Abstract: Epoxy/MMT composite material and a crosslinking method for epoxy/MMT composite material with second order nonlinear optical properties are introduced. Chromophore-containing intercalating agents are applied to modify montmorillonites (MMTs) to form organoclays by an ion-exchange process, wherein the chrmophores are neatly packed on exfoliated epoxy/organoclay nanocomposites. As a result, optical nonlinearity, i.e. the Pockels effect is observed for the nanocomposites without resorting to the poling process due to self-assembly process. Furthermore, a series of epoxy/MMT nanocomposites comprising thermally reversible furan-norbornene Diels-Alder adducts are prepared to establish a crosslinking feature. Self-alignment behavior, electro-optical (EO) coefficient and temporal stability of the epoxy/MMT nanocomposites are improved by the Diels-Alders crosslinking.

Abstract: A facile synthesis of amphiphilic hyperbranched polymers consisting of poly(amic acid) and polyimide was developed via “A2+B3” approach from difunctional anhydride and trifunctional hydrophilic poly(oxyalkylene)triamine. Various amphiphilic hyperbranched poly(amic acid)s (HBPAAs) with terminal amine functionalities and amic acid structures were prepared through ring-opening polyaddition at room temperature, followed by thermal imidization process for the formation of hyperbranched polyimides (HBPIs), accordingly. The resulting HBPIs were analyzed by GPC, indicating the molecule weights of 5000˜7000 g/mol with a distribution of polydispersity between 2.0 and 3.8. The amine titration for HBPIs indicated the peripheral total-amine contents to be 8.32˜18.32 mequiv/g dependent on compositions.
