An intercalated hybrid of polyacrylamide/layered double hydroxide prepared via in situ intercalative polymerization

A new intercalated hybrid of polyacrylamide (PAM)/layered double hydroxide (LDH) prepared via in situ intercalative polymerization procedure is reported. LDH with counterion ion of nitrate or dodecyl sulfate anion was employed for comparison. The obtained PAM/LDH hybrid was characterized by X-ray diffraction, infrared spectra, differential scanning microcalorimetry and X-ray photoelectron spectrum. The results reveal that the LDH modified with dodecyl sulfate anion can be used to obtain an intercalated hybrid, whereas PAM polymer chains can not enter the interlayer space of LDH with nitrate anion as counterion ion.
