摘要

柔性电子产品在各种应用中获得了极大的关注，包括可穿戴设备、疾病诊断和医疗保健监测。在这里，受皮肤的延展性和在变色龙身上观察到的变色原理的启发，设计了一种特殊的导电和可拉伸的结构彩色薄膜，用于可视化柔性电子产品。将聚（3,4-乙烯二氧噻吩）（PEDOT）、聚偏氟乙烯-六氟丙烯共聚物（PVDF(HFP)）和光子晶体（PC）结构通过电聚合、自组装、热蒸发和模板牺牲等工艺整合在一起制备了反蛋白石复合薄膜（PEDOT-PVDF(HFP)-IO薄膜）。由于PVDF（HFP）层的PC结构和PEDOT层的导电性，PEDOT-PVDF(HFP)-IO薄膜具有稳定的光、电双信号传感性能。值得注意的是，该薄膜具有交互变色能力，并且在动态运动中具有稳定而敏感的导电性，因此适合用作光电传感平台。本研究为柔性电子器件的可视化研究提供了一条新的途径。

Bioinspired PEDOT-PVDF(HFP) structural color film for visualizing flexible electronics

Flexible electronics have garnered significant attention in various applications, including wearable devices, disease diagnosis, and healthcare monitoring. Herein, inspired by the extensibility of skin and the color-changing principles observed in chameleons, a special conductive and stretchable structural color film is designed for visualizing flexible electronics. This inverse opal composite film (PEDOT-PVDF(HFP)-IO film) is fabricated by integrating poly(3,4-ethylenedioxythiophene) (PEDOT), polyvinylidene fluoride-hexafluoropropylene copolymer (PVDF(HFP)), and photonic crystal (PC) structures through electro-polymerization, self-assembly, thermal evaporation, and template sacrifice process. The PEDOT-PVDF(HFP)-IO film displays stable optical and electrical dual signal sensing, which results from the PC structures of the PVDF(HFP) layer and the conductivity of the PEDOT layer. Notably, the film exhibits an interactive color-changing capability, along with stable and sensitive conductivity during dynamic movements, making it suitable for use as a photoelectric sensing platform. This study can present a novel research approach for the visualization of flexible electronics.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
