Multilayer graphene make lead styphnate more safer to electrostatic hazard

摘要

Lead styphnate (LS) is a widely used primary explosive, which is very sensitive to electrostatic spark, and frequently results in unexpected troubles. To improve the security of LS, multilayer graphene was used to modify its' anti-electrostatic performance. Products with various contents of multilayer graphene (mass fraction: 0.1% to 2%) was prepared. The SEM was used to characterize the morphology of the samples. The electrostatic spark sensitivity and static electricity accumulation of the obtained samples were investigated with a desirable result, which confirmed that multilayer grapheme can make LS more safer to electrostatic hazard.
