Abstract Scope |
Like chameleons, numerous living organisms can rapidly alter their appearance in response to stress using plasmonic or structural color. Additionally, for centuries, artists have used metallic nanoparticles to create color (without knowing it). Nowadays, colloidal nanoparticles have shown interest due to their strong size and shape-dependent properties, especially color change by modifying particles’ spacing in material.
Current formulated BIC inks are colored using dyes and pigments. However, such products present various issues as toxicity for dyes or stability for pigments. Hence, this project focuses on providing a new generation of more sustainable and environmentally friendly coloring agent by exploiting the plasmon effect of metallic nanoparticles. Particularly, two nanoparticles synthesis methods using chemical and photochemical processes, have been developed and discussed in this study. Finally, these results open new routes of creation of hybrid materials allowing to generate color changing inks inspired by nature. |
