Background

The emerging solar interfacial evaporation (SIE) technology is an effective measure to solve the problem of freshwater resources. Due to the excellent nanostructures, Electrospun Nanofbers materials usually exhibit some unique properties, which are favorable for the construction of solar interfacial evaporators with good performance.

Based on this, Prof. Weimin Kang and Jingge Ju of Tianjin Polytechnic University published a review summarizing the research progress of electrostatic spinning applied to solar interfacial evaporators.

How does electrospinning technology apply to solar interface evaporators?

In solar interfacial evaporators, electrospinning technology is applied to prepare nanofiber materials with unique porous structure, high specific surface area, high structural designability and flexibility.

Specifically, electrospinning is used to prepare solar absorbers, water transport channels, and thermally insulating structures in solar interface evaporators.

Nanofiber Membrane contains a large number of unevenly distributed pores, which promotes water transport from the bulk water to the surface and prevents the surface from radiating heat to the bulk water, thus effectively reducing downward heat transport losses and improving interfacial evaporation efficiency
