• Graphene oxide-based hybrid networks were fabricated via introducing multi-amino molecule with triple roles (i.e., cross-linker, fire retardant and reducing agent).

• The optimized hybrid network with mechanically robust, exceptional intumescent effect and ultra-sensitive fire alarm response (~ 0.6 s) can be used as desirable smart fire alarm sensor materials.

• Exceptional fire shielding performances, e.g., ~ 60% reduction in peak heat release rate and limiting oxygen index of ~ 36.5%, are achieved, when coated such hybrid network onto combustible polymer foam.

防火膨胀型、耐高温、机械柔性氧化石墨烯网络，具有出色的防火屏蔽和超快速火灾警告

• 基于氧化石墨烯的混合网络是通过引入具有三重作用（即交联剂、阻燃剂和还原剂）的多氨基分子制备的。

• 优化的混合网络具有机械坚固性、卓越的膨胀效应和超灵敏的火灾报警响应（~0.6 s），可作为理想的智能火灾报警传感器材料。

• 当将这种混合网络涂覆到可燃聚合物泡沫上时，可实现出色的防火性能，例如，峰值热释放率降低约 60%，极限氧指数约 36.5%。
