Aramid nanofiber-reinforced graphene oxide frameworks for durable and flame-resistant fire warning sensors

Currently, fire warning sensors utilizing nanomaterials gained attention in research and development sectors. Among these, graphene oxide (GO)-based sensors stand out for their promising features in fire detection systems. However, GO sensors still suffer from poor durability, short-alarming time and poor solvent resistance. In this study, GO is modified with melamine diborate (M·2B) and incorporated into aramid nanofibers (ANFs) to develop GO-MB@ANFs nanopaper via mechanical mixing followed by vacuum-assisted filtration self-assembly. ANFs cross-linked graphene oxide sheets within a 3D scaffold while M·2B plays a critical role in enhancing flame retardancy of GO-based nanopaper. GO-MB@ANFs nanopaper features…
