Paper Abstract

In this paper a dynamic diffusion model is presented in order to describe the monomer diffusion and photopolymerization during the grating formation in photopolymers. We have presented a simplified model before it, which did not consider the dynamic process of monomer polymerization. In this paper a dynamic diffusion model is presented which consider the polymerization rate of monomer is change with time. Monomer concentration will decrease because of photopolymerization, and the polymerization rate of monomer will also reduce with the decreasing of monomer concentration. So the polymerization rate of monomer should be a variable parameter. In this paper the polymerization rate of monomer is corrected, and the experimental data is fitted with this dynamic diffusion model, a perfect result is got, and the parameters were got by fitting experimental data. The theory good agree with the experimental results, it proves that this dynamic diffusion model is excelled than the simplified model.
