摘要:
Novel composite materials are synthesized by incorporating N-acryloylmorpholine (ACMO) in highly concentrated phenanthrenequinone (PQ) doped poly(methyl methacrylate) (PMMA).The photosensitizer concentration of PQ was increased from 0.7 wt.% to 1.8 wt.%.The doping of ACMO component results in a higher diffraction efficiency and photosensitivity than a typical PQ/PMMA system.The enhanced performance of the material may stem from the ACMO molecules,which might open a new route for improving the holographic performance of the PQ/PMMA photopolymer.
