Composite materials and their applications constitute a hot field of research nowadays due to the fact that they comprise a combination of the unique properties of each component of which they consist. Very often, they exhibit better performance and properties compared to their combined building blocks. Graphene oxide (GO), as the most widely used derivative of graphene, has attracted widespread attention because of its excellent properties. Abundant oxygen-containing functional groups on GO can provide various reactive sites for chemical modification or functionalization of GO, which in turn can be used to develop novel GO-based composites. This review outlines the most recent advances in the field of novel dyes and pigments encompassing GO as a key ingredient or as an important cofactor. The interactions of graphene with other materials/compounds are highlighted. The special structure and unique properties of GO have a great effect on the performance of fabricated hybrid dyes and pigments by enhancing the color performance of dyes, the anticorrosion properties of pigments, the viscosity and rheology of inks, etc., which further expands the applications of dyes and pigments in dyeing, optical elements, solar-thermal energy storage, sensing, coatings, and microelectronics devices. Finally, challenges in the current development as well as the future prospects of GO-based dyes and pigments are also discussed. This review provides a reference for the further exploration of novel dyes and pigments.
复合材料及其应用是当今研究的热点领域，因为它们包含了组成它们的每个成分的独特性质的组合。它们通常表现出比其组合构件更好的性能和性质。氧化石墨烯（GO）作为石墨烯的最广泛使用的衍生物，因其优异的性能而引起了广泛的关注。GO 上丰富的含氧官能团可为 GO 的化学修饰或功能化提供各种反应性位点，这反过来又可用于开发新型的基于 GO 的复合材料。本综述概述了新型染料和颜料领域的最新进展，其中 GO 作为关键成分或重要的辅助因子。强调了石墨烯与其他材料/化合物的相互作用。GO 的特殊结构和独特性质对所制备的混合染料和颜料的性能有很大的影响，通过增强染料的颜色性能、颜料的耐腐蚀性、油墨的粘度和流变性等，进一步扩展了染料和颜料在染色、光学元件、太阳能热能存储、传感、涂料和微电子器件等领域的应用。最后，还讨论了基于 GO 的染料和颜料目前发展中的挑战以及未来的前景。本综述为进一步探索新型染料和颜料提供了参考。
