AI Technical Summary

Technical Problem

The photoinitiation system of holographic polymer materials in the existing technology is too complex, with low reaction efficiency, low preparation efficiency, and insufficient photosensitivity, which limits their large-scale application.

Method used

A single-component photoinitiator is used to generate free radicals through homolytic cleavage of boron-carbon bonds, which directly initiates the polymerization of holographic recording monomers, simplifying the photoinitiation system, improving reaction efficiency, and enabling rapid preparation by excitation with visible light in the range of 420–700 nm.

Benefits of technology

It improves the reaction efficiency and photosensitivity of holographic photopolymer materials, shortens the holographic coherent exposure time, and enhances processing efficiency and diffraction efficiency, with a photosensitivity greater than 100 cm/mJ.
