Problems solved by technology

[0006] Colloidal sol usually adopts processes such as soaking and pulling, uniform gel filming and other processes to prepare films. A common defect of these methods is that they are only suitable for two-dimensional flat coatings, and cannot be coated on three-dimensional substrates.
[0007] Sol film formation is usually cured at a highe

Embodiment 1

[0022] Example 1: The commonly used glass-ceramic products cannot be used as cooking utensils for induction cookers because they cannot cut off electromagnetic waves. By coating the surface of glass-ceramic products with a nanometer film with wave-absorbing properties, it is possible to manufacture a cooker directly used in an induction cooker. A glass-ceramic cooker comprising the steps of:

[0023] 1) According to the method of the present invention, prepare a nanocomposite sol with wave-absorbing properties;

[0024] 2) Coating the nanocomposite sol on the surface of glass-ceramic cookware;

[0025] 3) Bake at a temperature lower than the softening point of the glass-ceramic, and cool naturally to make a glass-ceramic cooker that can be used in an induction cooker.

Embodiment 2

[0026] Embodiment 2: High-power LED lamps generally have the problem of difficult heat dissipation. By spraying a nano-film with infrared radiation properties on the plastic bracket of the LED lamp, the heat dissipation of the LED lamp can be effectively increased, including the following steps:

[0027] 1) Prepare a nanocomposite sol with infrared radiation properties according to the method of the present invention;

[0028] 2) Spray the nanocomposite sol on the plastic bracket of the LED lamp;

[0029] 3) Heating to 100-120 degrees Celsius and baking for 30-90 minutes, the surface of the bracket of the LED lamp will form a layer of nano-film that can dissipate heat through infrared radiation, effectively increasing the heat dissipation of the LED lamp.

Embodiment 3

[0030] Embodiment three: a kind of titanium alloy material that has the property of absorbing radar wave, its manufacturing process comprises the following steps:

[0031] 1) According to the method of the present invention, prepare a nanocomposite sol whose chemical composition includes nickel ferrite, ferric oxide and manganese oxide;

[0032] 2) Spray the nanocomposite sol onto the surface of the titanium alloy to form a thin film;

[0033] 3) Heating to 300 to 400 degrees Celsius and baking for 90 to 120 minutes to form a nano-film on the surface of the titanium alloy, which can not only absorb radar waves, but also protect the titanium alloy from corrosion.

Description

technical field [0001] The invention belongs to the field of material science, and relates to nanotechnology, sol technology, nanometer thin film manufacturing technology and related applications. The invention discloses a special nanometer sol and its film-forming method, which can form nanometer particles with special electromagnetic properties on the surface of a substrate. Thin film, which gives the material the function of absorbing and radiating energy. Background technique [0002] Nanotechnology: Materials with a particle size of less than 100 nanometers are called nanomaterials. Nanomaterials have the characteristics of small particle size, large specific surface area, high surface energy, and a large proportion of surface atoms, which have three major effects: surface effect, small size effect and macroscopic quantum tunneling. [0003] Sol: Sol refers to organic or inorganic nano- or micron-sized particles formed in a solvent through hydrolysis and polymerization...
