Its preparation method and application.There is the coating sunshine to select absorbability, and photothermal conversion rate is high, barrier propterty is good, weatherability is good.
Background technology
With the change of energy form, the reserves of conventional energy resource increasingly decline, and replace height with clear energy sources as much as possible
The fossil energy of phosphorus content, it is the principle that energy construction should follow.China is the coal production state of maximum and consumption in the world
State, coal account for the 76% of commercial energy consumption structure, are the main sources of China's atmosphere pollution.Devoting Major Efforts To Developing new energy and can
The renewable sources of energy using technology by as the important measures to reduce environmental pollution.
Solar selectively absorbing coating, which is contemplated, to be proposed in last century the fifties.When sunshine incides coating table
When face, coating will produce reflection to sunshine, absorb, three kinds of phenomenons of transmission.In general, wave-length coverage contained by sunshine
In visible region and near infrared region, if in coating the transition energy level of material just with certain wavelength corresponding to energy
Match somebody with somebody, material will produce absorption to the light of respective wavelength in coating.The principle of selective heat absorbing coating is：Coating is in sunshine
The ripple of long-wave band absorbs as more as possible, while reflection to sunshine and transmits as low as possible, and the energy of absorption changes into heat energy,
Afterwards by appropriate technical transform into different applications, the thermoelectric material in such as solar water heater, photovoltaic industry.
In order to improve the efficiency of selective heat absorbing coating, the only effective method is to keep gathering the sun to greatest extent
Reduce its convection current and radiation heat loss as far as possible while energy., can be selective absorbing according to principle of absorption and the difference of structure
Coating is divided into following several：1. interference-type absorber coatings：There is the film preparation of different refractivity into composite membrane using multilayer is prepared,
Interference effect is formed between film so as to obtain selective absorbing；2. surface texture type absorber coatings：Construct micron-nanometer rank
Surface roughness, selective absorbing is formed to sunshine；3. metal-semiconductor composite construction：Semiconductor has narrower taboo
