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.
介绍了一种具有二阶非线性光学性质的环氧/蒙脱石复合材料以及环氧/蒙脱石复合材料的交联方法。采用含色团的插层剂通过离子交换过程对蒙脱石进行修饰,形成有机蒙脱石,其中色团被整齐地包装在剥离的环氧/有机蒙脱石纳米复合材料上。因此,在自组装过程中观察到了光学非线性,即Pockels效应,而无需采用极化过程。此外,制备了一系列环氧/蒙脱石纳米复合材料,其中包括热可逆的呋喃-去氢莰Diels-Alder加合物,以建立交联特性。Diels-Alder交联改善了环氧/蒙脱石纳米复合材料的自对准行为、电光(EO)系数和时间稳定性。
