Synthesis and characterization of hyperbranched poly(amine-ester)/lanthanum/montmorillonite nanocomposites

Amine-terminated hyperbranched poly(amine-ester)(HBP) dendrimer synthesized in our laboratory was used as a complex agent of the lanthanum(La3+) particles, and montmorillonite (MMT) as a stabilizer to gain HBP/La/MMT ternary nanocomposites. The results of TEM showed that HBP/La composites were deposited on the surface of the MMT layers within nanoscales. The sizes of clusters become larger and larger with the increase of MMT content. The information of DSC indicated that the Tg of HBP/La/MMT nanocomposites with 5–30 wt.% MMT were increased significantly.
