| Résumé : |
Structural colors are widespread in myriads of natural living organisms measuring from tens to hundreds of nanometers. In recent years, amorphous photonic crystal films have received extensive attention due to their stable color rendering properties. However, the internal structure of the films is easy to be contaminated by liquid. Thus, self-cleaning performance has been considered as one of the main obstacles to the practical application of artificial structural colored films. In order to solve the issues, we used heptadecafluoro-1,1,2,2-tetrahydrodacyl trimethoxysilane to modify the structural colored films. The results demonstrated that the modified colored films showed super-hydrophobic (contact angle > 160°) and high oleophobic (contact angle > 150°) properties. The rapid production of water-resistant and oil-resistant structural color coatings by spraying is significant for expanding their application in outdoor conditions (e.g., acid–base, alkali base, pollution) for a long time. |
