Effect of degree of hydrolysis of polyvinyl alcohol on the diffraction efficiency from the gratings recorded in polyvinyl alcohol with ferric chloride films

Polyvinyl Alcohol (PVA) is used as a polymeric matrix in different mixtures, which are employed to make of holographic, recording films. In this research, three grades of polyvinyl alcohol (PVA) namely fully hydrolyzed and partially hydrolyzed and technical where studied with the aim of determining the influence of PVA degree of hydrolysis on the diffraction efficiency. Therefore, we show preliminary results of holographic diffraction gratings recorded in films were made with PVA and Iron (III) Chloride.
