Problems solved by technology

However, the low utilization rate of solar energy has been hindering the development and application of solar steam technology.
The Chinese patent "a composite material device" (publication number CN105442014A) uses a porous alumina template as a substrate, attaches metal particles to the inner wall of the hole, and utilizes the high light absorption rate of the metal particles and the optical trap formed by the surface porous structure More captures make the composite device have an absorption rate as high as 99% in the 200nm-10μm ultra-wide band, but the material of the device is expensive and it is extremely difficult to use it on a large scale
In this way, the water evaporation can be effectively promoted, and the water evaporation rate is 325% higher than that under natural conditions. The preparation of this photothermal material is relatively simple, and the preparation process is relatively simple, but it is difficult to operate, and the durability and reusability are difficult to guarantee.

Abstract

The invention relates to a carbon fiber electrostatic flocking fabric for realizing high-efficiency light-steam conversion and a preparation method thereof. Put a certain quality of single carbon fiber on the lower electrode plate that is connected to static electricity, fix the fabric coated with adhesive on the upper electrode plate, and the ground wire of the upper electrode plate is flocked under the action of high-voltage static electricity; Finally, it is dried in an oven to make the carbon fiber and the fabric firmly compound, and then the surface floating hair is removed to obtain a carbon fiber electrostatic flocking fabric; the flocking layer of the obtained carbon fiber electrostatic flocking fabric is carbon fiber, and the carbon fiber length is 0.5 ~ 5mm , the flocking density is 0.1~0.3g / cm 2 , the angle between the carbon fiber axis and the surface of the fabric is 70° to 90°. The carbon fiber electrostatic flocking fabric prepared by the invention has excellent stability, high-efficiency light-steam conversion capability and potential for large-scale application, and has practical significance for practical problems such as seawater desalination and wastewater treatment.

Description

technical field [0001] The invention belongs to the technical field of environmental energy application, and relates to a carbon fiber electrostatic flocking fabric for realizing high-efficiency light-steam conversion and a preparation method thereof. Background technique [0002] The water evaporation process driven by solar energy has broad application prospects in the fields of seawater desalination and wastewater treatment, and is of great significance to alleviate the current global water shortage problem. However, the low utilization rate of solar energy has been hindering the development and application of solar steam technology. The interface photo-steam technology localizes the energy converted by the light-absorbing material to the surface of the water body through the design of materials and structures, and efficiently heats the surface water, effectively avoiding the loss of energy to the water body and the surrounding environment under the traditional method, an...
