Holographic gratings recorded on a new photopolymer composed of photosensitive polymer binder
We suggested new photopolymer systems using polyacrylic acid (PAA), polyitaconic acid (PICA), and the photosensitive polymer (PP) as binders. The photochemical reaction of the photosensitive polymer binder and acrylamide monomers was studied by virtue of infrared spectroscopy. The holographic grating was elaborated by conventional optical interference method. ne dynamic behaviors of the grating formation were studied with the change of exposure intensity. We observed the variation of the diffraction efficiency during post UV exposure. The surface topographical change of photopolymer layer was also observed by atomic force microscope (AFM).
