Nanoenergetic material composite having remote ignition characteristic by high-power pulsed laser beam and method of preparing same

A nanoenergetic material composite having a remote ignition characteristic by a high-power pulsed laser beam, the nanoenergetic material composite being in a form of thin film type pellets that are prepared by compressing a multiwalled carbon nanotube/nanoenergetic material (MWCNT/nEM) composite powder and have a nitrocellulose (NC) thin film for waterproofing formed on a surface thereof, wherein the multiwalled carbon nanotube/nanoenergetic material (MWCNT/nEM) composite powder is prepared by adding multiwalled carbon nanotubes to a nanoenergetic material, which is a mixture of fuel material nanoparticles and metal oxidizer nanoparticles, and the multiwalled carbon nanotubes enhance a combustion rate of the multiwalled carbon nanotube/nanoenergetic material (MWCNT/nEM) composite powder by delivering thermal energy upon remote optical ignition by the high-power pulsed laser beam.

A method of preparing a nanoenergetic material (nEM) composite having a remote ignition characteristic by a high-power pulsed laser beam, the method comprising:

• a process of preparing a nanoenergetic material by mixing fuel material nanoparticles and metal oxidizer nanoparticles;
• and
• a process of preparing a multiwalled carbon nanotube/nanoenergetic material composite powder by adding multiwalled carbon nanotubes (MWCNTs) to the nanoenergetic material and then performing mixing using ultrasonic energy.
