Fluorinated polymeric matrices are an attractive class of materials due to their applicability for use in various environments including use as high performance materials. Specifically, perfluoropolyethers (PFPEs) are low molecular weight oligomers that have low volatility, minimal shear thinning, and a viscosity that is nearly independent of temperature making them stable in extreme processing conditions. PFPEs are well-known to undergo accelerated thermal degradation in the presence of native metals and Lewis acids.The work presented herin is motivated by the potential of harnessing the energetic behavior as a result of degradation pathways facilitated by exothermic metal-mediated oxidation. Computational modeling/simulation supported by thermal experimental studies showed that micron- and nanometer sized aluminum Fomblin-Y (a PFPE) blended formulations produced a viable energtic material. These formulations serve as an additive in commerical, mechancially polymeric matrices including epoxy resins and poly(urethane)s. This work will discuss the preparation, properties, and characterization of these composite systems.
