文摘
- •
Indigo carmine anions were intercalated into a layered zinc hydroxide salt.
- •
The synthesis occurs by co-precipitation in slightly alkaline conditions.
- •
The obtained deeply blue material mimics the Maya Blue pigment.
- •
After dehydration at 200 °C, sulfonate groups are grafted to the layers.
- •
Intercalation is an alternative method to transform soluble dyes into pigments.
