Abstract

The invention discloses a photoinduced polymer holographic recording material and a preparation method thereof. The holographic recording material comprises, by mass, 0.1%-10% of physical gelators, 30%-90% of allyl monomers, 0.05%-5% of a photoinitiator system and 1%-50% of refractive index modulators. A photoinduced polymer dry plate is obtained by uniformly mixing the materials and coating the mixture on the surface of a substrate when the gelating temperature is higher than that of the materials, then decreasing the temperature and gelating transparent liquid and can be used for holographic recording. Solvent is not introduced to the whole production process of the photoinduced polymer holographic recording material, and environmental pollution is avoided.

Description

technical field

[0001] The invention belongs to the technical field of holographic photopolymer storage materials, and in particular relates to a solvent-free photopolymer holographic recording material and a preparation method thereof. Background technique

[0002] Traditional information storage technologies, such as magnetic disk technology, compact disc technology (CD), digital versatile disc (DVD) and Blu-ray disc (BD) technology, are all based on the two-dimensional storage mode of the material surface. With the development of miniaturization, this two-dimensional information storage technology quickly reached the storage limit. Therefore, exploring new technologies for ultra-high information storage capacity and storage density is currently a research hotspot in the information science and industry circles. Laser holographic data storage technology is a three-dimensional information storage mode that stores information within the entire volume of the storage medium. ...
