The present invention relates to a nano-energetic material (nEM) composite having ignition and explosion characteristics by a low-power laser pointer beam and capable of being remotely and optically ignited by adding black powder to nEM composite powder, and a method of preparing the same. The nEM composite includes: nEM composite powder; and black powder used as a mediator for initial ignition to initiate ignition in response to a laser pointer beam and cause a nEM to be continuously ignited and consecutively explode by ignition heat.

A pyrotechnic composition includes a fuel, an oxidizer, flow and rate control agents and oleoresin capsicum as an irritant. The composition is useful in crowd control products. The composition contains rate control ingredients to maintain combustion at a temperature below the point of degradation of the oleoresin capsicum, balanced with a booster material to maintain combustion.
