More Than Piezoelectricity: Harnessing Electroactive Materials for Functional Energetics
Abstract
Over the course of the last few years there has been an increased interest in exploring energetics that have exhibit electroactive properties. Indeed, they offer the hope for reactive materials, from propellants to explosives, to be multifunctional and capable of control via external stimuli (smart materials). In early work by the Son group the terpolymer, tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride, in combination with nanoscale aluminum, demonstrated unique behavior that was attributed to its piezoelectricity. To fully harness these effects, one must understand their role in providing control to energetic materials. In this first year we have made significant progress in several areas of this research: 1) Understanding the flexoelectric effect for PVDF and THV; 2) initial synthesis of PVDF coated aluminum particles; and 3)synthesis of perovskite energetic crystals.
