摘　　要：PMMA/LDH(layered double hydroxide) composite nanomaterials have been prepared. The relation between the content and dispersion of LDH in PMMA and the thermal stability and transparency of the composite materials has been investigated. The thermal stability of the composite materials was found increased with increase in the content of LDH. Uniform dispersion of LDH in PMMA favored increase of the thermal stability of the PMMA/LDH composite materials with a less loss of their transparency.PMMA/LDH(layered double hydroxide) composite nanomaterials have been prepared.
