At first, a chiral PAEI was obtained by step-growth polymerization of diol, N, N'-(1,3,5,7-tetraoxo-5,7-dihydropyrrolo[3,4-f]isoindole-2,6(1H,3H)-diyl)bis(4-hydroxybenzamide) with N-trimellitylimido-L-leucine. The blending of nanoclays with PAEI modifies the thermal property, and this change is strongly related to the dispersion of nanoclay in the polymer matrix. For this goal, positively charged chiral L-leucine was incorporated into the unmodified Cloisite-Na þ montmorillonite (MMT) for organomodification of MMT by cation-exchang method. Then PAEI/OMMT nanocomposites with different compositions were synthesized by solution intercalation method.

Preparation and Prospect of Polymer Nanocomposites Used in High Voltage Equipment

“…MPS3 (M represent bivalent metals, such as Mn, Cd, Zn and Fe and so on) is a good choice for the intercalation compound in the space of layers as flaky compounds [14]. Mallakpour et al [15] prepared PEI/OMMT nanocomposites by solution intercalation method, and they found the thermal property of materials strongly related to the dispersion of nanoclay in the polymer matrix. Chu et al [16] investigated Synthesis of nanoporous graphite-derived carbon/TiO2-SiO2 composites, and the SEM images of the composites prepared by intercalation compound method as shown in Fig.4.…”
