Large-scale fabrication of structurally coloured cellulose nanocrystal films and effect pigments

Benjamin E. Droguet et al.

Summary: This study achieved large-scale fabrication of cellulose nanocrystal photonic films in a roll-to-roll device by optimizing the formulation and deposition process. It demonstrated the potential of cellulose nanocrystals as sustainable materials for industrial applications, producing effect pigments and glitters as alternatives to existing products that may be harmful or unsustainable.

The visual appearances of disordered optical metasurfaces

Kevin Vynck et al.

Summary: “Nanostructured materials have emerged as a promising approach for material appearance design, focusing on creating structural colors by wave interference. However, other important aspects of an object's visual appearance have been neglected. In this study, a multiscale modeling platform was developed to predict the visual effects of macroscopic objects covered by disordered optical metasurfaces. By utilizing nanoscale resonances and mesoscale interferences, unique visual effects were created at the macroscale. This framework opens up new possibilities in fine and applied visual arts.”
