Abstract: Exfoliated nanocomposite, based on Zn, Al layered double hydroxide (LDH) and polystyrene (PS), has been achieved by in-situ atom transfer radical polymerization reaction from initiator-modified LDH. The exfoliated structure is characterized by X-ray diffraction and transmission electronic microscope. The results suggest that the exfoliated ZnAl(DS) LDH sheets with a thickness of less than 1 nm disperse individually in the PS matrix, and the thermal stability of the nanocomposite shows a marked improvement. When the 50 wt% weight loss is selected as a comparison point, the decomposition temperature of PS/LDH nanocomposite is about 45 degrees C higher than that of pure PS.
