Example Embodiment

[0029] The present invention provides a method of preparing a evaporator having a double-sided arched flexible carbon film, and the specific steps are as follows:

[0030] 1. Preparation of double-sided arched flexible carbon film

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

[0032] (2) After drying in the air, place the carbon cloth into the magnetron sputter system (560C). With a DC power supply as a sputter source, the sputtering chamber is pumped into 9.0 × 10-4Pa by mechanical pump and molecular pump, then the argon (100 Sccm) is introduced, and the pressure in the vacuum chamber is adjusted to 0.6 Pa. . The sputtering process uses a high purity copper target (99.9%), pre-sputtering pre-sputtering for 15 min to remove the oxide of the copper surface. After the argon flow rate is 30 min, sputtering 30 min is sputtered under conditions ha...

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...
