Judgment of Far-infrared Materials and Material Efficiency

Atoms are the basis of matter. As long as the temperature of an object is above the absolute temperature, the atoms in it will vibrate under the influence of temperature (thermal energy), causing molecules (consisting of atoms) to vibrate in the same way, at the same time the maximum amplitude generated under certain specific modes is called resonance. In the case of resonance, the maximum energy is released, which is emitted to the outside in the form of electromagnetic waves. 

Far-infrared emitter:

The wavelength that affects the maximum energy in the resonance mode includes the atomic mass in the molecule, the length and strength of the bond. The far-infrared emitter is a material whose electromagnetic wave wavelength radiated by structural molecules is within the wavelength range of far-infrared.

The main source of far-infrared rays in nature:

In addition to sunlight being the main source, all organic materials have different far infrared emissivity.

Far-infrared stimulation principle:

Steps: Temperature (thermal energy) stimulates atomic vibration → Molecular resonance → Electromagnetic resonance → The wavelength is just within the far infrared. Materials that meet the above stimulation principles include:

  • Inorganic materials with large particles (micron level), high crystallinity (crystals generate vibration through molecular absorption of heat energy) and high hardness.
    • Ceramic materials: oxide, carbide, boride, silicide, nitride.
    • Because the particles of high crystalline far-infrared inorganic materials mixed into the end application materials are relatively large, the hardness is relatively high (linear and rotational deformation deflection <a modulus> is large).
    • Because of its high rigidity, more energy is needed to generate a certain amount of electromagnetic wave amplitude.
    • Because the particles of far-infrared materials are larger, there are fewer particles distributed on the entire surface, and the overall density of far-infrared rays is relatively low.
    • The relationship between the resonance wavelength of the emitted electromagnetic wave and the particle size:
  1. Taking tourmaline as an example, the emissivity of 2.67 microns is 0.973, but the emissivity of 0.2 microns can be as high as 0.991. From the perspective of the crystal structure of tourmaline, in the bonded crystal state with higher relative flexibility, the particle size of 200 nanometers (0.2 microns) can produce the highest far-infrared effect.
  2. 2.67 micron particles, each particle size is equivalent to the size of 2197 0.2 micron particles. The particles of the same mass are distributed on the same area of the material, in addition to the influence of the size factor, it also includes the issue of uniformity of distribution. Evenly distributed and fixed frequency of multiple particles, the emission efficiency of far-infrared rays is higher than that of a small number of large particles. At the same time, it produces more “harmonic waves”, which are structures that have electromagnetic waves longer than the resonance wavelength and have a stronger effect. For these materials, the bonding strength between atoms determines that the resonance frequency falls within the wavelength range of the far-infrared rays, and therefore the finer the power, the better the far-infrared effect is unchanged. It is worth nothing that the cost required to grind such a fine powder, as well as the possible adhesion fastness of the substrate, etc., are thorny issues.
  • Nano size, weak height, Van der Waals force stacking and bonding of composite Nano metal particles, resulting in a low deflection structure. Materials with finer particles and high far-infrared emissivity. The following is a representative example of this type of material.
    • Composite structure of silver-copper nanoparticle.
    • The size of silver copper nanometer is 2nm to 15nm. Produce a particle structure with a smaller particle size than the above material, so that the bonding structure between atoms that needs to produce the same far-infrared wavelength is weaker than the above mineral bond. That is to say, the nanostructure of this cluster configuration has a low crystal deflection, which can produce the far-infrared molecular resonance wavelength of life light waves.
    • The stacking structure of silver-copper nanoparticles produces a combination of “molecular structure electrical dipole resonance effect”, “crystalline bulk material lattice resonance effect” and “non-single material interference with environmental electromagnetic waves and temperature (Robustness)”, three effects in one, and adjusted to be synchronized with the height effect presented by the life light wave range.

How to achieve three effects in one? We use the following way to explain.

  1. First of all, silver-copper nanoparticles, if they are 2nm in size, it can be said to be a cluster between hundreds of silver atoms and hundreds of copper atoms. In this kind of aggregation, the binding force includes:
  • Between the same metal atoms, the Van der Waals force is much smaller than the metal bond.
  • Between different metal atoms, it is also smaller than the Van der Waals force of alloy bonding.
  • In addition, between the silver and copper atoms, because of the redox potential difference, a bonding force similar to the molecular electric dipole moment will be generated. The binding force of the electric dipole moment between silver and copper, because the redox potential difference is less than the potential value required to form a monovalent ion, the binding force of this nanostructure is also much smaller than the binding force of ionic bonds.
  1. The above three forces form a weak single bond structure with weak bonding force, but the combination of a huge number of the three bonding forces can form a nanostructure with sufficient structural strength.
    Simply put, the structure of tiny nanoparticles with weak single bonds produces precise molecular resonance frequencies with far-infrared wavelengths.

The reason why we say that this is a stable resonance frequency is that there are only three types of structure bases between each group, whether it is Van der Waals force or dipole moment bonding force.

  1. Silver atom and silver atom (Van der Waals force)
  2. Copper atom and copper atom (Van der Waals force)
  3. Silver atom and copper atom (Van der Waals force + dipole moment)

Therefore, the structure of the binding force composition is highly simplified than that of polymer materials (only three types), and a huge number of binding forces are generated (more than one million binding forces per nanoparticles), such a high degree of homogeneity and a large amount of force occurs in relatively very tiny nanocomposite particles, it will produce an extremely efficient far-infrared electromagnetic wave emission mechanism that produces almost no harmonic waves.

  1. Another important aspect is the multi-material characteristics of copper atoms and silver atoms, which produce a relatively “high strength and toughness” far-infrared emission effect. In other words, the materials itself can produce relatively stable far-infrared intensity for changes in temperature and environmental humidity within a certain range.
  2. The effect of weak and large homogeneity binding force is relatively easy to form amplitude efficiency. Such a silver-copper nanoparticle stack material, due to its high thermal conductivity, is easy to absorb body heat when worn on the body. After being heated to slightly lower than the body temperature, it emits heat in the direction of electromagnetic waves. In the process of releasing heat, the resonance wavelength of the original material design includes life light waves, and the stimulation wavelength released by the body is originally life light waves. Therefore, stimulation wavelength + material design band + the weak binding force that is easy to generate high amplitude waves + a large and uniform distribution of weak binding force, making the far infrared efficiency of the material present fantastic results.
  3. In addition, the high specific surface area of the nanoparticle will increase the surface activity, which will increase the efficiency of the surface to produce far infrared rays.

The processing cost of silver-copper nanoparticles is lower than that of ground ceramic powder or other far-infrared additives of various inorganic materials, at the same time, the fastness of bonding to the substrate and the processing cost are much lower than that of traditional inorganic materials. Because nanoparticles are tens to hundreds of times smaller than the smallest particles in the original powder technology, no matter in terms of emission uniformity, emission efficiency, emission wavelength accuracy, and even the processing cost of materials, all have overwhelming advantages.
