Abstract
The possibility to form polymeric materials with heterogeneously distributed nanopores from a photopolymerizable composite containing a non-polymerizable additive is studied. The diffusive redistribution of the composite components during photopolymerization by non-uniform initiation is simulated. The interlaced areas of the nanoporous structure and the homogeneous monolithic polymer are shown to be formed in the polymer bulk under the acting of the radiation with a periodic distribution of intensity. The influence of the initial concentration of the neutral component in the composite, the diffusion parameters of the polymerizable medium, and parameters of actinic radiation on the size of the nanoporous and monolithic areas are determined. The obtained computer simulation results are experimentally verified.
