Abstract
Reaction of the surface of individual picric acid crystals to the nanoscale mechanical stimulation was studied to understand the processes responsible for the initiation of energetic materials. Three types of the local mechanical stimulation, i. e., nanoindentation, friction, and impact were performed by atomic force microscopy methods. It was found that the stimulation at a nanoscale leads to the disappearance of the material of crystal surface. Moreover, the response to mechanical stimulation differs with crystal faces. In addition, the observed effect slows down with humidity increase probably due to the interaction of the picric acid surface with atmospheric water.
