Biomimetic Chiral Photonic Materials with Tunable Metallic Colorations Prepared from Chiral Melanin-like Nanorods for UV Shielding, Humidity Sensing, and Cosmetics

Langmuir, 2022
Many biological species combine the helical organization of cellulose or chitin microfibrils with broadband light absorption of black melanin to produce brilliant structural colors with metallic and glossy effects and other diverse functions. In this work, based on core-shell CNC@PDA chiral nanorods consisting of cellulose nanocrystals (CNCs) as the ...

The modulation of melanin‐like materials: methods, characterization and applications

Polymer International, 2016
The growing interest in melanin‐like materials makes a strong request for fabrication strategies, modulation methods of their morphologies and properties, and profound knowledge of their structure–property relationship. In this review, we summarize the state‐of‐the‐art modulation methods of melanin‐like materials, with respect to both their chemical ...

Electrochromic and conductivity properties: a comparative study between melanin-like/V2O5nH2O and polyaniline/V2O5nH2O hybrid materials

Journal of Non-Crystalline Solids, 2000
In this work, we report the synthesis and some properties of melanin-like/V2O5·nH2O and polyaniline/V2O5·nH2O hybrid materials that have potential applications in optics and electronics. The hybrid materials were obtained by an oxidative polymerization/intercalation process reacting the gel with the monomers of the polymers.

Polydopamine-Based 3D Colloidal Photonic Materials: Structural Color Balls and Fibers from Melanin-Like Particles with Polydopamine Shell Layers

ACS Applied Materials & Interfaces, 2017
Nature creates beautiful structural colors, and some of these colors are produced by nanostructural arrays of melanin. Polydopamine (PDA), an artificial black polymer produced by self-oxidative polymerization of dopamine, has attracted extensive attention because of its unique properties. PDA is a melanin-like material, and recent studies have reported
