浸渍提拉镀膜仪文献：通过浸涂带有聚多巴胺层状结构的仿生黑色素颗粒得到明亮结构的彩色薄膜

Some beautiful structural colorations found in nature are produced by microstructures of melanin. Polydopamine(PDA), produced by the self-oxidative polymerization of dopamine, is known as a mimetic material of melanin. Previous experiments by our group have shown that PDA-based structural color materials produced bright structural colors upon enhancing the color saturation through the absorption of light scattering. Herein, we describe the preparation of structural color films by a dip-coating of biomimetic melanin-like particles with PDA shell layers. Various parameters of the dip-coating method influencing the structural coloration were investigated in detail. Experimental results revealed that the obtained films exhibited bright and angle-dependent structural colors independent of a background color, i.e., black or white background. These findings provide new insights for the development of dye-free ink technologies.
