Abstract
A liquid dispersion includes a matrix phase of polymerizable material and at least 10% by volume of solid conductive particles distributed throughout the matrix. The conductive particles may have an average particle size of less than approximately 100 nm, and the liquid dispersion may have a viscosity of less than approximately 100 Poise. Such a liquid dispersion may be printed or extruded and then cured to form a solid thin film. The content and distribution of conductive particles within the thin film may reach a percolation threshold such that the thin film may form a conductive layer. Polymer-based devices, such as nanovoided polymer (NVP)-based actuators may be formed by co-extrusion of a nanovoided polymer material between conductive polymer electrodes.
