Shutter effect, microscopic

To study the effects of composition on the photopolymerization behavior of acrylates, the group of Bowman et al. prepared gradient libraries where acrylate composition was varied in one dimension and light exposure was varied using a moveable shutter in the orthogonal direction [17-21]. An FTIR microscope was used to characterize the conversion across the samples and the data from multiple libraries was then used to derive kinetic models for the photopolymerization.
