In this paper, an amino-rich graphene quantum dots (GQDs) were efficiently prepared. Hydrogenated carboxylated nitrile latex (HXNBR) was prepared by hydrogenation of carboxylated nitrile latex (XNBR) by residual hydrazine hydrate during the preparation of GQDs, and a large amount of amino groups on the GQDs were reacted with carboxyl groups on the XNBR. Hence, a novel-interpenetrating network HXNBR film containing GQDs was successfully prepared. The physical properties and aging resistance of the films were investigated. The composite films have ultraviolet-visible excited fluorescence. By comparing the fluorescence of the films, it was confirmed that HXNBR grafting of GQDs to form an interpenetrating network enables GQDs to be well dispersed in the matrix.

石墨烯量子点改性氢化羧基丁腈橡胶互穿交联膜的制备

在本文中，有效地制备了富含氨基的石墨烯量子点（GQD）。氢化羧基腈胶乳(HXNBR)是在制备GQDs过程中，利用残留的水合肼对羧化腈胶乳(XNBR)进行氢化而制备的，GQDs上的大量氨基与XNBR上的羧基发生反应。因此，成功制备了含有 GQDs 的新型互穿网络 HXNBR 薄膜。研究了薄膜的物理性能和耐老化性。复合膜具有紫外可见激发荧光。通过比较薄膜的荧光，证实 GQDs 的 HXNBR 接枝形成互穿网络使 GQDs 能够很好地分散在基质中。
