Polyimide nanocomposites

When Tg[(CH2)3NH2]8 reacts with aromatic dianhydrides, it forms hyper-branched polyimide nanocomposite networks having a high thermal stability (up to 500 °C) as shown recently by Se kin et al. (Figure 41).

There are numerous other possible packaging combinations. Materials such as PET, polyamides and polypropylene are coated with silicon or aluminium oxide to create barriers for oxygen and organics. Clay-polyimide nanocomposites have been evaluated as barrier materials for oxygen, carbon dioxide and water vapour.
