Perfluoropolyethers (PFPEs) serve as an oxidizer when blended with micro- or nanometer sized aluminum fuel and have previously been shown to produce energetic composites in pour-molded epoxy resins, electrospun fibers, and foamed poly(urethane)s. However, various heated and/or solvent processing conditions have been shown to physio-desorb the PFPE from the aluminum particles thus lowering potential energetic performance. In order to circumvent this, we have utililized the chemical bonding of carboxylic acid functionalized PFPE to the oxide monolayer on aluminum particles. This work will discuss the preparation, characterization, and thermal properties of this system and thier potenial application in fused deposition for 3D printed strucutrual energetic components.
