Energetic ink

A system, comprising:

• a first substrate;
• and
• an energetic composite ink disposed at a first location on at least one external surface of the first substrate, the energetic composite ink comprising:
• a plurality of particles, each particle being a metal or metalloid fuel particle and having a plurality of internal pores;
• and
• a polymeric binder that is permeable to a desired solvent.

A method for forming an energetic material, comprising:

• disposing a composite ink in an inert configuration onto a substrate to form a non-reactive layer, the composite ink comprising:
• a plurality of particles, each particle being a metal or metalloid fuel particle with a plurality of internal pores;
• a polymeric binder that is permeable to a desired solvent;
• exposing the non-reactive layer to an oxidizer solution comprising:
• an oxidizer for the metal or metalloid fuel;
• the desired solvent;
• and
• activating the composite ink by allowing the oxidizer solution to infiltrate the plurality of internal pores and dry, where oxidizer remains within the plurality of internal pores after drying.
