Consistent Determinations of the Diffusion-and Reaction-rate Coefficients for Photoactive Monomers under Holographic Exposure

摘要：

An analytical method was applied for quantitative determinations of the initial rate coefficients of diffusion and reaction for a photo-curable recipe in holographic photo-polymerization. The results showed that the initial diffusion rate kept within small discrepancy despite an order of magnitude difference in the curing light power, while corresponding differences were found for the decay constants of diffusion and reaction in the curing process. Polymerization kinetics was analyzed for both curing and post curing processes.
