High Performance Electroactive Polymers for Naval Underwater Acoustic Applications
Abstract
Program objective was to develop electroactive polymers with performance superior than current materials for Navy transducers an electromechanical transduction (i.e. smart skins) applications. Three approaches were proposed and 2 of them were investigated (the 3rd approach, which makes use of the polar-vector reorientation of liquid crystal polymers to generate high electromechanical efficiency, was not pursued due to funding limit). First, utilized the large strain associated with the molecular conformation change between different forms (polar and non-polar) to generate high electromechanical responses. New class of electroactive polymers, i.e. electrostrictive PVDF based polymers, have been developed and at the end of this program, a large quantity of the electrostrictive P(VDF-TrFE-CFE) terpolymer can be produced (^2kg/batch), making it possible for the future prototype device development. Explored approach of using the delocalized electrons in organic materials to significantly raise the dielectric constant of polymeric materials; thus, polymeric materials with dielectric constant higher than 1,000 have been realized. Polymeric materials exhibit.
