Abstract
High-density polyethylene (HDPE)/Mg2Al-layered double hydroxide (Mg2Al-LDH) nanocomposites with an ethylene-acrylic acid random copolymer (EAA)/Mg2Al-LDH master batch were prepared by melt-mixing. The structure of the nanocomposites was characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results demonstrate the formation of the nanocomposites with exfoliated/intercalated layered double hydroxides well distributed in the HDPE matrix. The nonisothermal crystallisation behaviour of master batch-based HDPE nanocomposites was studied by using differential scanning calorimetry (DSC). The crystallisation behaviour of HDPE/Mg2Al-LDH nanocomposites was well defined by the Avrami analysis and Jeziorny method, as well as the combined Avrami and Ozawa analysis (MO’s model). The results reveal that a very small amount of Mg2Al-LDH (1%) accelerates the crystallisation process in comparison with the neat HDPE, and the high crystallisation rate is attributed to the nucleating effect of the exfoliated nanoparticles. Overall, the exfoliated Mg2Al-LDH particles act as the nucleating agent, and therefore distinctly change the type of nucleation, growth and geometry of HDPE crystals. 36 Refs.
