preparation example Construction

[0029] The invention provides a method for preparing an evaporator with a double-sided arched flexible carbon film. The specific steps are as follows:

[0030] 1. Preparation of Double-sided Arched Flexible Carbon Membrane

[0031] (1) First cut the carbon cloth into the desired size (for example, 2*3cm), and then wash it with acetone, ethanol solution and deionized water for 10 minutes to clean the carbon cloth.

[0032] (2) After drying in air, put the carbon cloth into the magnetron sputtering system (560C). With a DC power supply as the sputtering source, the vacuum degree of the sputtering chamber was pumped to 9.0×10-4Pa through a mechanical pump and a molecular pump in turn, and then argon gas (100sccm) was introduced, and the pressure in the vacuum chamber was adjusted to 0.6Pa . The sputtering process uses a high-purity copper target (99.9%), and pre-sputters for 15 minutes before sputtering to remove oxides on the copper surface. Afterwards, sputtering was perform...

The sputtering process uses a high-purity copper target (99.9%), and pre-sputters for 15 minutes before sputtering to remove oxides on the copper surface. Afterwards, sputtering was performed for 30 min under the condition that the flow rate of argon gas was 0.5 and the power was 65 W, so that the sputtered copper was uniformly deposited on the carbon fi...

Abstract

The invention provides an evaporator with a double-sided arched flexible carbon film and a preparation method thereof. The evaporator comprises a double-sided arched flexible carbon film material, wherein the double-sided arched flexible carbon film material is obtained by calcining carbon cloth on which Cu-BTC grows. The two ends of the prepared double-sided arch-shaped flexible carbon film material are fixed to a base, and a distance between the highest point of the double-sided arch-shaped flexible carbon film material and the end face of the base ranges from 0.1 cm to 0.5 cm, so the evaporator is obtained. The evaporator disclosed by the invention can effectively and efficiently obtain energy from ubiquitous solar energy and a natural evaporation process, and meanwhile, fresh water and electric power are generated, so a new way for simultaneously solving the problems of fresh water resource shortage and energy is provided.

Description

technical field [0001] The invention belongs to the technical field of solar energy interface evaporation, in particular to an evaporator with a double-sided arched flexible carbon film and a preparation method thereof. Background technique [0002] With the acceleration of industrialization, water scarcity has become one of the most important challenges in the world. To this end, various methods have been employed to produce fresh water, but most of them suffer from environmental sustainability issues due to the use of fossil fuels. In recent years, the use of solar energy as the driving energy to desalinate seawater at the interface between evaporators and bulk water to obtain drinkable fresh water has been considered as a considerable and sustainable means to alleviate the water crisis. Unlike conventional solar evaporation, which needs to heat a large amount of water, solar-driven interfacial evaporation (SIE) can realize thermal localization with the help of phototherm...
