Designing Full‐Color Holographic Plastic With High Reliability for AR Displays

ABSTRACT Full‐color holographic plastics with high reliability are highly anticipated for next‐generation augmented reality (AR) displays, yet their realization has remained a long‐standing challenge. Herein, we present a viable strategy by designing an orthogonal photopolymerization system, which comprises a linear terpolymer bearing fluoroalkyl and epoxy side groups, an acrylate mixture, and a bifunctional epoxide. This strategy yields high‐performance full‐color holographic plastic that exhibits both high optical quality ( η ave = 84.8%, n 1 = 0.052, haze = 1.9%) and remarkable reliability (>1000 h @85°C). Thanks to the ability to simultaneously deliver high diffraction efficiencies in the blue, green, and red spectral regions (e.g., 88%, 79%, and 88%, respectively), we successfully demonstrate a full‐color AR display. Mechanistic studies unveil that the bifunctional epoxide, which acts as an orthogonal reactive plasticizer in the acrylate radical photopolymerization system, not only facilitates holographic manufacturing by plasticizing the radical‐reactive system but also enhances reliability through subsequent cationic photopolymerization and crosslinking. This work establishes a practical route toward robust full‐color AR devices and underscores the critical role of polymer design in advancing optical display technologies.
