Copper oxide nanorods based nanofibers membrane for solar-driven interfacial evaporation

Solar-driven interfacial evaporation system has attracted intensive attention owing to its great potential in harnessing renewable solar energy purify water. To further enhance the solar-driven performance, absorber structure with high light-thermal conversion efficiency is especially critical. In this work, polyvinyl pyrrolidone/poly(vinylidene fluoride co hexa fluoropropylene)/CuO-nanorods (PVP/PVDF-HFP/CuO-nanorods) membrane was prepared sequentially by electrospinning, heating and hydrothermal processes. The flexible electrospun used as photothermal layer system. evenly distributed CuO nanorods function absorbers. polystyrene foam an insulating layer, filter paper inserted middle of transport water layer. designed evaporator for using pure As a result, rate 1.11 kg/m2h 75.36%. outcome work provides desalination wastewater purification.
