The interlayer surface of MgAl layered double hydroxide(MgAl-LDH)was modified by exchanging about halfof the interlayer nitrate anions by dodecyl sulfate anions(DS)to get MgAl(H-DS)LDH,and then the MgAl(H-DS)was melt intercalated by LLDPE to get the LLDPE/MgAl-LDH exfoliation nanocomposites.The samples werecharacterized by Fourier transform infrared(FTIR)spectroscopy,X-ray diffraction(XRD),ion chromatography,transmission electron microscopy(TEM),and thermogravimetry analysis(TGA).The nanoscale dispersion ofMgAl-LDH layers in the LLDPE matrix was verified by the disappearance of(001)XRD reflection of the modifiedMgAl-LDH and by the TEM observation.The TGA profiles of LLDPE/MgAl-LDH nanocomposites show a fastercharring process between 210 and 370℃ and a higher thermal stability above 370℃ than LLDPE.The decomposi-tion temperature of the nanocomposites with 10 wt% MgAl(H-DS)can be 42℃ higher than that of LLDPE at 40%weight loss.
