PhenoSystems (Belgium)

By utilizing photo acid generators (PAGs) that are suspended in polymer materials it is possible to formulate a gel containing chemicals necessary to create a robust gas reaction when the photo acid is present. The photo initiated chemical reaction produces gas from two reactions. The UV photo-degradation and the acid catalyzed degradation of the polymer. This process can be further enhanced by the design of the polymer link structure and chemical amplification. The degradation occurs and continues both in the presence of the acid and UV irradiation. The acid only occurs in the presence of UV Irradiation, therefore the control of UV irradiation is an effective chemical reaction control mechanism or switch.
