Enhanced Substrates for Controlled Explosive Properties

Optical microscopy and SEM images of PETN films on low surface energy (left) and high surface energy substrates (right). Fracture cross-sections (bottom) show a reduction in porosity and increase in density for PETN grown on high surface energy substrates.
