Fabrication, characterization, and application in nanoenergetic materials of uncracked nano porous silicon thick films

▸ An improved technique is realized to fabricate uncracked nano porous silicon (PS) thick film, and its cracking mechanism is discussed in order to avoid the crack of PS thick film. ▸ The characterization and application of uncracked nano PS thick films are reported, and the fabrication of porous silicon nanoenergetic materials (PS nEMs) is fabricated. ▸ The combustion of PS nEMs is realized when it's ignited by single pulse laser and its combustion is self-sustained.
