Case Study

Acid Yellow 49 for Preparation of Intercalated Layered Double Hydroxide Films

Acid Yellow 49 for Preparation of Intercalated Layered Double Hydroxide Films Tang, Pinggui, et al.Dyes and Pigments, 2011, 91(2), 120-125.

Layered double hydroxide (LDH) materials have anion exchange capabilities and composition flexibility, and are often studied as flame retardants, catalysts, and adsorbents. By embedding dye anions into the interlayer channels of LDHs films, colored functional films with excellent thermal stability and light resistance can be synthesized. For example, acid yellow 49 (4-[2-(5-amino-3-methyl-1-phenyl-1H-pyrazol-4-yl)diazenyl]-2,5-dichlorobenzenesulfonic acid, abbreviated as PPDB) can be embedded in the pores of the LDHs film, which can improve its thermal stability and light resistance, thereby preparing a yellow coating film with excellent thermal stability and light resistance.
Preparation of ZnAl-PPDB-LDH/alumina/aluminum film
· The PPDB anion intercalated film was prepared by the ion exchange method using the ZnAl-NO3-LDH/alumina/aluminum film as a precursor.
· The precursor film was immersed in the solution of PPDB (0.1 M, 100 mL) in a sealed beaker and maintained at 100 °C for 2.5 h.
· The film was then removed and rinsed five times with hot water and subsequently dried at 100 °C for 12 h.
