Abstract: This disclosure includes systems and methods for extracting water vapor from atmospheric air and, more particularly, but not by way of limitation, systems and methods for optimizing liquid water production from air, in some instances, taking into account diurnal variations. The systems comprise an adsorption zone an a desorption zone, an actuator to move a desiccant between the adsorption zone and the desorption zone. The liquid water production is optimized based, at least in part, on measurements of one or more of: an ambient air temperature, ambient air relative humidity, and a level of solar insolation.

Abstract: The disclosed technology relates generally to devices comprising conductive polymers and more particularly to electrochemical devices comprising self-compensating conductive polymers. In one aspect, electrochemical energy storage device comprises a negative electrode comprising an active material including a redox-active polymer. The device additionally comprises a positive electrode comprising an active material including a redox-active polymer. The device further comprises an electrolyte material interposed between the negative electrode and positive electrode and configured to conduct mobile counterions therethrough between the negative electrode and positive electrode. At least one of the negative electrode redox-active polymer and the positive electrode redox-active polymer comprises a zwitterionic polymer unit configured to reversibly switch between a zwitterionic state in which the zwitterionic polymer unit has first and second charge centers having opposite charge states that compensate each other, and a non-zwitterionic state in which the zwitterionic polymer unit has one of the first and second charge centers whose charge state is compensated by mobile counterions.

Abstract: This disclosure is related to materials with highly stable and reversible water sorption and retention properties, as well as formulations and methods for their manufacture and uses. Composite materials of the present disclosure can avoid weeping or leakage of liquid water at wide ranges in ambient relative humidities so as to be suitable for a variety of applications including thermal management, thermal energy storage, atmospheric water generation and dehumidification systems. Composites disclosed herein can comprise an ionomeric material and in some embodiments, a hygroscopic or deliquescent salt. Furthermore, composites disclosed herein can also include a water vapor permeable or support polymer material providing support for reversible expansion or volume changes during water vapor sorption/desorption cycling via porous and/or elastic character, thereby avoiding mechanical restriction that could cause weeping or leakage of liquid water.
