Solar-to-Thermal Energy Conversion & Utilization
Youhong develops hydrogel-based solar-driven water purification systems for efficient clean water production. The unique water states in polymer materials enable fast water evaporation from hydrogels with much lower energy demand. By integrating solar-absorbing materials with spatial distribution into hydrogels, She demonstrated high light-to-thermal conversion efficiency and ultrafast water evaporation under natural sunlight. She further designed the device systems to achieve high water collection efficiency. Check her publications below for more details:
Structure–Property–Function Relation of Engineered Gels
Youhong exploits surface engineering to control the topography and wettability, and structural design to tune the porosity and mechanical property of gels. These strategies make gels a versatile materials platform with deterministic physicochemical properties for understanding fundamentals of polymer-matter interactions, and practical applications in sensing, water purification, and environmental remediation.
