To tackle concerns associated with the water-energy nexus into providing a minimal barrier-of-entry electricity utilization and freshwater supplies to remote communities and decentralized areas. This dissertation addresses off-grid water supply and efficient electricity utilization in different conditional and geographical scenarios. Additionally, the interlinking of water and electricity was addressed by combining water generating methods with cooling devices like PV panels for an improved electricity usage. Firstly, a photovoltaic-membrane distillation-evaporative crystallizer was fabricated to provide simultaneous water and electricity generation. This device uses seawater as a water supply to provide fresh water with zero liquid discharge into cooling down the PV panel for an enhanced performance. Second, atmospheric water harvesting composite PDMAPS/CNT/LiCl was fabricated to demonstrate the salting-in effect for an improved water capture. This uses hygroscopic salt to capture and release water from the atmosphere. Finally, the AWH approach was used to fabricate an anti-corrosive composite PDMAPS/CNT/Clay/IL into cooling electronics through evaporative heat dissipation with improved adhesive properties.Citation

Metal- And halide-free, solid-state polymeric water vapor sorbents for efficient water-sorption-driven cooling and atmospheric water harvesting(Materials Horizons, Royal Society of Chemistry (RSC), 2021) [Article]Metal- and halide-free, solid-state water vapor sorbents are highly desirable for water-sorption-based applications, because most of the solid sorbents suffer from low water sorption capacity caused by their rigid porosity, while the liquid sorbents are limited by their fluidity and strong corrosivity, which is caused by the halide ions. Herein, we report a novel type of highly efficient and benign polymeric sorbent, which contains no metal or halide, and has an expandable solid state when wet. A group of sorbents are synthesized by polymerizing and crosslinking the metal-free quaternary ammonium monomers followed by an ion-exchange process to replace chloride anions with benign-anions, including acetate, oxalate, and citrate. They show significantly reduced corrosivity and improved water sorption capacity. Importantly, the water sorption capacity of the acetate paired hydrogel is among the best of the literature reported hygroscopic polymers in their pure form, even though the hydrogel is crosslinked. The hydrogel-based sorbents are further used for water-sorption-driven cooling and atmospheric water harvesting applications, which show improved coefficient of performance (COP) and high freshwater production rate, respectively. The results of this work would inspire more research interest in developing better water sorbents and potentially broaden the application horizon of water-sorption-based processes towards the water-energy nexus.

Hybrid water vapor sorbent design with pollution shielding properties: extracting clean water from polluted bulk water sources(JOURNAL OF MATERIALS CHEMISTRY A, Royal Society of Chemistry (RSC), 2021) [Article]The shortage and contamination of local water resources have long been a challenge especially for off-grid communities without centralized water supply. The emerging solar photothermal distillation lacks the capability of handling polluted source water with a wide range of common environmental pollutants. Based on water vapor harvesting, this work reports a Simple Water Extraction Apparatus with Pollutant Shielding (SWEAPS) design which is able to efficiently produce clean water from various polluted liquid water sources and the atmosphere. SWEAPS is fabricated by encapsulating a water vapor sorbent by an omniphobic fabric. The omniphobicity of the encapsulation fabric endows SWEAPS with self-floating capability and the ability to screen out the contaminants in the source water. The self-floating properties of SWEAPS allow it to harvest clean water vapor right above the source-water–air interface where the relative humidity is close to 100%, leading to its much higher water harvesting capacity than that of the same material harvesting water vapor from the ambient atmosphere. Due to the chemical and physical stability, anti-bacterial, pollution and corrosion shielding effects of SWEAPS, it is demonstrated to produce clean water meeting the WHO drinking water standard from various polluted water resources, such as seawater, contaminated water, and amazingly untreated real domestic wastewater. SWEAPS has the potential to produce clean water for point of consumption at a decentralized scale and thus to improve the quality of life for those who need water most.
