▎ 摘　　要

NOVELTY - Reducing laser ignition energy of energetic material involves preparing photothermal conversion material with a two-dimensional sheet-layer nanostructure into a self-supporting film and directly attached to the energetic grain, where the photothermal conversion materials include graphene oxide, graphene oxide 3-aminophenol formaldehyde composite, graphene oxide polytetrafluoroethylene composite, and MXene polytetrafluoroethylene composite. USE - Method for reducing laser ignition energy of energetic material. ADVANTAGE - The method enhances the photo-thermal conversion efficiency of the laser ignition device, so as to reduce the initiation energy of the laser photo-thermal ignition.
