Title: Process for making carbon-based nano-rods from switchable ionic liquids and devices and processes incorporating same

Abstract

A method of making carbon-based nano-rods from switchable ionic liquids (SWIL) that incorporates the SWIL is disclosed. Resulting nano-rods provide adsorption and spontaneous desorption of water at selected relative humidity values that find use in selected applications and devices.
