Description
Technical field
It is specially a kind of for desalinization and the Graphene of clean water treatment the present invention relates to technical field of water treatment
The preparation method of photothermal conversion materiat.
Background technology
Fresh water is one of base substance that human society is depended on for existence and development.China's water resources shortage per capita, occupies
The 108th of the world.China's seashore line length, some island and coastal varieties in saline-alkali areas and inland bitter area
Category lacks the area of fresh water.These regional people do not meet the water of sanitary standard due to drinking for a long time, produce
Various illnesss, directly affect their healthy and local economic construction.Therefore, fresh water is solved
Insufficient supply is the Tough questions that China faces.In order to increase the supply of fresh water, a favourable approach is just
It is the desalination for carrying out seawater or bitter nearby, especially for the dispersion of those water consumptions and remote area more
Suitably use the method.The method desalinated seawater or bitter is a lot, but routine method, such as：Distillation
Method, ion-exchange, dialysis, reverse osmosis membrane and freezing etc., will consume substantial amounts of fuel or electricity
Power.It is reported that the annual energy resource consumption for being used for desalinization in the whole world is converted into crude oil and about needs 1.3 hundred million tons, with
And come also have many other problems such as serious air pollution, greenhouse effects.Therefore, other are sought more
Clean continuable method and have important practical significance carrying out desalinization.Wherein, carried out using solar energy
Desalinization, has wide practical use.
At present, the desalination with Solar Energy of use is broadly divided into two classes：One is to carry out photovoltaic using solar energy
Generate electricity, then desalinated using electrical energy drive reverse osmosis unit, due to photovoltaic generation transformation efficiency in itself just
It is very low, and the energy consumption that exists of reverse osmosis unit in itself and life problems make its development limited.Two is to utilize solar energy
Fuel factor, by heat collector heating seawater make its distill desalination；Because capacity usage ratio is low, its work temperature
Degree is generally very low, and evaporation efficiency is not high；And to improve efficiency and be accomplished by building large-scale heat collector heating
Seawater, this undoubtedly increases the operation and maintenance cost of the technology；Because the equipment that the salinity high of seawater is caused is rotten
Erosion and pipeline blockage problem, are difficult to the technology barrier for overcoming in also being promoted the use of as large scale equipment.Therefore, mesh
The forward position of preceding technology development is exactly that, how more efficiently using solar energy and optimization apparatus structure, reduction makes
With and maintenance cost, improve service life.

Design principle of the invention is：
The present invention prepare grapheme foam material, it is microcosmic on be by the unordered stacking of graphene nanometer sheet formed it is grand
Black matrix material is seen, when illumination is mapped to material, light can lead to not to external reflectance inside its pore structure
Cross constantly reflection and refraction is finally fully converted to heat and is absorbed by material.This photothermal conversion mode can be
To the full extent simultaneously using the luminous effect and fuel factor of solar energy, the grapheme foam in air can be in illumination
Under the conditions of by quickly be heated to temperature (150~200 DEG C) very high.
Due to the very low (~0.3g/cm of its density3), grapheme foam can be swum on the water surface, due to graphite
The capillarity of microchannel in alkene foam, water can be penetrated into inside grapheme foam, and attached in the form of micro- liquid film
On the surface of graphene nanometer sheet；Because Graphene has high thermal conductivity, when illumination makes grapheme foam
After heating, heat heats water in being quickly transmitted to hole；Because the water in micro hole structure is with ultra-thin liquid film
Form exist, and active force between Graphene and hydrone is very weak, the energy barrier overcome required for water film evaporation
It is greatly diminished, therefore moisture in grapheme foam hole can quickly be converted into low temperature vapor spilling；Simultaneously
Due to siphonage, water outside foam by lasting suction foam inside and can repeat above-mentioned cyclic process, until
Water in container is vaporized completely.
In actual fabrication process, can be steeped Graphene is improved using polymer and the complex sintered method of Graphene
While foam mechanical strength, formed with super-hydrophobicity on its surface and possess the superficial layer of ultra-microporous, can
To prevent to be diffused into blockage of the micro orifice phenomenon caused by foam interior is separated out due to water intermediate ion, so as to ensure water
The transmission and evaporation for dividing can be carried out persistently；But water is to foam under being unfavorable for original state due to super hydrophobic surface
The infiltration of material, it is therefore desirable to which the contact surface to foamed material and water carries out hydrophilicity-imparting treatment, using surface chemistry
The method of oxidation, oxygen plasma treatment or coating hydrophilic polymeric layer is to be capable of achieving.
Beneficial effects of the present invention are as follows：
1st, under conditions of sunshine abundance, environment temperature is that the present invention utilizes Graphene in the range of 10~50 DEG C
The water evaporation speed that foam can be obtained is more than 1000 times of equal area water surface natural evaporation speed, is mesh
More than 5 times of preceding commercial heat collection type solar water evaporating apparatus efficiency.
2nd, due to thermal conductivity and hydrophobicity that Graphene is high, using the heat profit of grapheme foam evaporation moisture
High with rate, the vapor initial temperature for being formed is only 50~60 DEG C, is easy to condensation.
3rd, desalination and purifier simple structure, easy to use, with low cost is made using grapheme foam,
And small portable device is can be easily made, and electric energy or other energy are not consumed, it is easy to use.
4th, grapheme foam material is reusable and easy to clean, will not because salt is analyzed and caused by micropore
Block, therefore both can be applied to the distil(l) that desalinization can also be applied to sewage.
