Abstract: Described herein are methods for coating porous substrates with a polymer and for drying or curing polymers at conditions different from ambient pressure conditions. The disclosed methods utilize a process of pressure infiltration of a polymer solution into pores of the porous substrate, which can result in filling very small pores of the porous substrate to a high volumetric degree, such as up to 100%, in a relatively short amount of time and using a relatively short number of process steps, providing for high coverage and intimate contact between the polymer and the surface of the porous substrate, including inside pores of the porous substrate.

Abstract: Multi-terminal capacitor devices and methods of making multi-terminal capacitor devices are described herein. The multi-terminal capacitor devices may include a plurality of individual capacitors arranged in a single device layer, such as high surface area capacitors. A individual capacitor may include an aluminum foil-based electrode, an aluminum oxide dielectric layer conformal with the aluminum foil-based electrode, and a conductive material electrode, such as a conducting polymer or a conductive ceramic, in conformal contact with the dielectric layer.
