Layered double hydroxides intercalated with organic anions and their application in preparation of LDH/polymer nanocomposites.

Popis výsledku v původním jazyce

The intercalation of organic anions, namely acrylate, methacrylate, 2-acrylamido-2-methyl-1-propanesulfonate (AMPS), 4-vinylbenzoate, and 4,4?-azobis(4-cyanopentanoate) into Mg-Al and Zn-Al layered double hydroxides (LDHs) was studied. The coprecipitatedMg-Al-NO3 and Zn-Al-NO3 hydrotalcite-like compounds with MII/Al molar ratio of 2 were used as precursors. The anion exchange and rehydration of calcined LDH precursors were applied for the intercalation. The anion exchange appeared to be the most effective method; all examined organic anions were intercalated successfully by this way both in Mg-Al and Zn-Al host structures. The intercalated LDHs were used as comonomer and initiator for preparation of LDH/polymethacrylate nanocomposites: mixture of monomer and LDHs intercalated with organic anions were dispersed in aqueous phase and then the emulsion polymerization was performed in the presence of inorganic (nano)particles to obtain polybutylmethacrylate hybrid latexes. Nanostructured h
