A positively charged Mg-Al-nitrate layered double hydroxide (LDH) has been synthesized. The chemical composition, shape, electrical property and anion exchange property of the positive nanoparticle were studied. The results show that the basal spacing of the positive nanoparticle may be tailored. This is a promising method to prepare the precursor of polymer/LDH nanocomposite.
