PHOTO- AND THERMODEGRADATION OF HOLOGRAMS RECORDED IN NANOCOMPOSITE
The paper considers the stability and degradation of holograms recorded in the photopolymerized nanocomposite both during storage and under external influences –heating up to the glass transition temperature of the polymer matrix and exposure to ultraviolet radiation. The compositions with different...

| Summary: | The paper considers the stability and degradation of holograms recorded in the photopolymerized nanocomposite both during storage and under external influences –heating up to the glass transition temperature of the polymer matrix and exposure to ultraviolet radiation. The compositions with different nanoparticles are compared; the difference in the thermal stability of the recorded holograms is shown; the optimum component ratios ensuring the lowest degradation are found. Holograms are recorded on a nanocomposite material that is a liquid photocurable monomer composition containing ZnO or SiO2 nanoparticles and photosensitizers. |
