Abstract

Localized manipulation of light interference and phase through surface microstructures provides new viable technologies for applications such as anti-counterfeiting, camouflage, high-density optical storage and display. However, the single-color rendering mechanism and the material’s intrinsic properties, such as hydrophilicity, low hardness and low melting point, limit the range of applications. In this paper, we propose a structural color based on ultrathin ZrO₂ thin films, which presents a visible full-spectrum color display. The structural color coating has ultrahigh flame retardancy, super UV resistance, super surface hardness and resistance to acid and alkali corrosion. The use of two different color development mechanisms realizes the hiding of the quick response (QR) code in visible light. The modified film exhibits superhydrophobic properties, unique anti-icing and self-cleaning properties, and shows the material’s potential for camouflage, anti-counterfeiting, military, marine and aerospace applications.

超薄双显色机制结构显色膜，具有防冻自洁性能

通过表面微结构对光的干涉和相位进行局部操控，为防伪、伪装、高密度光存储和显示等应用提供了新的可行技术。然而，单一的显色机制和材料的固有特性（如亲水性、低硬度和低熔点）限制了其应用范围。在本文中，我们提出了一种基于超薄 ZrO2 薄膜的结构性彩色涂层，从而实现了可见光全光谱彩色显示。该结构色涂层具有超高阻燃性、超强抗紫外线性、超强表面硬度和抗酸碱腐蚀性。采用两种不同的显色机制，实现了快速反应（QR）代码在可见光下的隐藏。改性后的薄膜具有超疏水性、独特的防结冰和自清洁性能，显示了该材料在伪装、防伪、军事、海洋和航空航天领域的应用潜力。
