外文摘要：MgAl-LDH (layered double hydroxides) were prepared with CO(NH2)2,NH4Cl and NH3·H2O by the coprecipitation method,respectively.Corresponding composite membranes were prepared by the coating method.LDHs were characterized by WAXS,CO2-TPD and SEM.The morphology of the PVC/LDHs composite membranes were characterized by means of SEM.The thermal stability of the membranes was analyzed by air aging box and TGA-FTIR.The SEM results show that nano-particles can be compatible with poly(vinyl chloride) (PVC) matrix homogeneously by the stirring-ultrasound blend method with two steps.Furthermore,the air aging box results proved that MgAl-CO(NH2)2-LDH has the best effect on thermal stability of PVC.TGA-FTIR results show that MgAl-CO(NH2)2-LDH could adsorb more HCl that resulted from the degradation of PVC and improve the pyrolysis temperature of the first degradation stage by 15 K compared with PVC.
