Preparation and Thermal Effect Study of Fluorographene/Boron Powder Composite Materials
Source abstract
Abstract
To overcome the problem of sticky oxide films hindering the complete energy release of boron powder during ignition, graphene fluoride (FG) was used. FG, selected for its high fluorine content, low hydrogen content, low surface free energy, and high thermal conductivity, reacts with boron to produce high combustion heat and large amounts of gaseous products, effectively removing the viscous oxide film and preventing boron agglomeration. FG was synthesized via shear emulsification cutting, and FG/B composites were fabricated via solvent evaporation. Thermal analysis and combustion heat testing revealed that the prepared FG flake had an average thickness of 1.56 nm. For 20% FG addition, the FG/B composite exhibited a 1.86-fold increase in combustion heat. Moreover, 20% FG addition effectively improved the combustion heat release of boron powder, making it comparable with the combustion heat release of high-energy metal powder/boron powder composites.
