摘要：
This study presents a novel series of structural color coatings synthesized by blending fluorinated acrylate emulsion (FPA) with light absorbers (T6721) within polystyrene (PS) microspheres. The innovative strategy of replacing inter-microspherical air with FPA, a material of higher refractive index, has significantly boosted the reflectivity of the colloidal crystals to 95.86 %, particularly enhancing UVA reflectivity to a peak of 89 %. These coatings also showcase exceptional UV stability, structural integrity, and improved hydrophobicity, resisting UVinduced fading. The coatings' performance profiles recommend their use in demanding applications such as the coatings and painting industries, with potential for broader adoption in high-performance sectors including aerospace and automotive. This research advances the field of structural color technology, offering a sustainable solution for durable and vibrant pigment applications. Future efforts will aim to scale the synthesis and expand industrial applications.
