摘要

随着信息化社会的发展，显示技术向柔性化、高耐候性方向发展，染料系偏光片因其优异的耐高温高湿性能而受到广泛关注。本文系统总结了以聚乙烯醇(PVA)为基材的染料系偏光片的研究进展，重点阐述了其制备原理、PVA光学膜性质及其对偏光性能的影响。围绕提升染料系偏光片光学性能与耐久性的关键问题，讨论了染料分子结构优化、染料配方、染色工艺以及PVA基膜改性等多元化改性策略。相关研究表明，通过构建染料与PVA间的强界面相互作用，可显著增强染料在PVA基膜中的取向有序性与耐湿热稳定性；同时，PVA基膜的复合改性不仅提升了其力学与耐水性能，也为染料分子提供了更稳定的取向平台。最后，展望了染料系偏光片在面向柔性显示与严苛环境应用中面临的挑战与发展方向，强调了“结构–加工–性能”关联机制研究的重要性，为新一代高性能复合材料型偏光片的设计与开发提供了理论依据与技术路径。

Abstract

With the advancement of display technologies toward flexibility and high weatherability

dye-based polarizers have attracted widespread attention owing to their excellent resistance to high temperature and humidity. This review systematically summarizes recent research progress on poly(vinyl alcohol) (PVA)-based dye-type polarizing films

focusing on their preparation principles

PVA optical film properties

and the effects of these mechanisms on polarizing performance. To address the key challenges of enhancing optical performance and durability

diversified modification strategies are discussed

including molecular structure optimization of dyes

synergistic dye compounding

improvements in dyeing processes

and modifications of the PVA substrate. Studies have shown that constructing strong interfacial interactions between dyes and the PVA matrix can significantly improve the orientation order and moisture-heat stability of the dyes. Composite modification of the PVA substrate not only enhanced its mechanical and water-resistant properties but also provided a more stable orientation platform for the dye molecules. Finally

this review outlines the challenges and future directions for dye-based polarizers in flexible displays and harsh-environment applications

emphasizing the importance of establishing a “structure-processing-performance” relationship. This study provides a theoretical basis and technical pathway for the design and development of a new generation of high-performance composite-based polarizers.
