NaN5/GO复合含能材料的制备及其性能
Preparation and Properties of NaN5/GO Composite Energetic Materials
摘要
Abstract
Sodium pentazolate(NaN5)is a nitrogen-rich compound with high energy density and rapid energy release rate.How-ever,its combustion suffers from slow burning rate,high sensitivity,and poor self-sustaining combustion.In this study,by using a coordination complex strategy based on NaN5 with graphene oxide(GO)and polydopamine(PDA),a series of NaN5-based composite energetic materials were synthesized via solvent evaporation and co-precipitation.The morphology and structure of the composites were characterized by scanning electron microscopy(SEM),Fourier-transform infrared spectroscopy(FT-IR),and X-ray photoelectron spectroscopy(XPS).The thermal decomposition behavior and mechanism were investigated using syn-chronous thermal analysis(TG-DSC)and reaction kinetics simulations.The combustion and detonation performances were eval-uated via hot-wire ignition tests.Results demonstrate that after GO/PDA modification,the structure of NaN5-3%GO-1%PDA is optimized from cubic crystal to porous folded layer with strong interfacial bonding.Compared with pristine NaN5,the stepwise decomposition temperature difference of NaN5-3%GO-1%PDA is reduced by 61.1℃,the activation energy decreases by 30.7 kJ·mol-1,and the detonation growth time is reduced from 33.33 μs to 16.67 μs,proving that NaN5-3%GO-1%PDA has a faster energy release rate.关键词
