Abstract

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.
