Ionic polymer metal composite capacitor

摘要

An ionic polymer metal composite (IPMC) capacitor is disclosed which includes a thin single layer non-hydrated ionic polymer substrate with conductive film electrodes applied to at least a portion of each side of the non-hydrated ionic polymer substrate. The disclosed capacitor is suited for providing thin capacitance structures made to substantially any desired dimensions and shape and may be particularly suited for short term power storage in low power electronics, sensors, micro-electronics, MEMs and high temperature applications. A method of manufacturing an IPMC capacitor is also disclosed including providing a thin single layer non-hydrated ionic polymer substrate, applying a conductive film electrode to both sides of the substrate, and attaching electrical connections to the electrodes. The disclosed method of manufacture may optionally also include heat curing the capacitor and coating the capacitor with at least one moisture-resistant protective coating layer.
