▎ 摘　　要

NOVELTY - Melamine chemically-modified graphene oxide hybrid nanomaterial (I) is new. USE - Hybrid nanomaterial (I) used as nanofiller to prepare a high-heat-resistant flame-retardant polymer nanocomposite. ADVANTAGE - Organic covalence and non-covalence technologies are perfectly combined, and the thermal stability of the hybrid nanomaterial (I) is greatly improved compared with that of the unmodified graphene oxide. The effective control for the dispersing performance of functionalized hybrid material in a solvent is realized. The preparation method is simple, efficient, and easily implemented in large-scale and has simple post-treatment. DETAILED DESCRIPTION - Melamine chemically-modified graphene oxide hybrid nanomaterial of formula (I) is new. An INDEPENDENT CLAIM is included for preparation of hybrid nanomaterial (I).
