Abstract:
An energetic composite comprises a metal powder; poly(vinylidene fluoride) (PVDF); and poly(lactic acid) (PLA). The metal powder comprises micrometer- or nanometer-sized particles, and the ratio of PVDF to PLA is between about 1:3 to 3:1. The metal powder comprises between about 4-32% wt of the energetic composite, and the metal powder consists of aluminum (Al), magnesium (Mg), or boron (B). A method of making an energetic composite material, comprises melt-blending a metal powder with poly(vinylidene fluoride) (PVDF) and poly(lactic acid) (PLA).
