Abstract:The photopolymers with a hydrophilic matrix as poly(vinyl alcohol), PVA, are versatile holographic recording materials in hologram recording experiments. They use water as solvent and they can be made in layers with several thickness. One of the photopolymers more used is composed of acrylamide as polymerizable monomer, PVA and water as binder.The pair: triethanolamine, TEA, and the dye yellowish eosin, YE, is widely used as initiator system due to its high sensitivity and efficiency. TEA is the radical initia… Show more
