. The resulting thin films can be used for the determination of pollutants in water.
