CNT/PVA@carbon-cloth membrane for performance study of solar and electric-driven interfacial evaporation
The use of electricity-assisted solar-driven interfacial evaporation technology is an effective way to increase fresh water production,but how to obtain fresh water in a green and efficient way remains a challenge.Therefore,in this paper we used an acrylic plate with holes as a support device,sprayed a mixed solution of CNT and ethanol on the carbon cloth as a photothermal electrothermal membrane and combined with water supply channels and thermal insulation devices to form an efficient evaporation system.The evaporation performance test results showed that the net evaporation rate of the designed evaporation system was up to 1.5 kg·m-2·h-1 under 1 standard sunlight irradiation,while the net evaporation rate rose to 5.08 kg·m-2·h-1 under the combination of the current of 2 A,the evaporation rate was 0.6 kg·m-2·h-1 higher than the sum of the two energy inputs.In addition,this evaporation system is simple,easy to scale up,providing a new idea for the green and efficient enhancement of the fresh water production.
