Abstract

Zn-doped MgAl-layered double hydroxides (LDHs) with M2+/M3+ = 2 and different molar ratios of Mg/Zn have been synthesized by modified homogeneous co-precipitation method and characterized by powder X-ray diffraction, Transmission electron microscopy, Fourier transform infrared spectrum and thermogravimetry, and differential thermal analysis techniques. The thermal stabilizing effects of different LDHs on PVC were studied by Congo red test and thermal aging test. All of the nanoparticles show plate-like morphology and the average diameter of particles is around 90 nm. Results show that the introduction of Zn increased the average bond length and area of the layers of LDHs, therefore enhanced the adsorption ability on HCl gas which was generated during degradation of PVC to improve the thermal stability of PVC. LDHs with molar ratio of Mg/Zn = 1.0 shows the best thermal stabilizing effect on PVC.
