Abstract

This paper analyzed the effective use time of Phenanthraquinone-doped polymethylmethacrylate(PQ/PMMA) photopolymer, the effective use time here and below refers to the number of days in which there is no significant change in the reproduction data page and Bit Error Rate(BER) when the material is recorded and read on the day it is made compared to when it is recorded and read after a period of time, we tentatively analyzed that PQ/PMMA underwent a short baking polymerization stage of 4 hours at 60°C, its effective use time can be extended by about 30% compared to the long baking polymerization stage of 10 hours, and the diffraction efficiency is also significantly improved, also dramatically reduces the exposure time required to record information on the material. The observations we illustrate here provide an idea for the preparation of PQ/PMMA materials with high-performance holographic properties and longer effective use time while reducing the time required for thermal polymerization.
